Battery Delta DTM1240 L, 12 V, 40 A/h

Use the lead-acid battery Delta DTM1240 L for the uninterrupted operation of devices connected to it in low-current systems. It guarantees a backup autonomous power supply for disorders in the mains.

Advantages:

• AGM technology production provides high energy density and low self -discharge rate;
• a large degree of gas recombination (99 %) guarantees small discharge;
• A sealed design excludes the possibility of electrolyte leakage;
• safety valves reset excess pressure that occurs inside the battery;
• does not require maintenance and control of the level of electrolyte;
• meets the requirements of UL, IEC, GOST P;
• The battery housing is made of ABS plastic, which does not support burning;
• Pig plates alloyed with calcium provide low self -discharge and high constructive grill strength;
• The service life is 12 years;
• There are no restrictions during air transportation.

it is used as a source of uninterrupted nutrition in the organization of security and fire alarms, telecommunication systems, as well as for medical and other equipment.
