Works great.

Looks good

I ordered in April '23 and received the Kastar Rechargeable Shaver Battery Pack AA 2.4V 2000mAh for my Norelco 4845XL electric razor. I know, I know, it is an old razor, but it still works just fine and all it needed another set of rechargeable batteries to continue its life a little longer. Of course, you have to unsolder the old batteries from the printed circuit board, then resolder these new batteries in, but if you have a pencil type soldering iron and a little solder, it isn't difficult at all. The batteries already come with tabs that fit thru the circuit board for soldering (make sure the tabs are clean and bright [steel wool] before trying to solder)! Taking the razor apart (finding all the hidden screws), soldering, and reassembling was accomplished in less than 30 minutes at home. Now, once these were installed the red light on my razor stayed on almost constantly, normally meaning the batteries needed charging! I charged these new batteries fully until the green light came on, but after a short use time, the red light returned. I charged the batteries several times, but I finally just ran the razor until it wouldn't run any longer (discharging fully both batteries) then charged the batteries fully, and the charged/charge needed lights now work correctly. The batteries come with a charge on them which, apparently, fools the circuitry once installed. Now, the lights (green and red) function correctly and the battery powers my razor for a couple of weeks before needing to be recharged! I am pleased with the batteries and the power they provide to this razor! I'll just have to wait to see how long the life of these batteries are!

Arrived quickly and charged up. I used these before and they last longer than the white batteries did.

These batteries are working well in my Remington shaver. I ordered an amp-hour battery that was significantly higher than the batteries in it. I did not know what batteries were in my shaver until I opened it up. At that point I found the new batteries were significantly bigger than those in it. That meant I had to modify the battery compartment to make the new batteries work. After modification everything went well. The moral of the story open your shaver first determine the size battery you need before ordering. Then order the size you need.

The water pik cordless version is real handy when I am travelling, but it was not holding a charge anymore. It was a little tricky to open the unit and get at the batteries inside, but basically required a little bit of manipulation after opening the screws. To replace the batteries, you do need to be handy with a soldering iron to remove the existing batteries and connect in the new ones; these batteries come with tabs (but not pigtails) so you cannot connect them by just twisting wires together. Other than that, it was pretty straightforward.

work, but not a full charge

Perfect match for my old Norelco razor. Not an easy installation if you don’t completely suck out the old solder where the battery tabs go through the circuit board as the tabs are very thin/ bend easy. Fun to do the repair anyways. Make sure you have a solder sucking tool!!!

good replacement

All good

Purchased this item to replace defective cells in shaver. Item easy to fit, as it has a link at one end and solder tags for the positive and negative terminals. Charged up and running well.

Old shaver like new. needs soldering

Comme commander et avec Amazon et intercom, toujours satisfait du délai.👍
