Looks good

Just what I needed, It fit perfectly. so far it holds a charge and works

I have a Norelco 7825 shaver for the past 25+ years. Not bad considering I only have to shave every other day. If you are reading this, you either have a shaver that the batter is not holding much of a charge or you want to know how to fix the one you have. Youtube has plenty of videos on how to do this replacement even though the video may not be of the exact shaver, the process is pretty much the same. For me, this was my findings. Taking apart the shaver is very easy. Two screws, remove the cover/side burn trimmer, a couple of metal supports, and there you have the circuit board and batteries exposed. Once you life the circuit board, you will see where the DC motor wires connect towards the front of the circuit board and the battery leads just behind those connections. When desoldering the battery connection be careful not to get some flux onto the surface between the battery + connection and the motor solder point. If you, like a few reviewers here, the shaver will continue to run even if you press the power button. Why? Because you have just basically directly connected the battery to to motor. It happened to me so i know. I just scraped off the excess flux/solder the bridged the connection and it was fine. On my shaver, the leads off the new batteries were too short. So I ended up cutting the leads off the old battery with a dremel. This left some leads sticking up to solder the old/new ones together. Same charger seemed to work fine, although NiMH charging requirements are slightly different than that if NiCads, for its intent and purposes, should be no real world problems. Recommended to purchase this if you are comfortable with basic soldering and hand tools. No need to replace the shaver if all else considered is working fine.

Easy to replace the old batteries in my shaver. These worked better than the original. You will need a soldering iron to make permanent connections.

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

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.

Works great.

Charges fast. But it gets REALLY HOT! I’m afraid to leave this unattended because I’m worried that it will catch on fire.

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.👍
