Lithium Rechargeable Batteries
Good Resources Battery University Lithium Cell Voltage 3.0 to 4.2V (cell voltage typically specified as 3.7V) Series battery packs: 2 cells in series: 6.0 to 8.4V (7.4V typ) 3 cells in series: 9.0 to 12.6V (11.1V typ) 4 cells in series: 12.0 to 16.8V (14.8V typ) Don’t allow the battery voltage to drop below 3.0V […]
NiMh Cell Voltage 0.9 to 1.5V (cell voltage typically specified as 1.2V nominal) General Notes High self-discharge rate of over 30% per month in common nickel metal hydride batteries There tends to be 2 grades of battery:- consumer where capacity may be higher but number of discharge cycles will be lower (big numbers are best), […]
The typical voltage range for an alkaline battery is 1.55V to 0.8V as it discharges.
General What does #CA discharge mean? If the capacity of a battery is 7Ah (amps x hours), 6CA discharge means 6 x 7 x A = 42A discharge. If the battery is 12Ah and the max discharge current is 5CA, the max discharge current will be 5 x 12 x A = 60A. What are […]
