How to Store Lithium Battery?

Recently, it’s discovered that several individuals storing lithium batteries in their white goods, presumptively as a result of some well-meant teacher tutored them colder temperatures bog down the speed of energy discharge. Whereas the science behind the thought has advantage, most battery makers advocate against storing your batteries within the fridge for various reasons associated with safety. Thus if you shouldn’t keep your batteries next to the salad dressing, wherever ought to they be stored? Below, I ready some general tips of lithium ion battery storage safely.


The ideal temperature for storage is 50°F (10°C). The upper the temperature the quicker the battery can self-discharge however this can be not a problem in itself see you later because the correct State of Charge is maintained (see below). Temperatures below freeze won’t injury metal batteries as they contain no water however they must be bought to higher than freeze before charging or usage to avoid injury.



If you buy new (rechargeable) batteries, but you’re not immediately using them, keep them in the original packaging. This prevents that the batteries come into contact with other metals. Do not lithium ion battery storage in metal containers, and use a battery box or a plastic one. Avoid coins or other metals in the same box. If you can’t guarantee the positive terminals won’t be in contact with the negative ones, then use tape or plastic caps to cover the terminals. If batteries come in contact with metals, they can start conducting electricity.


The ideal storage wetness is five hundredth. The most issue with wetness is that condensation will build up between the terminals and in terribly wet conditions cause a brief that may cause the battery to overheat and even change state. As an additional safety precaution the terminals should have separate covers.

All batteries bit by bit self-discharge even once in storage. A metal particle battery can self-discharge five-hitter within the initial twenty four hours once being charged and so 1-2% per month. If the battery is fitted with a security circuit (and most are) this may contribute to an additional three-dimensional self-discharge per month.

Lithium batteries ought to be unbroken at around 40-50% State of Charge (SoC) to be prepared for immediate use – this can be some three.8 Volts per cell – whereas tests have advised that if this battery kind is unbroken totally charged the recoverable capability is reduced over time. The voltage of every cell shouldn’t fall below two volts as at now the anode starts dissolving inflicting copper shunts to make which is able to cause an irreversible loss of capability. Equally metal primarily based batteries will be broken by over-charging that causes the cathode to decompose.

When checking the voltage makes positive the battery has not been charged or discharged recently, is at temperature throughout and has been in an exceedingly vibration free atmosphere. The most effective thanks to try this is to store lithium battery at temperature for a minimum of an hour and a half.

Lithium-Ion Voltage ranges

If a metal particle battery is heavily discharged an endeavor to recover it will be made using the subsequent steps:

First of all, trickle charge (0.1C) till the cell voltage reaches two.8 volts. If this doesn’t occur once AN hour the battery is perhaps unrecoverable.

Secondly, quick charge (1C) till the cell voltage reaches four.2 volts. If this doesn’t occur once two hours the battery may well be usable however with restricted capability.

Thirdly, constant charge till the charge current falls below zero.07C.

Shelf Life

The following steerage relies on batteries that area unit unbroken at the proper temperature, the proper wetness and within the correct State of Charge. Beneath these conditions normal metal primarily based batteries will have a time period of up to 10 years. Military and Medical metal primarily based batteries will have a time period of up to twenty and years.

Use Electric Battery Storage Cupboard

If your business needs a large cache of batteries to power instrumentality and devices, or if storing giant tool batteries is critical for your daily operations, you would possibly wish to think about an avid battery storage cupboard to optimize employee safety. This may sound sort of a crazy coincidence, but battery cupboards area unit lined with proprietary hearth liner. This dry, hearth conclusion media provides each insulation and fire-suppression to stay your assets and personnel safe from dangerous lithium-ion battery fires. They’ll even return outfitted with access ports to charge your devices whereas reducing the danger of thermal events.

Lithium primarily based batteries need additional attention as improper storage will cause units to overheat and doubtless change state in an exceedingly method called thermal runaway. Many varieties even have each the negative and positive terminals on a similar aspect creating it straightforward to accidentally short out the unit on metal shelving if they’re left uncovered, thus it’s vital lithium ion battery storage  in an exceedingly correct method.
