12V or lower An alternative method of checking the charge level of a battery is using a hydrometer to measure the electrolytes in the cells. The reading should be between 1.1 (discharged) and 1.28 (fully charged).

How many volts is a fully charged leisure battery?

Charging the leisure battery Many are designed to work at a constant voltage of 13.6, to 13.8 volts. This level is carefully chosen to prevent gassing and possible damage to the battery through overcharging. However, it is not enough to give the battery a full charge.

What should a 12v battery read when fully charged?

about 12.6 to 12.8 volts A fully charged battery will typically display a voltmeter reading of about 12.6 to 12.8 volts. If your voltmeter is showing a voltage anywhere between 12.4 and 12.8, that means your battery is in good shape. Any voltage above 12.9 volts is a good indicator that your battery has excessive voltage.

How do I know when my leisure battery is fully charged?

If you are looking at the control panel straight after plugging in the EHU, then yes, a fully charged battery will register 14.3 volts with a current of 5 amps or so. But if the batteries are already full (charged by the alternator) and the charger senses this, the current will fall back to around 0.5 amp very quickly.
