Question about Health & Beauty
How do you open the shaver to access the batteries? I have removed the metal clip.
Just de-solder the red and black wires and pull out the battery. Put it in a plastic bag to stop it shorting out on anything metal or cover the terminals with tape. The battery must be recycled properly as it contains toxic cadmium. As long as the battery is not leaking then it poses no threat to you. Refitting the new battery is just as simple, re-solder the red wire to the +terminal and black to the -terminal. Be sure to charge the razor as you would a new one i.e. 8 hours. Hope this helps.

I have the .PDF file from remington for disassembling your shaver for you. Also this model is known for poor battery life and I recommend replacing the NiCd batteries with Lithium Ion batteries of the same size. This will give you much more shave time and 10 time the number of recharge cycles. Post me an E-mail address where you want me to sent the instructions to you or you can just E-mail me and request the instructions and I will attach the .PDF to my reply letter ( firstname.lastname@example.org). If you enclose your number I will call you for free and walk you through the process.
I hope you find this information valuable. If you do please take the time to rate this a FixYa. If you ever need my help again post it here and I will be notified of your need for further assistance by E-mail. I do this for a hobby so there will never be a charge.

• Thoroughly clean the razor cutter area
• Pull off (straight out) cutters and lay aside
• Release spring clips and remove
• Gently pry up and remove rubber boot
• Pry case open starting at cutter end and bending up toward connector end
• Thoroughly clean razor interior area (blow out)
• Pull up motor and remove black oscillator bars
• Pry up the circuit board by releasing the cutter-end catch using a small tool to push it in while prying gently up on the cutter-end of the board and bending up
• Clean the board and turn it over
• Note battery polarity and mark on board if not present already
• Unsolder the battery tabs using unsolder braid. Be careful not to short the electrical circuitry as the batteries are electrically LIVE at this point.
• Remove the old batteries and fully clean off the circuit board solder-pads using unsolder braid.
• Mark the installation date on the new batteries in a place where it will be visible
• Install new batteries, making sure the polarity is correct (cut the tabs to a correct length if they extend too far through the circuit board)
• Solder the battery tabs being careful not to short the electrical circuitry as the batteries are electrically LIVE at this point
• Re-install the circuit board and other parts following the procedure in the reverse order (be sure to put a soft rubber pad over the motor to hold it firmly in place when the upper case half is snapped in place)
• Before installing the metal retaining clips be sure that the rubber boot is fully free and not pinched between the case halves
• Finalize the assembly by reinstalling the cutters and screen

This shaver was pretty clearly not designed for battery replacement. To open, first remove the screen and blades, and unhook the metal collar from the tab on the back of the case. Then carefully pry off the black inset on the front of the shaver. Underneath it, near the bottom are two screws. Remove these. The case is now only held together by several plastic latches, which can be carefully pried apart with a small screwdriver. The two 2/3A size batteries are soldered to the printed circuit board, which can be pulled out (don't break the wires to the motor) by a little wiggling. The original batteries in mine are 1100mAh, and I have just ordered 1600mAh replacements. The new ones don't have tabs - so soldering them in place is probably going to be a challenge.

In the PDF instructions it describes how to remove the batteries. The instructions fail to mention that there is a spit of yellow glue that is holding one of the batteries to the curcuit board with a death grip. Undoubtedly, you will have to use a knife, not in the glue, but on the skin of the battery. Pull on the teather wire, and slice the battery skin around the glue.
If after removing the batteries, and you are not thouroughly discusted with the manufacturer, then purchase a couple of AA Ni-cad batteries solder the positive of one battery to the negative of the other. then solder the free positive end to the red wire, and then the blue wire to the free negative end. Then try to remember how to reverse the process and put it back together, without leaving any parts out. ;-)
There is a risk of injury by overheating the battery when soldering. That should be avoidable if you remember how to drop solder. Just like its name, it involves having the wire securely held in place. Then hold solder iron over the wire/battery end. Then take some rosin-core solder and apply the solder to the hot tip. Then make sure the newly melted solder lands on the contact. Keep in place until it cools and holds the wire to the battery.
If you think this is better than writing to Remington complaining that they did not make it easier and use contacts, instead of solder, so we can simply pop in a new set of batteries. Or maybe look at other manufacturers, and see if they are any better.
