A "charge cycle" is not a unit of time; the length of time spent charging or discharging does not affect the number of charge cycles. [1] 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 ...
Rechargeable alkaline: 5–100 [14] Nickel–zinc: 100 to 50% capacity [14] Nickel–iron: 65–80 5,000 Nickel–cadmium: 70–90 500 [26] Nickel–hydrogen: 85 20,000 [32] Nickel–metal hydride: 66 300–800 [14] Low self-discharge nickel–metal hydride battery: 500–1,500 [14] Lithium cobalt oxide: 90 500–1,000 Lithium–titanate: 85 ...
A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li + ions into electronically conducting solids to store energy. In comparison with other commercial rechargeable batteries, Li-ion batteries are characterized by higher specific energy, higher energy density, higher energy efficiency, a longer cycle life, and a longer calendar life.
A battery bank used for an uninterruptible power supply in a data center A rechargeable lithium polymer mobile phone battery A common consumer battery charger for rechargeable AA and AAA batteries. A rechargeable battery, storage battery, or secondary cell (formally a type of energy accumulator), is a type of electrical battery which can be ...

The Mn(II) formed is soluble in most electrolytes and its dissolution degrades the cathode. With this in mind many manganese cathodes are substituted or doped to keep the average manganese oxidation state above +3.5 during battery use or they will suffer from lower overall capacities as a function of cycle life and temperature.
