Lithium-ion batteries are the most common battery in consumer electronics. They are used in everything from cellphones to power tools to electric cars and more. However, they have well defined characteristics that cause them to wear out, and understanding these characteristics can help you to double the life of your batteries — or more. This is especially useful for products that do not have replaceable batteries.

Battery wear is loss of capacity and/or increased internal resistance. The latter is not a well-known concept, but over time the battery is able to put out less amperage as the battery ages, and eventually the battery is unable to generate power quickly enough to operate the appliance at all even though the battery is not empty.

The standard disclaimers apply, all advice is for informational purposes only, CleanTechnica is not responsible for any damages caused by inaccurate information or following any advice provided. Also, new technology may change the characteristics spoken about, making them less or more relevant in the future or even rendering them obsolete.

Lithium batteries age from the following factors:

These articles explain each facet in detail and are worth reviewing if you’re interested in understanding the logic behind the following recommendations.

Time

Try to buy batteries when you need them, because lithium ion ages from the moment it leaves the assembly line. However, by following the recommendations below you can get a longer lifetime from the batteries you own. If possible, look for the date stamp on any battery powered item you intend to buy and try get the newest one. Often you will find it on there, either on the outside of the package or on the item itself.

Charging Cycles

One cycle is fully charging the battery and then fully draining it. Lithium-ion batteries are often rated to last from 300-15,000 full cycles. However, often you don’t know which brand/model of battery is in the item you buy.

Partial cycles will give you many more cycles before the battery wears out, so when possible do partial discharges and then recharge. Don’t intentionally drain a battery before recharging for lithium-ion batteries.

For some equipment this is not realistic, in electric lawnmowers and other outdoor tools for example, but the manufacturer will hopefully have selected a battery chemistry designed for this use case.

Storage/Operating Temperature

Try to keep your batteries cool whenever possible. Don’t store a cellphone or other portable lithium battery in a car on a hot day, and keep them cool when not in use (bring your portable tool batteries inside instead of leaving them in an unconditioned shed/garage). Park an electric vehicle in the shade or a reasonable temperature garage when possible. Many EVs have active cooling of batteries so that will take care of this for you, although you still save battery power by parking in the shade or a conditioned garage.

Also, your pocket is about 30ºC, so store your cellphone on a desk and out of direct sunlight if you’re in the office or at home when practical.

Charging Characteristics

Charge your battery at a slow rate when possible. For a cellphone, use a charger that is rated for about 1/4 of the battery capacity if you can. Avoid quick charging except for rare instances when you absolutely need the most juice as quickly as possible. Charging at 1/2 its capacity per hour is acceptable but chargers that can charge a phone in under 1.5 hours from empty can be very hard on the battery.

For power tools, try to get a slow charger instead of the quick chargers many of them come with. This is not always possible, but often is.

Don’t leave any device connected to the charger once charging is complete. In fact, you should aim to charge to a maximum of 80% (more on that below).

Discharging Characteristics

Try not to abuse your battery by pulling as much power as quickly from it as possible. For an EV, flooring the acceleration pedal on a regular basis is not good for the battery. Similarly, power hungry games can drain cellphone batteries quite quickly as well. If your phone gets hot from high power use (and not the sun or high room temperature), it is an indication that you are punishing the battery.

Sometimes taking it easy on batteries is not always possible because some products, such as lithium-ion powered tools, are hard on the battery by design (drills, lawnmower, snowblowers, etc.). In these cases, manufacturers will typically use batteries designed for high drain rates (but have lower capacity), but anything you can do to be gentle on even these batteries will pay dividends in longer life. For power banks, try to use the power at a moderate rate. USB models can be tricky to limit your current draw rate as a phone or tablet will draw what it wants up to the bank limit, but for non-USB items you can often try to limit how quickly it’s drawing power.

Also you can “hack” this issue by buying and using a larger capacity battery if your device can handle it. For the same power draw, a larger capacity battery will have a lower percent drain per hour. This also reduces cycle count.

For items you don’t use daily, check on your batteries from time to time in case they are draining themselves when not in use. For EVs and cellphones, this is not a noticeable problem, but for power tools and power banks it is a good idea to check on the battery every few months (or weeks if it drains itself quickly) and top it up to 50%-ish for storage.

Depth Of Charge

Unlike most other battery types (especially lead acid), lithium-ion batteries do not like being stored at high charge levels. Charging and then storing them above 80% hastens capacity loss. So charge the battery to 80% or a bit less if that will get you through the day/week. Most EVs have the ability to select a percentage to charge up to in the software.

