During storage periods, keep your lithium battery at a 40% charge state. Although it’s best to fully charge a battery before use, prior to storage of lithium-ion batteries it’s harmful to fully discharge them. The best battery manufacturers store lithium batteries at around 60 degrees and at a 40% charge level.
Should lithium batteries be left on Charger?
Though lithium batteries could be left on chargers at the appropriate voltage and current range, however this might be hard to maintain; it is therefore advisable to unplug device with lithium battery from charger when a certain charge level has been attained, to avoid stress on the battery
Should lithium batteries be fully discharged?
Lithium-ion batteries should not be discharged completely before recharging. They should be kept at charge levels between 30 and 70 per cent. Letting your battery drain completely will adversely affect its lifetime and capacity. If a battery is charged before it drains and topped off throughout the day, you will get more charge cycles.

How do you store lithium batteries?
In general, Lithium ion batteries (Li-ion) should not be stored for longer periods of time, either uncharged or fully charged. The best storage method, as determined by extensive experimentation, is to store them at a low temperature, not below 0°C, at 40% to 50% capacity. Storage at 5°C to 10°C is optimal.
How do you store lithium-ion batteries for a long time?
Lithium batteries should be kept at around 40-50% State of Charge (SoC) to be ready for immediate use – this is approximately 3.8 Volts per cell – while tests have suggested that if this battery type is kept fully charged the recoverable capacity is reduced over time.
Is it better to store a battery full or empty?
The Nickel-based batteries (like the eneloop batteries) can be stored at any state of charge. The Lithium Ion ones must be stored at 30-50% maximum charge for the best results. But it's better to store when they are fully charged when you're not going to recharge in a few months.

How to recover a lithium ion battery?
If a Lithium Ion battery is heavily discharged an attempt to recover it can be made using the following steps: 1 trickle charge (0.1C) until the cell voltage reaches 2.8 volts. If this does not occur after an hour the battery is probably unrecoverable. 2 fast charge (1C) until the cell voltage reaches 4.2 volts. If this does not occur after two hours the battery might be usable but with limited capacity. 3 constant charge until the charge current falls below 0.07C
How long does it take for a lithium ion battery to self discharge?
All batteries gradually self-discharge even when in storage. A Lithium Ion battery will self-discharge 5% in the first 24 hours after being charged and then 1-2% per month. If the battery is fitted with a safety circuit (and most are) this will contribute to a further 3% self-discharge per month.

You do realize that by completely discharging your battery before recharging, ...
What is the charge range of lithium ion?
Basically, you should operate it between a charge range of 30-80%. How much energy you discharge in one go is a measure referred to as depth of discharge (DoD), and it matters a lot. Lithium ions do not like a deep depth of discharge.
What happens when a battery discharges to zero percent?
When a battery discharges to zero per cent, it can wildly become unstable. If a batter comes close to that danger zone, a protection circuit in the battery will activate and kill the battery forever, functionally destroying the battery before it can discharge to a level where it’s in danger of exploding.
What is lithium battery?
Lithium-ion batteries are the most commonly used energy storage devices on various electronic devices, such as laptops, mobile phones and digital cameras. These batteries are preferred to others due to their stability and relatively low maintenance nature. Additionally, they have a low self-discharge rate.

Now although most Lithium-Ion batteries will perform well for 2-3 years, if you want to extend the life of your battery, you can following a few tips. First, before storing your battery, make sure it’s not empty. Over time, batteries will leak power so if it’s stored at no charge in it, there’s a chance it won’t accept a charge again.
What are the disadvantages of a fridge?
The greatest disadvantage of a fridge is, the batteries will take up space which you can’t use for food. And if by accident the cells get damaged, the can explode and ruin your fridge. So I’d say, save them at 40% in your cellar of other cool place that isn’t used a lot and check the capacity once a year. Reply.
Can a refrigerator battery rust?
The problem with a refrigerator is that it’s a damp environment, which could cause parts of the battery to rust. So, before you put the battery in the refrigerator, make sure you put it in a Ziploc bag. If you want to take extra precautions, I also suggest putting a desiccant in the Ziploc bag, along with the battery.
Can you store a battery at 40%?
The greatest issue with storing at 40% capacity is that if you suddenly need your battery – it’s only at 40%, whereas if you store it in the fridge it’s at 100% always — full capacity. Yes, it loses 6% per year in the fridge, but at 40% capacity and room temp it loses 4% — not a big difference.
Why should lithium batteries be charged?
Lithium based batteries should be charged because if it is stored when deeply discharged for a long period of time, the battery could become a hazard (it may explode) and hamper the safety of its handler .
