 Topic: Replacement DeWALT Battery?
Posted: 26 Nov 2023 at 5:25pm |
I got a big adz DeWalt cordless drill that looks and runs like new. However the 18v XRP battery is going south. The other one that came with the package retired some time ago.
I am not gonna experiment inside the batt. Is there a wand to wave over this sucker?
If not, where is the place to get the best bang for the buck on a replacement battery.
thanx

I've always recelled them myself reutilizing the original case. A high wattage soldering iron really is the only tool needed to weld the tabs onto the cells. Some replacement cells come with them installed too.
My 14.4VXRP series is getting weak again after about 20 years use but the clutch is shot also so probably will pitch it this time.

I dont know if you use Lithium or Ni-Cd batteries( depends on your charger).. and if you use the 4 - 5- 6 amp batteries .......... but i have had good luck with Aftermarket batteries in my 19.2 Craftsman.. Normally last about 4 years.. I buy a pair every 2 years..
I look for ones that have high star ratings by users.... something like this on Amazon.

They make a 20v adapter. Works good but need a 20v charger and batteries

I've batteries my B&Ds with lithium batteries just search for lithium replacements I got mine from Amazon had to buy a new charger but they fit just like originals last more the twice as long and have more power. Since I have a half dozen tools that take the same battery it was well worth it to change over. They also have battery adapters for dewalt that use new 20 volts on your old tools if you already have 20 volts that's the way to go.

I agree with Dave.. My Craftsman set is old enough that it came with Ni-Cad batteries and charger. About 10 years ago i bought a couple Lithium Batteries and a new charger for them. ... Now i have 3 chargers and keep 4 batteries up.. all 5 or 6 amp Lithium.

My DeWalt units have made it thru three battery replacements and one set of Battery Plus Rebuilds(They lasted longest). Bat+ is no longer around here so lost that access, they also did NOT work LiIon units. Think I may change up to Milwaukee next round as heard Good things on their tools. My DeWalts are worn Slick.

The DeWalt batteries are not cheap and not guaranteed. But I have lots of cordless tools. So I have switched them all to 20 Volt with the adapters. and or the new ones are all 20 volt. I think I have four chargers, and maybe 8 batteries. I would like to see how to refurb these. (Codgers post above) Regards, Chris and Cheryl

If your buying Factory Milwaukee batteries and paying $100. each, you might save $$ by rebuilding with new individual batteries and soldering together..
If your comparing to Dewalt or Craftsman aftermarket that cost $30. each... you are probably further ahead to buy NEW .... Also, its not just the "battery" that can fail. Most of these new units have a small circuit board and a few little "other parts" that might fail.

Buddy at work has the adapter to run the newer 20V lithium batteries in his old 18V Dewalts. I think that's the way to go if you have a bunch of older 18V tools that are still in good shape, and just move the adapter around as needed.
Otherwise, even though it seems dumb to waste a perfectly good 18V drill... If that's all you have, it might end up being cheaper or the same price to get a new 20V drill + battery + charger kit, when compared to buying just batteries, charger, and adapter to use in your old drill. Now if it's one of the bigger, more expensive models then the adapter route may still be cheaper.
The pricing on the drill + battery + charger kits are such that you can catch them for about as cheap, and sometimes cheaper, than just the batteries and charger. There are way more likely to be sales and promotions (like get an extra battery for free) on the new drill kits.

Buying the drill / battery combo on sale is a good idea compared to just a battery, IF thats all you need... I have a skill saw, recip saw, grinder, drill, impact and a couple flashlights that all use the same battery .. Bought the 7 tool "KIT" maybe 20 years ago.. No advantage to me to change to 20v with adaptor.. WHY ? I can get 19.2 v batteries for the same price or cheaper. Adaptor is fine if you have multiple Manufactures of tools.

Steve, I think the other reasons to get the adapter and go with up to date lithium OEM Dewalt batteries (in the OP's case) are that they are readily available (in case you manage to destroy one and need a same day replacement from a local store), ability to buy new tools using same batteries, and the longevity of the new batteries.
I have 5 Dewalt 20V lithium batteries ranging from 2-5 Ah that are all 6+ years old, and all of them still hold charge well enough that I can't tell that any of them have degraded. Don't get me wrong - I'm not recharging them 3x every day putting up pole barns for a living, but if I don't use a battery for a month or two in my rotation, it's still ready to go. I have always heard that big OEMs like Milwaukee, Dewalt, etc. get the cream of the crop when it comes to the battery components from Panasonic, etc. and the leftovers that don't meet their quality requirements are what get sold to the open market. I don't know if there's any truth to that.
And if I need a new tool for a specific job, I can pick one up and it uses the same batteries because they are current.
Just things for the OP to think about. If the knockoff Amazon 18V batteries have good reviews, it may be worth a gamble if all you want to do is keep this one drill going for a few more years. That would be the cheapest option. Personally I'd be thinking about the other pluses to making the investment in an adapter and 20V lithium batteries, or a complete new drill kit if cheaper.
Also, Christmas is coming up!
