TOPPING UP
During the course of normal operation, the batteries should be inspected at least once a fortnight to
check the level of electrolyte. During the end of charge, gassing takes place, which will cause a slight
reduction in the volume of acid in the battery. This can be topped up with de-ionised water as required.
During this inspection, it is useful to note any imbalance in the fluid levels. One indication of a faulty
cell would be an increase in the loss of battery acid, which would then require more frequent topping
up on that cell, or cells. Faulty cells can liberate excess hydrogen, even during normal operation, with
the resulting risk of explosion if ignited.
Any faulty batteries should be replaced as soon as
possible with an equivalent sized and rated unit.
Note: BATTERIES CONTAIN ACID, therefore: - protective safety glasses and gloves
(Appropriate PPE) MUST be worn whilst performing these checks.
