*Usa a Li-Ion charger. Do not use a NiMh charger.
*To ensure longevity, it is not recommended to allow the battery to discharge below 2.5V.
*Do discharged below 2.5 volts or cycle life/performance will be reduced. Maximum charge voltage is 4.25 volts.
*Chemical composition is lithium manganese oxide
*4.2V max charge, 3.7V nominal charge
*Safer chemistry, so is not available with a protection circuit. But that means you must guard against overcharge and overdischarge themselves.
*Slightly lower energy density than ICR, but can sustain much higher discharge and charge rates.  Use these cells when an application calls for “high-drain” cells.