Charging above 80% is not a big problem if you intend to draw it down quickly and need the full capacity. Of course, try not to do this regularly if you don’t have to. Avoid overnight charging of your phone unless it has a smart charging feature, such as some Apple phones. For Android phones, use Accubattery software or similar, which will beep at 80% charge as a reminder to unplug the cord. Charge to full in the morning if needed to get through the day.

Similarly, for your EV if you have a long driving day planned, setting the software to charge to full by morning (not storing the vehicle overnight at full) and driving until you are below 80% rather quickly will not cause much extra wear to your batteries.

In general, it’s the storage time above 75-80% that causes most of the extra high charge wear.

For storing batteries long term, charge them to about 50% and check on them every now and then.

Depth Of Discharge

According to many sources, lithium-ion doesn’t like being fully discharged. So try to avoid draining your batteries below about 25% when possible. If unavoidable, then charge it back up to above 25% as soon as possible so the time spent near empty is minimized.

Miscellaneous Battery Information

  • Lithium-ion batteries have no memory effect. This was a facet of Nickel Cadmium batteries that went out of style decades ago, yet this is a surprisingly common question people ask about any rechargeable battery.
  • Most name-brand devices use quality name-brand batteries, but some devices (such as cheap power banks or no-name products) use off-brand or grey market batteries that will not last for years no matter how much you baby them. Try to avoid buying products with these batteries because the money you save buying them translates into reduced product life.
  • For some devices, the charge gauge can fall out of calibration and give you incorrect readings. This can typically be fixed by either fully charging or fully discharging then recharging the battery back to full. However this is hard on the battery, so it’s not something you want to do regularly, but in the rare instance that this is the cause of your issues, then a full charge or charge-discharge cycle will solve it. Quickly draw the battery back down to 80% before putting it back in service.
  • Everything stated above is quite generalized, and with the various battery chemistries on the market, all of them have slightly different characteristics. Once facet may be stronger in one chemistry vs. another but in general the advice provided is applicable to all lithium battery chemistries.

End Of Life (EOL)

End of life for a lithium-ion battery typically occurs when the battery can no longer perform the function the user requires of it. Commercially, when a battery (pack) has reached 80% of its design capacity it is considered EOL, but for end users, it’s typically looked at as when the device (or battery pack) becomes unusable.

When your battery starts acting funny, it can mean it’s ready to be retired. Some Apple phones have the ability to calculate capacity remaining (it is buried in the settings) and Accubattery for Android can do the same thing if installed and used for at least a week.

These are some of the strange quirks you may run into that can occur with worn out lithium-ion batteries:

  • Device shuts down stating low battery even though it should have plenty of runtime left, even if it stated a decent percent charge remaining just minutes before
  • The battery percentage meter drops randomly
  • Charging finishes prematurely even though the battery did not accept much power
  • Sudden capacity drops without warning
  • Self-discharge rate soars and is often uneven
  • The battery (pack) gets very hot during charging (sometimes the charger shuts down due to this)
  • Pouch batteries can start bulging (seen on some cell phones)

Be sure to recycle all batteries at the end of their life as they contain valuable materials that can be recycled into new batteries.

A summary of the terminology used in the battery world:

Charging algorithm = Battery is charged at Constant Current, then near full charge (typically over 80%) the charger switches to Constant Voltage. The charging rate slows until the battery reaches 100% charge. Many EVs modify this algorithm.

C = Capacity of the battery

  • Battery ability to output power is measured in 1/C. 1C means the battery drained in one hour, 2C means 30 minutes (1/2 hour), 3C means empty in 20 minutes (1/3 of an hour) and so forth.
  • Charging can also be measured in C, 1C means charged in 1 hour, 0.5C charged in 2 hours, 2C charged in 30 minutes and so forth.
    Charge rates are not typically linear, the battery is typically charged more rapidly until it reaches the Constant Voltage stage.

Series = Multiple batteries linked in a chain to increase the total voltage of the pack.

Parallel = Multiple batteries linked side by side to increase amperage instead of voltage.

(x)S(x)P configuration = explains how multiple batteries are linked. 4S2P for example means 8 cells, four in Series and two Parallel rows

Volts (V) = Electric potential. Power outlets are measured in volts.

Amps (A)= Number of Coulombs of electrons carrying those volts.

Watts (W)= Volts x Amps. Energy/Power usage is often measured in watts. A kilowatt is 1000 watts. kWh is Kilowatts per hour.

