+ | * Check battery voltage for each battery separately when fully charged. Fully charged the total open circuit voltage should be above 12.6 V (2.1 V per cell). | ||
+ | * A fully charged battery voltage around 10 V indicates a dead cell and battery needs replacement | ||
+ | * Check condition of the battery poles and connectors. They should be kept clean for good electrical conduction. | ||
+ | * Check that the 3 battery cables are not damaged | ||
