- This video is about the process of Reviving a cordless Ni-CD battery from a dead state to a rechargeable state using a 30v Power Supply, so it can be reused on cordless tools. Sorry for the audio changes going in and out. I was going back and forth behind the camera.
I'd rather charge with this u git to chooze your voltige and max current another way to charge a battery is connecting them to higher voltage batterys in parallel and let the voltage difference charge the battery. the bigger the voltage difference the more current
Yes Matt, that is the next thing I will try using another fully charged battery and connect them in parallel to see if it will wake up and take more charge.
Best read the reviews on the cheap replacements on Amazon before parting with money.
The audio is terrible unfortunately.
I have a clansman radio battery (24v 4ah), I know i got to charge is 10% of the amp hour rating, so 0.4amp, but what would the voltage be for a slow charge? its a nickel metal hydride battery. I also have a small 12v 0.6ah battery for a smaller radio so a 0.06amp but again what voltage? would it even charge from this particular power supply?
Harry, to ensure that your batteries get the proper charge, I would recommend a charger that has multiple amp settings with a one amp or lower setting. This power supply is made to provide a constant state of current and voltage for the load that is using it. A charger changes the state of charging as the battery becomes fully charged.
Thanks for the reply and I have been looking at different types of chargers but have no clue on what to get as I would need small crocodile clips to attach to it. and the chargers used in the military fry the battery because they are designed to charge it as quick as possible in the field.
All of this just to save the $17 on a new one? Wow! Not worth my time and effort! Just buy a new one, man! Jeez! LoL!
The question of whether it's worth it or not depends on your particular case. For example I am trying to rejuvenate an old Ni-Cd battery for a restored 386SX laptop from 1990. In my case the battery is irreplaceable, so this video was very helpful for me.
@@kosztaz87 You can still buy the old 18650 cells as they are still pretty common. I'm sure some eBay sellers have them or Aliexpress just to name a few places.
@@buddysteve5543 It's a different chemistry. The laptop's charge circuitry was designed for Ni-Cd battery. It even has a buit in discharge utility in the ROM. Needless to say it would destroy a Li-ion battery, as those have very different charge/discharge characteristics.
vey worth it as toll works right ten wile one get a 2nd battery i assume
