Replaced the factory battery in my nearly 10 year old Norelco 6885XL that just wouldn't hold a charge anymore. It was a great shaver and I hated to replace it, so I figured I'd try to repair it. With this battery pack and a set of replacement heads, it's like a brand new shaver!Yes, there is some shaver disassembly and desoldering/soldering involved. In my 6885XL, there were some small plastic retaining pieces that you have to carefully remove and replace. As far as the soldering, it wasn't a big deal for me as I solder regularly, but for those inexperienced or less equipped for soldering (a desolder pump or wick is a must to do the job easily), I see how it might be awkward or challenging. If your shaver is like mine, you need to desolder and unbend the tab ends from the *bottom* of the circuit board, then just pull the tabs completely out with the old battery. Replace with the new battery and insert tabs (check polarity!) into holes, bend them over, and solder again on the back of the circuit board.

Works as expected. Although unfortunately the shavers are made to solder in the batteries, I was able not to have to solder them in. I was able to leave a tab of metal in the shaver from the old batteries by breaking the old tab off close to the old batteries and bending the left over metal into a spring like tab with which the new batteries labs can be bent to have contact with. I've done this with two Norelco shavers with good results.

My husband's Norelco electric shaver wouldn't hold a charge. Because he had just purchased new heads for it we thought about sending it to a repair center until I came across this battery at Amazon. My husband was able to easily install the battery since he owns a soldering tool. The shaver works like new and we saved money! Thanks Amazon!

Ok

I replaced the original battery with this product a few months ago.The original battery had worked for more than 10 years. But this battery started to have problems after a couple of charges. Now it's totally dead (after 5-6 charges).Never buy this product.Either the one I bought is a defect or it's a fake.The quality of this product is totally unacceptable.

The battery fit into the shaver very easily. A problem that you might have is making the connections from the shaver to the battery. Just leave the prongs sticking up and lay the new battery down onto the old prongs. Be careful that you get the battery to lay down good into the shaver because I had to take the shaver apart the second time because the on/off switch would not work. I did not have the battery down good into the shaver.

I have no issue with the battery; I would have liked to have known before hand that the installation was a bit tricky. Do not expect a quick fix; you don't just change out these batteries like any old AA or AAA. You have to remove the old ones and solder in the new ones. So if you don't own a soldering iron and don't feel inspired to learn a new skill, I would suggest buying a new shaver all together.

You need to be good with a soldering iron to install this, but I put it in almost 3 weeks ago, charged it up, and it’s still running strong on that initial charge.
