HBL Battle Ready batteries employ Pure Lead Thin plate technology for high performance. These Valve Regulated Lead Acid, maintenance free batteries are designed using Absorbent Glass Mat (AGM) separators. The use of AGM separators in combination with self-resealing, pressure-regulating valves and a starved electrolyte design enables recombination of gasses generated during normal operation. This eliminates free acid and the need for electrolyte top-up. These batteries are tested for vibration & shocks. Battle Ready batteries are delivered fully charged and are ready for use.
