This heavy duty AGM battery is the perfect option for the use in Caravans, Motor homes, Camper trailers or even as a second under bonnet battery.
The Redback Extreme takes the technology of an AGM battery to a whole new level! Built with heavier internal lead plates, this battery is designed for continual discharge for heavy draw appliances. Its bonded element design allows for strength against corrugated or rough terrain, making it vibration resistant and the perfect choice for an off – road battery!
Whilst the Redback Extreme is not designed as a primary cranking battery (like the Thumper Redback hybrid), it does still hold the capacity to start up to a 10Lt diesel engine. The Extreme is designed as a secondary battery rather than a primary starting battery. The perfect combination for an under bonnet dual battery system would encompass the Thumper Redback (either 105 Ah or 120 Ah) as the starter battery and the Redback Extreme (either 105 Ah or 120 Ah) as the secondary battery.
Due to design of the heavier internal plates within the Extreme battery, it allows for rapid discharge and recharge of heavy draw appliances to be continually used.
Due to the internal characteristics of the battery, the Redback Extreme will allow for longer life over that of a standard AGM battery.

Great service and delivery was on time
I've purchased 6 previous batteries since 2010. This is the first replacement battery. All of the others have been moved on with the camper trailer or boat they were installed in. This replaced a 2014 purchased battery.
