Datasheet of 12 volt Sealed lead acid batteries
1. Do not connect and avoid accidentally connection between positive and negative pole with
metallic conductor to avoid short circut.
2. Avoid convert connection or unstable connection.
3. Do not fill unqualified electrolyte or water.
4. Do not operate under insufficient electronlyte condition semi miantenance free battery.
5. Do not using in the Deep cycle(capacity lower than 50% electrolyte gravity,lelow 1.2g/ml).
6. Keep safe vent-valve work properly to avid explosion cause by valve failure.
7. Do not invert or incline more than 45 during transfer or storing.
8. Keep ventilation during charging,no smoking.
9.Don’t near the hot source and don’t under the sunshine.
10.Don’t charge in the sealed container.
11.No short circuit. It should be addition charge if you don’t use, and single charge per three months, to avoid irreversible sulfating. The battery should be changed when the battery jar broken or the electrolyte omitted, to avoid acid corrosion.
12.Don’t store in the space of acid gas. You should be careful and regular check when use the battery. To avoid the battery don’t work. You should change the battery if the capacity is not full or has been damage, especially after one year using.
