When I put my Braun series 7 in the cleaning station everything is good. It pumps liquid up to clean then it starts to pulse and the vibration shuts the system down. I redo it with the same result.

I wonder if you can charge the shaver with the cord. Or is the battery dead?
Please also check if the blades of the shaving head are pressed on correct. It is the cleaning system, what pumps up the fluid, and after a while is the the shaver that should start pulsing. So it must be an error with the shaver. If the shaver works normal but does not when not in the cleaning station, also check the contacts on the shaver and on the cleaning station.

R9370 won't work

Any corrosion on the rechargeable batteries usually means that they've gone bad.
For an relatively easy to fix test, disconnect one end of one of the cells wherever it's easiest to solder back together. Then plug in the shaver and see if it works. The LCD may not work, but the shaver itself might.
Looking it up further, I see that it uses a 12VDC cord/charger. So if you try my suggestion, the LCD and shaver should work when plugged in, if the batteries are the problem.

Razor heats up when i charge it and it won't turn on

Most likely, the batteries are bad. If the charging light still illuminates when plugged in, you should be able to change the batteries to fix the problem.

Norelco 4805 xl razor won't turn on when plugged in nor will the battery charge. i would think it was the battery but it does't want to turn on when plugged in either. is the motor shot? thanks

When the battery goes completely bad, the shaver will not work even from the cord.
You will need to open the shaver and make sure that the batteries have not corroded badly and damaged the inside of the shaver.

You will find the correct replacement battery offered at See link below

You will also find a video tutorial on this page to halp show you how to open the shaver. See link below for another video with additional installation tips

My toshiko trimmer is not getting charged, even after charging for 6 hrs it works hardly for 5 seconds and stops.what should i do?

mcdevito75 here, Sounds like the batteries won"t take a charge anymore. Refer to the Toshiko website at for battery replacement, however at times the batteries cannot be replaced as they are attached to a circuit board and, you"d need to replace the shaver.
