10. Batteries
The systems on your yacht are all 12volt. The batteries will need to be
recharged as often as you deplete them. Conserving power will result in less
time needed for charging, so turn off systems that you are not using.
Your batteries will charge when the engine is running at 1400rpms or more
whether sitting at a mooring or motoring to a destination, or when the
generator is running. Check the battery levels and make note of them before
charging.
Run the engines at 1400rpms or more (or the generator) for a minimum of
1-1 1/2hrs twice daily.
.
Shut the motor off. Wait 15 minutes before checking the battery levels,
(directly after turning off the motor they will remain in an excited state for
about 10 minutes).
The House system should come to rest at 12.8 v. and then slowly get lower.
When the system gets to 12.2 you should start planning to re-charge the
batteries soon.
Maple Cookie’s house battery bank is isolated from the engine start battery
and the house battery’s have a capacity of 430Ahrs
The batteries are located in the stbd eng compartment. They do not require
any checks whilst on charter.
