DA Series Lead-Acid Maintenance-Free Battery

The DA series maintenance-free lead-acid batteries primarily include various models of AGM valve-regulated sealed lead-acid batteries, GEL valve-regulated sealed lead-acid batteries, and tubular plate lead-acid batteries such as OPzV, OPzS, PzB, PzS, and PzV types. Based on voltage classification, the product types are mainly divided into two series: 12V and 2V. The 12V series offers capacities ranging from 24Ah to 250Ah, while the 2V series ranges from 100Ah to 3000Ah. All products in this series strictly comply with national and industry standards such as GB/T 19638.2-2005, YD/T 799-2010, and DL/T 637-1997. These batteries feature flexible installation in any orientation, low self-discharge, high gas recombination efficiency, excellent tolerance to overcharging and deep discharging, and long service life. They are mainly used in applications such as UPS (Uninterruptible Power Supply) systems, backup power for communication systems, power system control power supplies, office automation systems, marine lighting and signaling systems, fire alarm and security systems, among others. Custom installation racks can be designed as needed. Users can choose different capacities and specifications according to equipment load and usage conditions.
