  BC4 battery analyser


The BC4 single battery analyser makes it possible not only to recharge batteries used in the SE4 family of 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 BC4 and left there until the time comes to use it. However, the BC4 can also provide additional information about the ‘health’ of the battery, so the user can determine the battery’s ability to power the respirator.

  
 
BC4
  

The S.E.A. battery rests snugly in the cradle while the BC4 takes care of a number of procedures, all working to bring the battery to top condition and keep it there.

The battery can be left in this position for long periods. The BC4 re-conditions it every 30 days.
