Subaru Liberty Batteries

Heat and vibration are the most harmful elements to an automobile battery. However, many other factors can cause failure, such as: corroded cables and terminals, lack of electrolyte maintenance, sulfating, alternator/regulator malfunction, and electric shorts.

If a battery was discharged quickly then it should be recharged quickly, and a slowly discharged battery should be recharged slowly. The main concern is to not overheat nor overcharge the battery.

All batteries contain sulfuric acid and can generate explosive gases. Read and follow all warning labels before charging a battery. Be sure to charge in a well-ventilated area.

It is important to follow the charging instructions to ensure that the battery is returned to a full charge as battery chargers vary by manufacturer. For best results, charge the battery as soon as you know it is discharged.

AGM and Gel batteries require lower charging rates compared to regular flooded lead-acid varieties, and are usually charged at constant voltage.  

Warning: Once a battery has been fully charged, it should be disconnected from the charger immediately. Continuing to charge a fully charged battery will severely damage the internal plates and shorten battery life.

When a battery is discharged (flattened), the car’s alternator will try to recharge it as best it can. This added load on the engine will use more fuel

We recommend against adding any additives not authorised by SuperCharge as they may cause impurities and may be detrimental to your battery. You should, however, add water only to accessible battery types, which require regular topping up. Remember to use distilled water only and be careful not to overfill.
