			The battery is, of course, what drives the SE400 respirator. It is important to take care of the batteries, to recharge them in the correct way, and to keep them in peak condition at all times. Batteries can be used in several configurations, and battery management systems are available to keep a large number of batteries in optimum shape. The SE400 battery management system (known as "BattMan", also as GBCO for Gang Battery COnditioner) lets you store, manage and condition up to 28 batteries at the same time. The system is ideal for long-term storage of batteries. Batteries are drained, recharged and conditioned automatically from a single powerpoint.

Updated features (Aug 2011)

The GBCO now detects battery charge level when a battery is installed or after the unit is powered up. When a highly charged battery is encountered, the GBCO applies only a short post-trickle charge, rather than a full charge cycle. This dramatically reduces the time for a fully laden GBCO to fully recover after a power interruption – from about 6 days to about 8-12 hours.

Some operations can now be performed simultaneously on multiple batteries – the GBCO can now charge one, discharge one and post-trickle charge two batteries simultaneously. This dramatically reduces the time to process all batteries – a complete discharge-charge cycle is reduced from 12 to 5 days, while a complete charge-only cycle is reduced from about 7 days to about 12-48 hours.

There is a new diagnostics display that shows a wide range of information about the batteries and their condition.

There is improved fault management for the GBCO and the batteries it manages. An extended error menu is available, plus comprehensive engineering information to assist with technical support.

An integrated self-test has been added to assist with technical support.

The GBCO now rejects faulty batteries that cannot be charged, and will report an error. However, the BC4 should be used to fully assess battery condition.

An audible alarm has been added to augment the visual warnings.

Future firmware upgrades and new features can now be implemented without dismantling the GBCO.

Current-management, power connections and ventilation have been improved to further enhance reliability. Current-monitoring features have been added to enhance the already high levels of fail-safety.
