With a Nominal Voltage of 3V and a capacity between 80-90mAh, CR2016 batteries from Maxell offers a chance to stock up on batteries for your compatible calculators, key fobs and electronic toys. They are also found in medical equipment.
They are generally found on devices which are not constantly in use so the long life, low discharge and leakage rate explains why manufacturers commonly choose to fit the CR2016 cell to their products.
These lithium coin cell batteries are for single use only and are non-rechargeable once drained.
