Cannot get the back off of my shaver to replace the battery...

To change batteries, remove three screws on back. The third screw is hard to see. To access it, you will need to remove the trimmer from the point that it pivots out from the shaver. Use a small flat screwdriver to gently pry the small plastic pegs from their corresponding sockets on the shaver body. Remove back cover. Inside, remove the metal clip that covers the batteries near the bottom of the shaver. Unsolder the batteries from the wires. Solder in the new batteries.

To change, remove two screws on back and remove back cover. Remove plastic clip that is in the way of removing batteries. For easier replacement, it is suggested that you use a modified installation technique. This is to break the tabs off of the old batteries rather than unsoldering them from the circuit board. This allows the old batteries to be removed but leaves the tabs attached to the circuit board. You can then solder the tabs from the new batteries to the old existing tabs

hi minglim, welocme to the forum!

Replacing a Norelco Shaver Battery Things You'll Need:Torx screwdriver set Rechargeable Ni-Cd AA battery 1)Slide up the sideburns trimmer on the shaver .2)Try the various torx head screwdriver sizes to find the fit for the two screws holding the top of the back shaver cover on. Unscrew the two screws that are under the sideburns trimmer that hold the back of the shaver on. On some Norelco shavers, the back will now slide off if you apply downward pressure on the shaver's back. Other Norelco shavers have one or two torx screws on the base of the back cover on the shaver; if so, unscrew them also. Place the screws in a safe place. 3)Take the back cover off the shaver. Some shavers may have a strap fastening the battery down. Unfasten the strap if there is one. Take out the battery. 4)Replace the old battery with a new rechargeable Ni-Cd AA battery. Re-fasten the battery holding strap if there was one. 5)Replace the back shaver cover and re-screw in all the torx screws,

The rechargeable batteries are solder into the circuit board of the electric shaver. You'll have to use a soldering iron to de-solder the terminals/tabs from the PCB (printed circuit board) in order to get them out.

Then you'll need new replacement rechargeable batteries to solder back into the shaver.

You can get teh correct replacement batteries from Electric Shaver Service in Lincoln, Nebraska (if you're in the US or Canada). They even do service and repair work in about a week, if you want to have them fix your shaver for you.

Here's a link to the battery page with your shaver model's rechargeable batteries for about $15.00 (plus s&h)
