Towards the end of its life its charge holding capability may be reduced. The battery may be obtained from ABACUS ELECTRICS (stock code BATT80) however it is a standard type and compatible units are available worldwide from a number of manufacturers. Nominally measuring 54.9mm high, 97.3mm long and 25.5mm deep the battery is 6 volts with 1.2Ah capacity. The table below lists the stock codes of a number of manufacturers and stockists.
