Delta HR12-4.5, 12 V, 4.5 A/h battery

Use the lead-acid battery Delta HR12-4.5 to ensure uninterrupted operation of devices connected to it in low-current systems. It guarantees a backup autonomous power supply for disorders on the network.

Functional advantages

• AGM technology production provides greater energy density and small self -discharge speed.
• High degree of recombination (99 %) guarantees low gas production.
• The hermetic design excludes the possibility of electrolyte leakage.
• meets the requirements of UL, IEC, GOST r. /Li>
• does not require maintenance and control of the level of electrolyte.
• Pig plates alloyed with calcium provide low self -discharge and high constructive strength of the grill.

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