VARTA Professional Li-Ion Deep Cycle Batteries

The Li-Ion Deep Cycle range is VARTA's lithium service battery. It does not start engines: its function is to power on-board consumption with deep daily discharges.

Technology

Uses LiFePO4 chemistry, the most stable and safe lithium variant for leisure installations. Compared to an equivalent lead battery, it weighs around 60% less and takes up less space, allows thousands of cycles instead of hundreds, and enables almost the full nominal capacity to be used, while with lead it is advisable not to go below 50%. Integrates a BMS that protects against overloading, deep discharge, short circuit and out-of-range temperatures.

Applications

• Service battery for recreational boats
• Motorhomes and campers with daily consumption
• Isolated solar installations
• Auxiliary equipment that discharge and recharge daily

How to choose

You need a lithium charger: a lead charger does not complete the charge well and may activate the BMS protection. Also check that the alternator or solar regulator are compatible before replacing a lead battery.

Naming and equivalences

Professional Li-Ion Deep Cycle is a new range in the VARTA catalog, without equivalent in the previous nomenclature. It is a lithium LiFePO4 service bank and does not replace any starting battery.
