Recent advances in battery technology means that there are a variety of different formats available when looking for a sealed 12 volt deep cycle battery.

An AGM ( Absorbed Glass Matt) deep cycle battery features the electrolyte suspended within porous fibre mat separators. This is a sealed design which eliminates the potential for acid spills or leaks, and electrolyte levels within the battery never need topping up.

Gel batteries are a different type of battery that utilise gel electrolyte technology where the battery plates are held securely in place in an immobilized gel.  This format is a robust design and resistant to spill.

The premium deep cycle batteries manufactured by Deep Cycle Systems use a proprietary range of DCS 3.2V cyclindrical cells comprising lithium phosphate energy storage in a sealed battery system. They are one of the safest lithium cells available and offer superior cyclic performance specifically engineered for deep cycle applications.

A sealed 12v deep cycle battery from Deep Cycle Systems is designed to be cycled (discharged and recharged) numerous times, which means it will provide power at a steady rate over a long period of time.

Upgrading to a DCS lithium battery is a simple task as it takes up approximately the same space as a conventional battery, yet offers six times the battery life and less than half the weight of a other batteries on the market.

Key features of our sealed 12v deep cycle battery are:

·         Extreme vibration resistance

·         Long service life

·         Made from flame retardant ABS Plastic

·         Manufactured to ISO 9001 Quality Assurance Standards

·         Low weight, high performance , and renowned reliability.

When failure is not an option, look no further than a sealed 12 volt deep cycle battery from Deep Cycle Systems.
