Examine the label on the battery showing the check intervals in order to determine when to test the voltage.

Charge the battery if the open circuit voltage is lower than 12.8 V. Leaving the battery discharged for more than one month could damage it. Check the battery charge with a voltmeter.
Always check the condition of the battery before recharging and 1 to 2 hours afterwards.
Important
Pay careful attention to recharging times. Stop charging immediately if the battery becomes too hot to the touch. Leave to cool before resuming charging.
Use only constant-voltage battery chargers.
Check that battery terminals are properly connected to the battery charger.
To charge the battery, proceed as follows.

Use fast charging in emergencies only.
Storing the battery
If the battery voltage is less than or equal to 11.5 V, it must be recharged.
Connect the battery charger to the battery.
Use a voltage of 16-17 v.
If the ammeter shows no change, increase the voltage to the maximum of 25 v.
Charge for 5 minutes.
If the ammeter shows a change, return the voltage to 16-17 v; otherwise replace the battery.
