Avoid short circuits, as they can release tremendous current
Never dispose of batteries in a fire
Safe chemistry LiMN reduces the risk of venting with flame or explosion. IMR-safe chemistry batteries do not include built-in protection circuitry, resulting in a slightly shorter battery length that fits most mods well. It is advised not to discharge the battery below 2.5V to ensure longevity.
IMR cells lack a built-in protection circuit and should not be discharged below 2.5 volts, as it can reduce cycle life and performance. The maximum charge voltage is 4.25 volts.
