Care
Sometimes the battery may appear flat, but this could simply be dirty or loose connections on
your battery terminals. It is important to maintain the leads on a regular basis. Do this by
removing the leads from the battery, clean the inside of each connector and terminal posts on
the battery, smear the terminal posts and connectors with Vaseline, refit in their correct
positions and tighten firmly.
It is essential to keep the electrolyte level above the plates.
Note, however, that you should not overfill it, as the electrolyte is strongly acidic. When
topping up do not use tap water. Always use distilled or de-ionized water. It is important to
keep the acid level up. If necessary, have it checked by a battery specialist.
Checking the condition of your battery
Using a hydrometer, which can be purchased, from most motor accessory stores, you can
check the specific gravity of the electrolyte in each cell. The hydrometer is use to suck up a
quantity of fluid from the cell. The weighted float inside the hydrometer will register the
condition of that cell. Put the fluid back into the cell after testing, taking care not to splash the
fluid about.
