Since 1985 Accu Oerlikon has been developing and producing, under
ISO 9001/14001 certification, a full range of VRLA cells and monoblocs specifically for applications where a high reliability, long life (up to 15 years) and a solid engineered design are required.

The capacities covered by the actual Compact-Power™ series range are from 12 V 25 Ah (C₁₀) monobloc to a 2 V 3000 Ah (C₁₀) cell. As its name suggests, Compact-Power cells and monoblocs are maintenance free, smaller and lighter than conventional flooded stationary batteries and are capable of delivering very high discharge currents. In addition, a tightly boxed component assembly imparts excellent resistance against shock and vibration. The cells and monoblocs are supplied ready to install, with no acid or water additions whole life long and no expensive special battery rooms.
