Buying a replacement battery for my drill

SDE · Dec 4, 2017

I have a black and Decker HPD1402 cordless drill. The batteries need to be replaced. Some of the replacement batteries are 1500mAh and some are 2000mAh. I do not see anything on the old battery, as to which of these ratings that I should buy. Is the 2000mAh the better battery?

Are they the same physical size? if they are then I would use the 2000 mah. they will take a little longer to charge and last longer in use.

I have no experience with the Black & Decker brand since my first 1/4" cordless from them in 1970. I have Ryobi 18 volt in 1.5 AH, 2 AH, and 4 AH. All lithium-ion and no problems. Huge leap from the old Ni-Cads. I'd go for the biggest if it is cost-effective (sometimes it is not). Ryobi 4000 millimphour batteries are a regular price of $100 each and that is steep. Home Depot is now having a sale on a pair of the for $69. WAY better.

I guess much depends if you want longer use-time, or a lighter weight.

I bought a new one off eBay for my Hitachi, it doesn't have the stamina of the original, but it was only $20!

Bigger is better. The higher the number, the longer it will run on a charge.

The only draw back could be the weight. The higher capacity batteries are a little heavier, possibly a consideration if doing prolonged or over head work.

The only experience I've had with drill batteries is with Dewalt. The replacement batteries didn't near measure up with the originals. Then someone gave me an unused Dewalt drill they let sit until the batteries went bad. I checked into new batteries and when out and bought a new drill. The batteries cost more than the drills are worth.

With the new Lit-Ion batteries, buy replacements makes sense, the old Ni-Cad not so much. Batteries cost more than a new drill.

The government wants to mess with our lives...... why don't they do something constructive and make all tool makers use the same battery! Wait!!!! that would make sense!

Bill, the man that invents a series of adapters that allow you to use any make of battery in any tool is going to be a gazillionaire! :lol:

How would that be different then forcing tractor makers to all use the same engines and transmissions? Or all cars the same parts? No thanks. I like having choices, including with screw-guns.

My first battery-gun was a 1/4" Black & Decker around 1969. Battery was built in and it took all night to recharge it. I am very glad the government did not force everyone then to do the same.

We're talking power source. All cars use the same power source--gasoline, and nearly all tractors use the same power source--diesel. Why can't cordless electric tools all use the same battery, just like flashlights, radios, etc?

Many of the batteries are interchangeable between brands.
Some you have to break off a divider tab at the battery contacts or tool contacts.
google for the subject of "power tool interchange" etc.

you might want to check and see if you have a Batteries and Bulbs store near you. the one I use rebuilds the battery packs.

bobfeather · Dec 5, 2017

Its funny that I have had my DEwalt with original batteries for thirteen years. Not a contractor, so I use it around the homestead.The batteries still kick a$$, The drill kicks out sparks and smoke when I use it. The batts will outlast the drill.

Hello sde,

As stated already more power is always better. Here is how you can calculate it.
Volts x Amps = watts. 746 watts = 1 H. P.
Voltage of your pack times the amp hours is the power or the capacity of the pack. I do make up packs as a hobby,

Hello wfw,

They are the same size sub c on ALL BRANDS OF DRILLS! No drill maker that I know of makes their own batteties, that is a common erroneous assumption! Even the NiMh are sub c size for the same Tool application

BarnyardEngineering · Dec 6, 2017

Yup, the BATTERIES are the same. On the NiCd and NiMH packs they are all "Sub C" size. On the LiIon packs they are all "18650 Panasonic" size.

jeffcat · Dec 6, 2017

I was going to suggest the same as you did. If they are having a slow day they will rebuild the battery pack as you wait. Most of the guys are very nice. The batteries today totally kick butt compaired to when you bought that tool.

Hello BarneyardEngeneering,

Now that is writing will there be no more: I had trouble, low life, our of some
drill brand batteries? Just watch and see!

wilson ind · Dec 6, 2017

cOULD I SEND 6 OR 8 HARBOR FREIGHT BATTERIES FOR YOU { sorry cat pushed caps} to rebuild? Willing to pay fair price set by you.

guido · Dec 6, 2017

Hello Wilson Ind,

I am blade you ask, it means you know I can do the work. It is though too late now, as my garage is not heated. I would do it otherwise. Those are low amp batteries and charge slow, but do the job. If you don't get new batteries for Christmas I will do them for you when it warms up.....no charge. I have never SOLD my rebuilt packs, always given them away. Out of all of that many packs I should be able to get at least two to four packs. If you want you can shoot me an e-mail..... Guido.

Hello barnyardengineering,

True on the "Sub C" False on the 18650's

I was about to toss my Ryobi tools because the Ni-Cads were dying and not holding a charge... then discovered the lithium-ion batteries (on sale two large ones for a little over $100 at the time) and that made a world of difference. I really rarely have to charge the 4 ah ones, unless I'm using the circular saw. They can sit for weeks and still show a full charge, the Ni-cads seemed to die just sitting, even when not in the tool. Get the lithium-ion ones and you won't be sorry. Happy again with my Ryobi tools.
