Storage batteries are the heart of all off-grid and back-up wind/PV or inverter electrical systems. Their function is to balance the outgoing electrical requirements with the incoming power supply. They offer a reliable source of electricity which can be used when solar or wind power is not available. Batteries are able to provide short term power output many times higher than the charging source output.

Rolls premium deep cycle batteries have earned a reputation of reliability and dependability in the renewable energy markets.
Dual container construction, high-density polyethylene materials and unique "resistox" plate design provide a life expectancy that is among the longest in the battery industry.
These are manufactured to stringent DIN standards (IEC-61427) for the support of PV systems and have an excellent reputation within the European power storage industry. For PV applications with limited depth of discharge the Hoppecke OPzS range can support up to 7500 cycles. They are made with a tubular plate design with a gauntlet that minimises the loss of active material. This combined with the use of recommended acid densities and gas and liquid tight post seals result in a design life of 15 years. Together with the optional AquaGen recombination caps they have extremely long intervals between topping up with water.
The increasing levels of electronic devices found on boats, yachts and motorhomes has led to a greater demand being placed on the batteries installed.
Varta meets these demands by supplying a battery specifically designed to supply motorhomes and marine craft with energy whilst delivering exceptional performance characteristics - The Professional deep cycle range.
Varta’s Professional deep cycle batteries are based on tried and tested flooded technology, the product of years of continuous improvements in cyclic durability.
- Hi cyclic durability
- Suitable for dual power use; starting and deep cycle
- Maintenance free
- Safer to use: can be tilted to 90° for short periods
- Long lasting and durable
- Ideal for seasonal use
These sealed deep cycle batteries use a Gel electrolyte. They are spill-proof, leak-proof, never require watering, and don’t gas during normal charging. They can be mounted inside equipment enclosures. Often used in remote, unattended power systems. Due to their sealed nature it is very important to prevent overcharge & over-discharge. Tapered post terminals. Self Discharge: 1-3% per month Cycle Life: 4000+ cycles to 20% DOD; 2000 cycles to 50% DOD; 1000 cycles to 80% DOD
A range of battery accessories are available including terminals, hydrometers, deionised water etc.
Suitable labelling for battery systems as required by MCS guidelines.
Labels are printed on self adhesive vinyl and are designed to remain legible and in place throughout the design life of the system. Labels are available individually on in sheets of one type.
