EnerSys Inc. is the world's largest provider of stored energy systems, bringing together the combined experience of long-established brands such as Hawker, Exide and General Battery. It offers a broad range of batteries for military and civilian applications.
Central to the EnerSys defence and security markets are its technically-advanced sealed lead-acid batteries. These are true "maintenance-free" batteries offering exceptional electrical performance and unrestricted transportation by land, sea or air. They use recombination electrolyte (RE), absorbed glass mat (AGM) and pure lead grid technologies.
RE technology allows zero maintenance by ensuring that the oxygen given off at the positive plate during charging is recombined with hydrogen through reaction at the negative plate to form water so that the electrolyte is continuously replenished. AGM technology uses microporous glass fibre separators to absorb all the electrolyte so that there is no risk of leaks or spills and batteries can be transported safely as components, or already installed in military vehicles.
The batteries offer exceptional electrical performance under a variety of operating conditions, from prolonged heavy discharge during engine starting to the long, continuous drain of "silent watch" duty. They can be stored fully charged for up to two years in temperatures up to 25Â°C and then brought into service, frequently without recharging. They also offer exceptional recovery from deep discharge (when the battery has been discharged completely).
They are suitable as direct replacements (electrically and mechanically) for other types of battery and are suitable for use in a wide range of temperatures from â€“30Â°C to +40Â°C continuous duty.
The excellent performance and deep discharge capabilities of pure lead plate technology are available in Odyssey batteries which are intended for general automotive use, and applications involving heavy (high power) short discharges.
