Description
Single battery care & recharge
The BC4 single battery analyser makes it possible not only to recharge batteries used in the SEshield respirators, but also to ascertain the current status of the battery, as well as maintaining the battery in peak condition over long periods of time. Essentially, a battery can be placed in the analyser and left there until the time comes to use it. However, the unit can also provide additional information about the ‘health’ of the battery, so the user can determine the battery’s ability to power the respirator.
