How to extend battery life in Ni Cad batteries.

If you still have some of the older Ni Cad battery tools and you are not getting very long life between charges, try this trick. Put your batteries in a bag or container that you can seal, and stick them in your freezer for 3 to 4 days and them pull them out and let them warm up to room temperature before you re-charge them. This is only a short term solution and does not work all of the time but I have seen it successful on many different brands of tools. Hope this helps!

can you use 18v lithium battery in old 18v drill


Yes you can. On tools, 18 volts is 18 volts. Tools don't 'know' how the power is being created, either by Ni-Cad or Li-Ion means. Chargers are totally different. Most Li-Ion chargers can charge older Ni-Cad and some Ni-MH batteries but older Ni-Cad chargers will charge Li-Ion battery untill they overheat and sometimes start on fire because older chargers can't detect when the Li-Ion batteries are full.

I just bought the Lithium - ion batteries for replacement for my 18.0 volt ni-cad battery. when I put it (ion battery) in the charger (ni-cad charger) no lights come on. what's up?


Lithium Ion batteries don't charge the same way ni-cads or ni-mh do. You need a lithium ion specific charger to charge them. (Some chargers do multiple types.)

How do I change the Battery in My Norelco T3000 Beard Trimer


Remove Phillips head screw at bottom of trimmer. Separate body in two being careful to notice how on/off switch is assembled. Unsolder the ni-cad battery from circuit board. Install new ni-cad battery of the same physical size that has solder tabs on it and solder it to the circuit board. I used a ni-hi (nickle metel hydride) instead of ni-cad which had different charging requirements so I limit charge time to no more than 16 hours for a discharged battery. It had been working fine for over a year. Don't forget to apply a few drops of light oil to the cutting blades to extend cutting life. Replacement blades are about $30.00

LCD IS NOT WORKING WHEN CHARGEABLE BATTERIES IS PUT IN THE BP300 GRIP


ni-cad or ni-mh rechargeable batteries all have charging cycle life and will fall in effeciency. in saying that, batteries used for some time will be not be as powerful as the new ones, and over or under charged batteries also wouldn't give you expected power.

i guess the CR123A you replaced is a new one, so it has the desirable voltage and current.

LCD itself and the driver actually do not require a lot of power, but the camera does, which draws away from the battery.
