2. Nickel–metal hydride battery - Wikipedia

   en.wikipedia.org/wiki/Nickel–metal_hydride_battery

   A nickel–metal hydride battery (NiMH or Ni–MH) is a type of rechargeable battery. The chemical reaction at the positive electrode is similar to that of the nickel–cadmium cell (NiCd), with both using nickel oxide hydroxide (NiOOH). However, the negative electrodes use a hydrogen-absorbing alloy instead of cadmium.

   This makes NiMH batteries better suited for high current applications than alkaline batteries. [10] Self-discharge rates are comparable between NiMH and alkaline batteries during the first six months. [10] Rechargeable alkaline batteries produce a voltage of about 1.5V, compared with NiCd and NiMH batteries which produce about 1.2V. For some ...

7. Charge cycle - Wikipedia

   en.wikipedia.org/wiki/Charge_cycle

   Each battery is affected differently by charge cycles. [2] [3] In general, number of cycles for a rechargeable battery (the cycle life) indicates how many times it can undergo the process of complete charging and discharging until failure or starting to lose capacity. [4] [5] [6] [7]
