Storing LiPo batteries: the general practice
How a battery is stored between uses affects how long it lasts. This guide gives the general practice; model-specific storage parameters, where a listing states them, take precedence for that model.

The widely used general practice is to store LiPo cells at a partial charge — roughly the middle of their range — rather than fully charged or fully empty, in a cool, dry place. Full charge storage accelerates ageing, and empty storage risks the voltage falling below a recoverable level over months. If you are storing cells for a season, check them periodically and bring any cell that has fallen low back to a storage charge with a proper charger rather than leaving it to decline further.
Physical storage matters as much as charge level. Keep terminals protected from short circuits: do not store loose cells in a bag with keys, coins or other metal objects, and keep cells in a container that prevents crushing and puncture. Keep stored cells away from heat sources and direct sun, and away from flammable materials where practical. For commercial quantities, local fire and storage regulations may impose additional requirements — check the rules that apply in your market rather than relying on general guidance alone.
Before returning a stored cell to service, inspect it for swelling or damage and check its voltage if your equipment allows. A cell that has swollen in storage, or that will not hold charge, should be retired through a recycling route. This guide states no storage parameter for any specific model on this site; where a listing states one, follow the listing.
