Not to be confused with the legal term for hitting someone very hard.
In newspeak rechargeable battery or just battery, this device stores electrical energy in the form of a chemical potential difference.
| Technology | Vmax[(maximum voltage cells like this can sustain without being damaged)] | Vmin[(minimal voltage where the cell is usable, anything less might damage the cell)] | Amax (discharging) | Amax (charging) |
|---|---|---|---|---|
| NiCd | 1,28V | 0,9V-1,1V | 250mA-500mA | |
| NiMH[(Nickel metal hydride)] | 1,26V-1,45V | 0,9V-1,1V | 250mA-500mA | |
| Lead acid | 2,1V | 1,4V-1,75V | ||
| Li-Mn | 4,05V-4,1V | 2,7V-3,0V | 5A-10A | 1A-1,5A |
| Li-Po | 10A-15A | 1A-1,5A |
Charging and discharging rate is defined as the C-Rate. Usually you want to charge at half the rate of the nominal capacity (0.5C or C/2).[(this means that if you want to charge a cell with 1000mAh, you should charge it for two hours at 500mA or less)]
