General recommendations for battery operation and maintenance
There is no such thing as a "maintenance-free" technical product. In cases
where regular maintenance is not guaranteed it is better to choose a Valve
Regulated Lead Acid battery (VRLA). In cases where regular maintenance (once
every six months) is guaranteed, the vented battery is a good choice.
-
For vented batteries the electrolyte levels should be topped up to the maximum
level indication at every maintenance interval. Distilled (or deionised or
demineralised) water must be used for this. Using ordinary tap water will
reduce the lifetime of the battery considerably and this damage cannot be
repaired. If possible allow for full recharge after topping up with water.
-
Never add acid to the battery.
-
Keep the battery clean and dry.
-
Terminals should be kept clean and connected tightly to the leads.
Anti-corrosion materials can be used to protect battery terminals and leads.
-
Make all attempts to keep the battery within the temperature range as specified
by the manufacturer.
-
Batteries should be kept in a thermally insulated location whenever the ambient
temperatures may go above 30°C frequently and/or there is a risk of
temperatures below 0ºC. Batteries should always be protected from direct solar
radiation or other heat sources. For example batteries can be placed in
insulated containers buried in the ground.
-
Even a stored new battery will lose charge due to self-discharge. Store the
battery in a cool place and recharge it once every three months for flooded
types and once every six months for VRLA.
