2 Pack 1.2V Sub C SubC 1800mAh NiCd Ni-Cd Rechargeable Battery for Power Tools Battery Pack (w/Tabs)

Great price and easy to install, battery life last pretty Long compared to the Wahl OEM battery, used this battery to replace the dead battery in my Wahl 5 star shaver

Great battery cells to fix my old craftsman 9.6v battery packs. Very good price and very strong performance.

These make me laugh. I'm laughing as I write this. Years ago I bought a Manscraft 14.4 cordless drill. Of the two battery packs that were included, one was sick and the other most dead. I finally thew away the dead one (wouldn't accept a charge). A few years later I found a pack at Saers on the closeout table for $5 (what a stroke of luck). Turns out, that was a much better pack. After years of not needing the cordless drill much, though I used my corded one a few times when using the cordless would have been more convenient, I looked into a replacement pack. The only pack that would still take a charge only accepted a weak charge that would spin the drill at low rpm, and made all the bits I tried seem dull. That's when I learned that a battery pack can be rebuilt and that it was, reportedly, not that difficult. So after checking battery sizes to try to make sure they'd fit inside my battery packs, I finally decided on these "HyperPS 12 pcs 1.2V Sub C SubC 1800mAh NiCd Ni-Cd Rechargeable Battery for Power Tools Battery Pack (w/ Tabs)" from Amazon. And, though the OLD batteries I was replacing were 1300mAh, I took a chance. With my soldering tool (cheap) and a lot of patience, I succeeded. These batteries are, seemingly, fully charged. I've used the drill several times with the rebuilt pack. After every other use or so I recharge the pack but I don't notice any difference. My conclusion is that the original batteries included with the Manscraft drill were a piece of work. And yes, I'm using the same charger that came with the drill. I bought another dozen to rebuild the other pack (Home Derpet will accept your old batteries for recycling) but so far it doesn't look like I'll need the second pack.

Was able to rebuild my old 7.2V drill battery. Works great. Solderd tabs together which are welded to batteries. Two of the batteries had tabs improperly welded that fell off, but I rewelded them.

Great for getting a discontinued battery pack back in the game again, requires soldering and skill to get all the cells to be the same assembled size and leads facing the right direction, I found it to be kinda hard, buy , have someone else do it or grunt it out, I guess it comes down to how bad you want your tool back

I bought these batteries to replace the 1500 mAh NiCd ones in a Swiffer Vacuum. The Swiffer is great for the kids to get up light amounts of dirt and dog fuzz from the floors on a daily basis. Not as good as a big vac but the perfect size for kids, rechargeable (learning to plug something in to make it useful the next day is a life skill), and they can see the dirt they picked up on the bottom of the wipe pad. The batteries were the right size (length and width) and had VERY convenient tabs that were easy to solder together. The tabs were also replacements for the standard male side wire connectors that the original battery pack had to attach the power. The 20% increase in power may prove detrimental to the aluminum/ plastic vac motor but it may make it stronger (*** Sorry, this previous sentence is wrong because I always associated amps with power. ***) I have not had any problems in the 3 days of use so far. The photo is of the battery pack that was replaced. The batteries look exactly as the they do in the product photos. Update on the batteries : It's Feb 2017 now and the Swiffer is going in the trash. It was not getting used much because the batteries do not hold a charge as well as the original ones did. I had fun with the repair but it was not worth it in the long run. I still think the Swiffer vac is a good idea but needs more power and to be able to hold the charge longer. I hope this info was helpful.

I bought a batch of these NiCd's to rebuild a Craftsman 19 v. C3 drill battery. 11 of the old cells tested OK (1550-1650 mAh) with an automatic charge/discharge device, so I just replaced the 5 bad ones (not ideal, but should work if capacity matches) with these very reasonably priced Chinese batts with tabs, nominally 1800 mAh. Testing each, after 3 conditioning cycles, and before doing the rebuild, showed they were close to this, and well matched, 1740-1880 mAh. My only criticism: the tab material is very thin, so I doubled over the adjoining tabs as much as possible when soldering together. The rebuild went fine, using all the other original parts, fuse, thermistor, etc. Charging in Craftsman charger was normal, with no overheating. I've not drilled with the batt yet, but a slow discharge test shows normal capacity, and I will store the pack at ~50% charge, or less, to avoid crystalization. Doing this, supposedly, and in my experience does, keep NiCd cells viable for many years, whereas storing on a (non-smart) charger (as many do, and I did before studying NiCds in depth), where they stay at full charge and warm all the time, can cause failure in less than a year! Only time will tell if these HyperPS cells, treated optimally, will perform in the long haul.

I rebuilt a 7.2 battery pack for an Ace hardware sander which was no longer available. Works very well now!

I bought these to rebuild two Black and Decker better packs. I had to remove the negative terminal tabs for my application, but they come off easily with pliers. They all came fully charged and after the rebuild, the tool works as good as new.

Very pleased with my purchase. Arrived day earlier than promised, well packaged and product as stated in description. Had many problems soldering tabs, until I used an abrasive tool to surface, then followed with acid flux and using lead bearing solder wire. Follow with a baking soda mix with water to neutralize/ This worked well for my out of manufacture battery pak

Just got them but so far the two I am using in a rechargeable soldering iron work fine, and that's a challenge as the soldering iron draws about 20A when it quick heats. It's also worth noting that the tabs are very long and come insulated with heat-shrink sleeve, which is a plus.

Knowing that with rechargeable batteries, you typically get what you pay for - ie lower priced batteries have high capacity claims - so I ordered these batteries in the hopes I was wrong. When I received them in a loose generic plastic bag with pairs of batteries shrink wrapped together, I thought that I might have gotten exactly what I paid for - ie cheap low performance batteries that probably won't work. After opening the packages, I placed the batteries in my SkyRC MC3000 charger and had the charger go through 3 discharge/charge cycles and recording the capacity of the batteries during each charge cycle. To my surprise, the batteries came about 1/2 full so they were capable of holding a charge. To my further surprise, each battery tested HIGHER than the rated 1,800 mAh - it ranged from about 1,850 to 2,050 mAh with an average of 1,950 mAh! Those are pretty good numbers for the batteries in this price range. I would have liked to see a bit more consistency so that the batteries are better matched for a battery pack but given the price point, that might be too much to ask. Overall, a good buy for a rebuilding dead battery pack or replacing NiCDs in your cordless vacs.

One of the soldering tabs on a battery fell out. It doesn’t look like it was welded. The rest seemed robust. Unfortunately, we cannot finish the project as we need 20 batteries.
