Each Thumper unit consists of multiple 12 Volt AGM cells (Absorbed Glass Matt) linked together in parallel.

The cells are maintenance free and will not leak or gas when charging; perfect for use inside the vehicle or enclosed areas.

Unlike other batteries on the market, the Thumper range of batteries hold a very low internal resistance, resulting in the ability to charge at a rapid rate and reach fully charged within 2 – 3 hours of vehicle charging.

The Thumper battery is classified as our “hybrid battery”. Due to the way in which this battery is designed, it allows for the battery to be not only be used as a deep cycle battery, but also as a cranking battery.

Replacement 48AH Thumper

Great although my original purchase was a replacement battery set for my old Thumper but due to the VPN showing I was more 1000kms from the delivery address that did not go through. However, now have a new Red Thumper with extra features that fits exactly where the old one did so very happy. Engel car fridge will now work all the time.

Replacement batteries pack

I have bought a fridge Thumper 10/15 years ago and needed news batteries. Order them to 12 Volts and in no time receive them in Mansfield Victoria. Fantastic! 1st classe company. Highly recommended. In no time with the replacement manual my old Thumper was up to work again!!! Thanks Alain
