Question about Dewalt 12V XRP Battery Pack

Holding battery charge on 12v DeWalt batteries

I have both 12v and 18v Dewalt drills. The 18V is outstanding, but the 12V will not hold a charge on either battery. I can charge it up and it works fine for a while, but even on a full charge, the next morning it is down...both batteries act the same....the 18v drill holds the charge just fine.

Time to replace the batteries. Some batteries will not last very long. My original ni-cads on a Ryobi lasted only 1yr, and the replacement ones are 2yrs old and are still OK. You might be able to check the manufacturing date on your original batteries and that will give you an idea of how long they sat on the shelf before you started using them. Rechargable batteries have limited shelf life.

That is because of the battery type.  The batteries are nicd Nickel Cadmium and after 24 hours lose a good percentage of their charge.  The Dewalt batteries should be left on the charger, if you read the manual you will discover this is what Dewalt recommends.  It not only does not hurt the batteries it allows the charger to put the batteries through maintenance cycles.

I have read somewhere that running the battery down, and then shorting the battery, putting a wire acrooss +/- termanals. This interrups the recharge memory within the battery.

If this does not work the a cell my be gone and you can get these repaired

Black & Decker Cordless Drill will not charge battery


Either the charging adapter is faulty or the battery is worn out.

If the recharageable battery is more than 3 - 4 years old then the battery could be worn out.Rechargeable batteries have a finite number of charge and discharge cycles andwill lose their charge capacity over time, i.e. won't charge to 100% andgradually the charge reduces until the battery won't charge up at all. OR Thebattery shows a 100% charge but when the adapter is disconnected the batterydrops off to zero capacity in a very short time. If the battery drops to anunacceptable charge level then the battery needs to be replaced.

I do not recommend connecting anything but the factor charger to the battery. No 12v will not not charge an 18v battery.
They can BLOW UP if you apply too much current.
The correct charger can be found cheap. Look on craigs list under tools.
Good Luck

Can you charge ryobi lithium batteries in a regular ryobi charger?


NO! Never charge lithium batteries in a charger designed for nickle based batteries like the NiHi your old charger was meant for. Ryobi did design the new Lithium charger to be backwards compatible so you can charge your older 18V NiHi batteries in the Lithium 18V charger.
Also note, NEVER miss-match the voltage, for example, make sure you are not trying to charge 12V batteries in an 18V charger unless the manufacturer has specifically stated that the charger is capable of multiple voltages.

Try placing the battery in a freezer for six hours before trying to charge the battery and if this doesn't work find a friend with a working charger and make sure using that method that you don't just have a bad charger.

My new drill suddenly stopped working even though the battery has been charged OK.


Is it Nano li-ion? have you got another spare battery to double- check?
I experienced the same problem with 18V Dewalt nano li-ion battery. Was fully charged, came to work- Dead!!! I was lucky I had spare one, so then i was ok, but anyways had to buy a new one. Check on these things:
1. Battery is faulty. If u have any chances to ask someone who has the same gun (voltage is very important!!! has to be the same!!!- 12V battery to 12V gun, 14.4 to 14.4, 18 to 18 etc). Put your battery into that other gun. If You find the same problem that means your battery is dead.
2.Gun with battery contacts. If you 100% sure, that batterIES (check 2 batteries, or more) are OK, check bottom contacts where u put battery in, use WD40, or similar to clean them.
3. Least common Dewalt thing (Most common in Panasonic drills) is trigger contacts.
Basically i do not know what model is your dewalt, i was only talking in general, but there are no miracles- stopped working suddenly, and what u describe new, for instance my new drill dw727kd is less than 1 year old, i was too stuppid to open that battery myself to void warranty :(
AAAAHHH!!!!!! One more thing - If you have not tried to open these screws- check your nearest Dewalt authorised repair center- new NANO batteries have 2year warranty!

I have a 12v xrp cordless drill. in the past 6 months i have purchase 3 new batteries. none will hold a charge. what is the problem.


You may want to try a different charger base. Any way you can borrow one so you don't have to purchase first?
If for some reason the charger isn't working well, you may be getting a partial charge and only that.

You may even want to rent a cordless just to try charging your own battery on a different base.
before you buy.
