Learning How To Manage Batteries
Not long ago we put into service an Opus BT-C3100 V2.2 Smart Charger which handles AAA, AA, Ni-MH, NiCd and Lithium Ion batteries.
We'd been hobbling along on a few re-chargeable AA batteries for awhile, and after viewing many YouTube videos on the subject, decided on this charger.
To prove that it will do what is claimed took a few months, but it works as advertised.
4 Radio Shack AA re-chargeables had lost most of their capacity due to age and the ravages of the dumb charger we were using. By following the instructions, we have been able to revive and continuingly improve these batteries to the point where they are back in shape doing serious jobs.
The unit discharges down to the lower limit, 0.9V, recharges to the top, then repeats the process a total of 3-times. At the end the LCD displays the mAh and every time we go through the procedure the batteries show a higher capacity.
Another situation occurred when batteries powering a portable radio were drained down to 0V, below the minimum recognized by the charger, and the charger refused to recognize the batteries.
To the rescue comes a video on YouTube showing how to recover a completely spent rechargeable battery.
To test the trick I built a simple battery pack containing two charged batteries in series yielding an output of 3V, placed the leads across the contacts of the zeroed battery for about 2-seconds, three-times in a row, which re-excites the dead battery just enough to be recognized by the charger and the battery is good again.
Now we're looking for smart chargers for C and D batteries, but see nothing so far.
