Li-Ion (or lithium-ion) batteries are rechargeable batteries. Li-Ion batteries are built to with a high energy density and only allow a slow loss of charge when not in use.
Ni-MH (or nickel–metal hydride) batteries are rechargeable batteries. Ni-MH batteries are built with 2 -3 times the capacity of Ni-Cd batteries and are comparable to Li-Ion.Featured Products >
Ni-Cd (or Nickel-Cadmium) batteries are rechargeable batteries. Ni-Cd batteries work well at low temperatures and have a good cycle life but have a high self-discharge rate.
