    How many batteries does the shaver take?

  • Jim Gish Oct 31, 2010

    It takes one battery -- it's a AA size with a special button on each end which snap into the battery holder in the shaver.

It is far simpler than I thought to replace the battery. First, you cannot find the replacement from Panasonic (other than somewhere in the UK and for about $15). Ideally, get a AA NiCd battery with solder tabs. The quick way to do this is to get a portable phone battery and take it apart. You will then have two replacement batteries! Don't tear off the tabs on the batteries, just cut the batteries apart (I got a pack with 2 batteries). Fold the tabs back over themselves. Remove the three screws holding the ER203 together, pop off the back, pop out the old battery, push in the new one with the grooved end of the battery toward the clipper end of the shaver and with the battery tab fold down. Instead of the posts on the original battery, you will be using the tabs to make contact at each end. I had to push a bit to get the battery into the slot as the old battery is a bit shorter than the standard NiCd even with tabs. Reassemble (watch out for the adjustment knob). Plug in and let charge. Clip!

Your Trimmer uses Ni-cd battery, which provides 40 minutes of shave time with one full charge of 8 hours. It seems that either your battery is dead or the cutting element is clouged. I'd suggest that you wash the cutting elements with warm soupy water and then try to turn it on again.

If that doesn't work, your battery is probably dead. If the unit is within warranty, you can contact Panasonic support for a replacement or else try replacing batteries with the help of a local technician or a repair center.

Hope this helps..

The battery on my Panasonic ER203 shaver is reaching its end of life. I found the battery number on this site. I was wondering how many batteries does this shaver take? (I have not opened it yet; I didn't...

If you open the set you can find a battery pack which is mae for the panasonic shaver. But for replacement you can put along the available ones inthe market by looking at the voltage and amperage. The curent (amp) factor is most important as this is what drives the motor for the time period.
There are also many models of the AAA or AA that can be suited to fit the space to give this VA rating.

Poblem with my panasonic lumix dmc-fx7

It may that your battery has lost its charge, or has leaked? If it won't hold a charge try taking it out wiping it and trying again if that doesn't work you may need a new battery.
