Understanding the charging temperatures that a battery can withstand is crucial. If batteries are not operated at an adequate temperature, charge uptake will be limited because ion combination will be delayed. High current can cause pressure to build up inside sealed batteries, resulting in explosions. Effects of Heat:
The batteries function reliably at room temperature but display dramatically reduced energy, power, and cycle life at low temperatures (below −10 C) 3,4,5,6,7, which limit the battery...
