Why doesn’t Servaas Products sell rechargeable lithium AA batteries?
You can search high and low, but at this point in time, no-one makes Lithium Ion or Lithium Polymer rechargeable AA batteries as a matter of safety. Lithium rechargeable cells are a completely different technology to NiCd or NiMH batteries. LiIon and LiPo batteries require controlled charging and discharging. Lithium battery cells are usually 3.0, 3.6 or 3.7 volts, which is quite different than the 1.2V cells that make up Nickel based batteries. If lithium cells are charged or discharged improperly, they can and do explode. The potential liability on the manufacturer of the batteries means no-one has been prepared to manufacture and sell rechargeable Lithium AA batteries.
