Notes
These can be found at 1.5 volts in AA size and can therefore be a direct replacement
for Alkaline cells. The low internal resistance and high capacity make these batteries
an ideal choice. The shelf life is around 20 years.
Recommended for AA battery powered modules: Energizer Ultimate Lithium L91
Pairs of alkaline 1.5 V cells are the most common. Use D cells for maximum life and
AA cells where space is restricted. Typical capacity is 2Ah.
Example: Varta 4014 (D), Varta 4006 (AA)
Most cells are 1.2 V so two in series gives 2.4 V. These can match alkaline batteries in
capacity but as the charged voltage is lower they do not match the usable capacity.
These batteries self discharge at a faster rate than alkalines. If charging these cells in
circuit precautions must be taken to ensure that the maximum voltage on the
transmitter module is not exceeded.
Example: GP 270AAHC (AA)
Most cells are 1.2 V so two in series gives 2.4 V. Three in series can be used to give
3.6 volts. These do not have the usable capacity of an alkaline battery. These are
generally only useful if they are to be charged on a regular basis. If charging these
cells in circuit precautions must be taken to ensure that the maximum voltage on the
transmitter module is not exceeded.
