Overview:

The Dongjin DJ12V-70Ah Dry Battery is a sealed, maintenance-free VRLA (Valve-Regulated Lead-Acid) battery rated at 12V nominal with 70Ah of capacity, built for mid-size UPS, telecom and solar backup applications. Being sealed AGM construction, it needs no water top-up over its service life and can be mounted in various orientations without electrolyte spillage risk.

Float charging voltage is specified at 13.50–13.80V (or 13.60–13.80V on smaller models) with a -18mV/℃ temperature compensation factor — meaning the ideal float voltage adjusts slightly as ambient temperature changes, a standard VRLA design detail that keeps the battery from being overcharged in hot weather or undercharged in cold. The battery is rated for a nominal operating temperature of 25℃±3℃ (77℉±5℉), with a wider tolerance band across charge, discharge and storage conditions.

Terminal type is T5/T9, with copper terminal material for reliable conductivity, and the unit weighs 21.5kg. It’s rated for a 10–15 year designed floating life, longer than the standard warranty terms on smaller units in the range, reflecting the more robust plate construction typical of mid-capacity VRLA batteries designed for standby duty.
