DP12-12 12V 12Ah Sealed Lead Acid Battery VRLA AGM F2 Terminal

Valve-Regulated Backup Battery

The DP12-12 battery is a 12V 12Ah sealed lead acid block built on absorbed glass mat technology. It delivers 144Wh of stored energy for UPS systems, alarm panels, access control and small solar installations. A maintenance-free VRLA design recombines gas internally and requires no water topping.

The case measures approximately 151 x 98 x 95mm, and height including terminals reaches about 101mm. Net weight sits near 3.3kg to 3.9kg depending on the production batch. F2 Faston tabs accept 6.35mm spade connectors, which suit standard UPS harnesses and alarm leads. The ABS housing meets flame-retardant requirements for indoor equipment enclosures.

Float charging holds 13.6V to 13.8V at 25°C, while cyclic charging runs 14.5V to 14.9V. Internal resistance measures roughly 13mΩ to 18mΩ on a fresh cell, which supports short high-current discharges. Maximum discharge current reaches 180A for 5 seconds, enough to ride through UPS transfer events. Design life spans 5 years in float service and up to 1,200 cycles at 30% depth of discharge.

The battery operates in any orientation except continuous upside-down service. Self-discharge stays low enough for 6-month storage at 25°C before a refresh charge. Terminals resist corrosion during standby duty in telecom cabinets, security panels and renewable energy buffers. Spade connectors seat firmly without soldering, which speeds replacement in the field.
