Features and innovations

AUNISOLBAT batteries 12ET-L series are used specifically for the inverters, rectifiers battery chargers and central sources of security lighting. The tight construction of the battery allows operation without problems in all positions. Since No specific maintenance and servicing is required with an operation based on the principle of the gas recombination (99%). The latest innovations allow you to use these batteries in both floating or cycling without reducing its service life or ability. In addition the ABS tray provides robustness with resistance to shock, vibration, chemicals and heat. Our batteries are declared not dangerous by the FFA and IATA.

Temperature compensation of load

To preserve the long life of our batteries, it is advisable to compensate the charge voltage in floating to room temperature. The focus is to 2.275V / cell and 20 ° C, we recommend - 3 mV / ° C for temperatures above 25 ° C and + 3 mV / ° C for temperatures below 15 ° C. It will be necessary to add the optional temperature probe and to  placed it close to the batteries.

Load specifications

Floating - The optimum float voltage for a battery depends on the temperature; between 15 and 24 ° C, the recommended value is between 2,27 and 2,30V. It is recommended to install the batteries in a room or the temperature is regulated, knowing that the float voltage can be increased or decreased to compensate the temperature variations. The setting is +/- 3 mV per ° C.
