Question about Norelco T770 Beard Trimmer
Since there is no other option than to use the rechargable battery I cannot use the trimmer. This trimmer has not had much use and is only a couple years old. Is there a repair service that can fix it without cost to me?
I did everything possible to find help as I did not accept the answer from Norelco. They told me that there is no way to change the battery except by a qualified repair shop. I made them admit that they basically made a consumable device so they can get you to buy new shavers in the future - in so many words.
I finally pried the thing open as carefully as I could. Once opened, you will find 2 batteries glued together. They are Ni-Cd 2,4 volt - 600 mAh batteries. Looking all over, the only store that helped me was Battery Plus. There are stores all over the country storeloc.aspx">http://www.batteriesplus.com/t-storeloc.aspx .
They sold me two 1.2v 1000mAh batteries for $3.50 each. For another $5 they spot welded them together with tabs for soldering the 2 wires on.
Okay, after getting the new batteries, I went back to my old batteries and slowly pried the tabs of the top. They pretty much snap off as they are only slightly tap welded on.
I then took out my model soldering gun and with a little patience, soldered the two wires on to the new leads on the new batteries.
Within minutes, I had the thing put back together and charging. It works great and now I can tell all of those who said it can't be done - or those who wanted $40 to refurbish it, to go scratch - I GOT MY SHAVER BACK!!!!
We all need to learn to stop living in a consumable world. I have a feeling due to the economy we are facing, we will all try to save money in this manner.

A cordless phone battery works perfectly as a replacement on the T770. I used a battery for a Sony BT-T50, Ultralast # UL950. Just need to cut off the plug and solder the wires to the main board.

I followed the advise of hmosoff, only I took the battery and the PC board to Batteriesplus. They had the batteries and did all the work for the cost of the batteries. My trimmer lives again!

I basically followed hmosoff's solution once I got the trimmer open. I ordered a 2.4V 800mAh NiCd battery pack w solder tabs (should look like the trimmer's installed batteries) from an online battery dealer (Interstate Batteries) for $10.48 w S/H. I cut the wires from the trimmer's main board where they attached to the old battery pack's tab. I stripped a little insulation from the ends of the wires and soldered them to the replacement battery pack's tabs. After reassembling the trimmer, it's like new, and I look forward to using it for many more years.

I just spent 10 minutes replacing the batteries with regular AA (not the best environmental solution but feels a heck of a lot better than buying a whole new shaver). With a little tape you can do it, too.

I thought my batteries wouldn't charge so I followed hmosoff's instructions but it turned out to be the switch. Regardless, I bypassed the batteries and the switch with wires to where the charger hooks up and used an adjustable adapter that I have for my camera using the 3 volt setting. Since I don't have a switch, I turn it on and off by plugging in or unplugging the cord at the base of the trimmer. It works great! never had this kind of power using batteries!.
I used a meter to compare the voltage on the batteries that came with the shaver and rechargable batteries from my camera and they are the same so I think almost any AA rechargable batteries would work.
