Battery Care Tips (for longer battery life): Don't store batteries unused for long periods of time with less than 20% of charge.
Cycle batteries at least once every 2-6 months to keep them active. Store batteries in a cool dry location away from direct sunlight or high temperatures. Avoid moisture or condensation.
Optimal temps for storing batteries is between 50°F - 86°F (not advised to freeze batteries in the fridge).
Charge batteries to 40% or more before leaving them unused or for long term storage (3 months+).
Once a battery charger indicates batteries are fully charged, remove the batteries from the charger and unplug from the wall.
