Ni Battery 3 Link

Yet, for the average consumer, the lowly AA NiMH battery remains a quiet hero. It powers remote controls, thermostats, and children’s toys without fear of fire. It starts your gas-powered generator in a blackout. It has outlived the toxic Ni-Cd and the expensive Ni-H₂, and it will likely outlive the first generation of poorly managed, fast-failing Li-ion batteries.
