The CSB lead batteries are lead-acid batteries in AGM technology regulated by a valve, even if commonly called hermetic. The GPL series has been designed for a "standby" application with an expected life of 8 years (EUROBAT 6 - 9 years). Complies with the European directive IEC61056-1 / 2.For correct battery operation it is necessary to follow some instructions.CHARGE: the charge must be made with a constant voltage battery charger, strictly following the data on the battery. Incorrect voltage can lead to the immediate deterioration of the battery itself.DOWNLOAD: must not be brought, during the discharge phase, to a voltage lower than 10.50Volt for a 12Volt battery.It must not be left unloaded after its use, but must be refilled immediately.CAUTION: The battery contains sulfuric acid. Pay attention when it is manipulated. In case of accidental contact with the acid, do not touch the eyes or the mouth. Wash immediately with running water and go to the hospital emergency room.The battery must be disposed of according to current regulations Voltage: 12 VCapacity: 12.0 AhStandard charge current: max. 1/3 of the capacityBuffer charge voltage: 13.5 - 13.8 VCharge voltage for cyclic use: 14.5 - 14.7 VDimensions: W x D x H - HT: 151 x 98 x 100.5 mmTerminals: 6.3mm FastonWeight: 4.10 Kg
