Once the engine is running, the battery is no longer required to perform any function and the engine charging system replenishes any electrical energy used. It is always advisable to fit a battery with the highest possible Cold Cranking Amps (CCA) available as this will help ensure the engine starts in cold weather conditions. It should also be kept at the highest state of charge possible.
If the canal boat sits unused for extended periods of time throughout the year, this puts a considerable strain on the battery and can dramatically reduce its life if not properly maintained. It is important to keep the battery fully charged when not in use whilst ensuring never to over-charge it as this can cause permanent damage.
- Avoid fully discharging the battery as this damages its ability to return to a fully charged state
- Always re-charge immediately after use, keeping the battery in as high a state of charge as possible
- If not being used for long periods of times, regularly check
the voltage and give a refresh charge where required
(approx after 3 months) – taking care not to over charge
- Store batteries upright in a cool, dry and well-ventilated area
- Keep the battery and terminals clean and dust free
- Regularly check the electrolyte levels, topping up only
with de-ionised water when necessary
- If you keep spare batteries, remember to rotate their use
- Regularly inspect all connectors, wires and other aspects
of the vehicle’s electrical system for faults
- Please note – although the SD range of batteries are
sealed, a breather tube should still be fitted
- For extra peace of mind, you should consider taking
a spare back up battery.