Energy is measured in Joules and is convertible to Watts/second if you have a time component.

Power = Energy over Time. Typically measured in Watts. One Joule per second is 1 watt. The same number of Joules or Watts in half the time is twice the power.

Nominal voltage = Voltage used to calculate Watts of a battery.

Battery capacity = How many Ah of power the battery can output (when new).

Load = Device that uses the power from the battery.

Internal resistance of a battery affects its Power output. Increased internal resistance is the reduction in rate of Power output the battery can deliver. Energy output is affected somewhat by increased internal resistance.

Facing potential 40% tariffs on India-made solar modules, India’s Waaree Energies is doubling its manufacturing capacity at its Texas factory.

It’s adding another 1.6 gigawatts (GW) of solar module manufacturing capacity at its Brookshire factory, bringing the site’s total to 3.2 GW. The company didn’t indicate a timescale for when the capacity increase would be complete. The move is part of its strategy to reinforce its “larger strategy of de-risking its global footprint.”

The company first announced it would open the Texas factory in December 2023, its first footprint in the US. Its original plan was to have an initial capacity to manufacture 3 GW of solar modules annually by the end of 2024. 

Waaree plans to invest up to $1 billion to scale its annual solar panel production to 5 GW in Texas by 2027, which would make it one of the largest solar panel factories in the US.

Previous to manufacturing in Texas, the Mumbai-headquartered company, which is India’s largest solar module manufacturer, already supplied Indian-made solar panels to the US. But the US’s new reciprocal tariff on solar modules imported from India is 26%, adding to the existing 14.5% Section 201 tariff, bringing the total to around 40%. 

“At a time when the world is redefining the rules of global trade, we’re not waiting for the dust to settle – we’re building through it. … The strength of our US order book is a testament to the trust we’ve built, and this expansion is a signal – we’re here, we’re growing, and we’re deeply invested in powering America’s energy future,” said Dr. Amit Paithankar, whole-time director and CEO of Waaree Energies.

EcoFlow DELTA 2 power station bundle

Cover campsite and home backup with EcoFlow’s DELTA 2 and DELTA Pro Ultra flash sale bundles starting from $849

For today only, as part of EcoFlow’s second phase Mega Sale that is running through April 25, you’ll find flash offers taking up to 52% off two varying backup power solutions, with the first being the bundled DELTA 2 Portable Power Station that comes with an expansion battery and a waterproof bag at $899 shipped or you can grab just the station and battery from Amazon at $849 shipped. The 3-in-1 bundle from the direct sale normally goes for $1,877 at full price, which we don’t normally see, as it’s usually the station and the bag that get bundled for $449 or $499 in these flash savings. Outside of these short-term discounts, the station and battery combo averages around $999 with the cuts, meaning you’ll be getting one of the best values while these deals last, regardless of whether you go with or without the additional bag.

A solid option to support you through outdoor travels as you enjoy the Earth’s bounty, EcoFlow’s DELTA 2 power station starts at a 1,024Wh LiFePO4 capacity that will instead be bumped to 2,048Wh thanks to the extra battery, and which can go higher to 3,074Wh with one more added on. It provides you with 15 port options with a steady 1,800W power output that will surge to 2,200W to meet larger appliance needs, bolstered by the X-Boost tech that also improves recharging rates. Plugging the station into a wall outlet will have the battery back to 80% in about 80 minutes, with it also accepting a maximum of 500W of solar input that can refill it in as fast as three hours time, with ideal conditions. With it rated for 3,000 life cycles, you can use and recharge the battery every day for over eight years, so with weekend or non-daily usage it will last you far longer.

The second of these offers gives you the brand’s more comprehensive and expandable DELTA Pro Ultra power station with a trolley for $4,799 shipped, coming down from $6,297 and $200 under the trolley-less offer from Amazon. This is the brand’s most expansive unit that you can invest in over time down the road, giving you a 6.1kWh LiFePO4 capacity to start with up to 7,200W of power output. Those numbers, with the addition of additional equipment, can go as high as a 90kWh capacity and 21.6kWh output with three inverters (stations) that are each given five batteries, which is great for folks looking for whole-home backup setups (especially if you have roof panels to regularly keep it all juiced up, though this will also require the brand’s Smart Home Panel 2).

Be sure to check out the full lineup of EcoFlow’s phase 2 Mega Sale, which is taking up to 65% off an expanded list of units from the first phase, complete with bonus savings and starting from $119 through April 25.
