First off, you should avoid charging lithium batteries below sub-freezing temperatures. Using or charging the lithium battery at low temperatures can affect its performance. When lithium batteries are charged below zero degrees, the plating will form on the anode and cannot be removed.

Second, you should protect your battery from strong impacts or sharp objects. Do not drop the battery or put it in the toolbox with other items. This could cause damage to the protective circuits or dividers inside the battery.

What’s more, lithium batteries should be kept away from heat-generating components within the system or within the charger unit. Thermal runaway in lithium batteries typically occurs between 130 and 170°C. While this is well above the 60°C operating temperature rating, unexpected thermal runaway may occur due to proximity to heat sources, high discharge rates, high SoC, and aging cells.
