How do I keep my lithium-ion battery healthy?

Should you leave a lithium battery on charge all the time?

The short answer is Yes, it is bad to leave your Lithium-ion battery plugged in. When you recharge your battery, if you charge it to the 100% level, do not leave it plugged-in. Yes, there is a safety circuit that will protect the battery from overcharging and prevent it from exploding.

Should lithium-ion batteries be fully discharged before recharging?

Unlike other types of batteries that need to be recharged throughout their storage time, lithium batteries do better at 40%-50% DOD (depth of discharge). Pro-Tip: After every 30 charges, allow your lithium based battery to completely discharge before recharging. This helps to avoid a condition called digital memory.

How do you keep lithium-ion batteries happy?

Storing Lithium-Ion Batteries

It is no problem to put a lithium-ion battery away for a year, just make sure there is some charge in it before placing it in storage. Something between 50% – 60% is ideal, that will give the battery a very long time before self-discharge brings the Voltage close to the danger point.

Do lithium-ion batteries need maintenance?

Lithium-Ion rechargeable batteries require routine maintenance and care in their use and handling. Read and follow the guidelines in this document to safely use Lithium-Ion batteries and achieve the maximum battery life span.

The Definitive Guide to Li-Ion Battery Care

How can I extend my battery life?

Do lithium batteries lose charge when not in use?

No matter what type of battery it is or what material it is made of, it will drain the charge even when not in use. Similarly, when not in use, Lithium-Ion batteries will drain. If you charge the battery when it is completely discharged, you will reduce its capacity.

Can I leave my lithium-ion battery in charger?

Armed with this knowledge, it becomes clear that if the correct voltage limit is set for the lithium ion battery you are charging, there should be no issue leaving a lithium ion battery on the charger.

What is the best way to charge lithium-ion batteries?

What is the lifespan of a lithium battery?

The typical lifespan of lithium-ion battery is around 2-3 years or 300-500 charge cycles – whichever happens first. One charge cycle is calculated as the period of use from fully charged to discharged and fully recharged once again.

Does charging overnight damage battery?

Put simply, you can safely charge your devices overnight without having to worry about damaging their internals. Modern electronics automatically stop pulling current once their batteries reach 100% charge. However, charging to full each time isn't ideal for battery longevity.

How do you prolong the life of a lithium-ion battery?

Minimize the amount of time the battery spends at either 100% or 0% charge. Both extremely high and low “states of charge” stress batteries. Consider using a partial charge that restores the battery to 80% SoC, instead of 100%. If that's not possible, then unplug the device as soon as it reaches 100%.

How do you store lithium-ion batteries long term?

Batteries should be stored away from sunlight, heat, and humidity. Keep the storage area ventilated and dry, and maintain a relatively steady temperature. The ideal battery storage temperature is around 59℉, but most room temperatures will suffice.

Why battery should not be discharged fully?

As long as there is a relatively steady amount of charge within the battery, this cycling causes little wear on the internal architecture of the battery. By some estimates, frequently fully-discharging can reduce your battery's capacity by 70% over 300 to 500 charge cycles!

Is it bad to leave lithium-ion batteries in the cold?

Now, researchers at the Department of Energy's SLAC National Accelerator Laboratory have identified an overlooked aspect of the problem: Storing lithium-ion batteries at below-freezing temperatures can crack some parts of the battery and separate them from surrounding materials, reducing their electric storage capacity ...

What wears out in a lithium-ion battery?

As a lithium ion battery wears out, the cathode material loses some of its lithium atoms. The cathode's atomic structure also changes such that it's less capable of moving ions in and out.

How far should you discharge a lithium-ion battery?

Battery experts suggest that after 30 charges, you should allow lithium-ion batteries to almost completely discharge. Continuous partial discharges create a condition called digital memory, decreasing the accuracy of the device's power gauge. So let the battery discharge to the cut-off point and then recharge.

Can a lithium battery last 20 years?

So, how long do Lithium-ion batteries last? To sum it all up, the bare minimum that most manufacturers expect from their batteries is around 3 years or 1,000 charging cycles (whichever is less).

How do you take care of a healthy battery?

At what percentage should I charge my phone?

Google's recommendation is similarly straightforward: “Charge as much or as little as needed. You don't need to teach your phone how much capacity the battery has by going from full to zero, or zero to full, charge.” Samsung advises charging regularly and keeping the battery above 50 percent.

Does frequent charging damage phone battery?

Frequently charging the phone can harm the battery's life. Also, it is recommended that you charge the device from 0-80% and then unplug the charger. Moreover, it is better if you wait until your phone's battery level drops to 10% or below and then plug it in for charing.

Should I discharge battery before storing?

Lithium-ion batteries can be fully discharged before being placed into storage. Yet, they should have a charge rate of roughly 40 percent. As mentioned earlier, lithium-ion should never have its cell voltage drop below 2 volts per cell and should not have a maximum voltage of 4.1 volts.

How do you store batteries when not in use?

DO preserve battery life by switching off a device and removing the batteries when it's not being used, and is not expected to be used for extended periods of time. DO practice proper battery storage by keeping batteries in a cool, dry place at normal room temperature.

Should you store lithium batteries in the refrigerator?

In short: no. While cold environments help maintain battery life, refrigerators and freezers are not safe to put batteries in. The moist environment will cause condensation on the batteries. This in turn will lead to rust or other damage.

Is slow charging better for battery?

Slow charging is the most preferred and most independent source of charging the EV battery. It provides the maximum battery life (cycle life) and is safer than fast charging, especially for NMC batteries. It is also the cheapest way of charging the EV battery since the EV owner only has to pay for the energy.
