Do you know how long that set of batteries will really last?? Is that battery still good?? Will this battery take a charge at all?? Answer those questions and take control of your batteries with the BT-C2400. How long will this set of batteries last in my device?? The BT-C2400 will test your cells for actual capacity, not just what is printed on the label. This charger will actually put your batteries through a charge/test cycle and then display exactly their tested capacity. No more guessing how good those batteries are. You can then use that information to put together groups of closely matched cells to get the run time that you expect. Is this battery any good?? Will this battery take a charge at all?? Use the BT-C2400 to run it through a charge/test cycle. Find out for sure. Test internal resistance to see if it can handle the load current. If the cell does test below expectations you can then run it through a discharge-refresh cycle to try and bring it back to life. This can happen when NiMH cells sit unused for an extended period. Due to self discharge they can become completely depleted. It may take several cycles to bring them back to life. No problem, the BT-C2400 does that with ease for AA AAA cells.
