How to spot a Genuine Warranty

Due to the technical and manufacturing standards of GS batteries, the rate of genuine manufacturing faults is negligible and is often due to:

• SHORT CIRCUIT/DEAD CELL

Typically seen in a battery within a 12-month service life. One cell will show a dramatically lower acid specific gravity reading than the others. All other remaining cells will show a good specific gravity reading of 1.26 or above.

• INTERNAL BREAK

The battery will have good specific gravity but no voltage reading. Check for any physical damage which may have caused an internal break.

There are many different types of digital testers on the market. They generally give a good indication of problems but are NOT a reliable method of checking the performance of a NEW Battery, only FAULTY OR USED batteries.. Different makes of tester and even different models, can give different results. In addition, the display results given when testing a battery can vary widely. Our testers have a ‘warranty’ testing function which uses specific testing criteria giving a more comprehensive result.
