Servicing and operation of lead-acid batteries | Controls and indicators |
CAUTION
Lead-acid batteries are to be charged immediately after use. Discharged lead-acid batteries are to be charged for approximately 16 hours at 1/10 of the rated capacity.
A few basic rules need to be observed in the handling of lead-acid batte- ries, to maintain their service life over several years.
Lead-acid batteries should never be exhaustively discharged, i.e. collapse of the cell voltage must be absolutely avoided. A sudden progressive process of decay starts in the inside of the lead-acid battery immediately the charge is completely exhausted. With so-called starter batteries this can lead to complete destruction after just a few hours. A lead-acid battery which has been largely discharged must therefore be recharged without delay. It is best if lead-acid batteries retain a certain residual charge and are then immediately recharged to their rated capa- city.
The manufacturers of lead-acid batteries also recommend that lead-acid batteries which are not in use should pass through a complete dischar- ge/charge cycle once a month in order retain the capacity.
The VHF RT unit in the cabinet contains a voltage monitoring facility. If the operating voltage drops below 10.5 V, the frequency display begins to flash. When operating with a lead-acid battery, this is a signal to immediately recharge the battery.
