Braun 6520 won't hold charge even with new batteries

If your shaver works but will not longer hold a charge as long as it should, the batteries need to be replaced. If the shaver is dead and the green indicator no longer illuminates when plugged in, you have waited too long and the circuit board is now damaged and can not be repaired.

Model 6520: If the green light no longer illuminates when you plug it in, you have waited too long to address the battery problem and the circuit board is now damaged. Replacing the batteries alone will not help as it will still not be able to recharge. To repair, you will need a new circuit board but Braun has discontinued for this model. You will be lucky to find one at this date.

model 5520, 5525, 5550, 6520, 6525 and 6550 are all prone to this problem when you neglect batteries that no longer charge correctly. It is suggested that batteries be changed early on when you notice that they are a problem instead of running your shaver from the cord until it dies.

Here is an equivalent circuit diagram good enough to repair the circuit board - What I have found is that the batteries go bad, draw too much current and blow the fuse or in the case of mine, over current the transistors. Resistors are in ohms

Assuming that your cord is not damaged, the circuit board is bad. This most often happens when you continue to use the shaver well after the batteries have lost their ability to hold a charge well.

there may not be anything wrong with the batteries and circuit board at all. you may have a bad motor

The cost to repair this isn't going to be nearly as much as a new Braun shaver as nice as this one.

The problem is that your rechargeable batteries have become degraded to the point that they won't take and hold a charge. Because the batteries have become so degraded, that even with the power cord plugged into an outlet, you still can't use the razor solely on AC power either.

If you want to have the shaver repaired for you, you can contact www.electricshaver.com or give them a call at 1-888-476-1785 to get an estimate of the repair costs. Typically it takes about a week or less once they receive your shaver. They also stock most parts for many brands of shavers, including your Braun. I've used them for getting parts for several of my shavers and found them to be a very good company.

If you're handy and have a soldering iron you can disassemble the shaver and remove (unsolder) the bad batteries and solder in a new set. There are two small caps on the bottom of the razor that cover the screws that hold the body havlves together. Remove these with a small pick or small flat bladed screwdriver and remove the screws and carefully remove the body halves and that will let you get to the main board and the batteries.

Simply heat up your soldering iron and melt the end tabs off the batteries and remove them. Then solder in the new ones and make sure they are properly secured and have adequate solder on the tabs for a good connection. Put the covers back on and install the screws and and the caps and your all set for recharging the shaver. Let it charge for at least 8 hours and you should be all set!

So whether you decide to have the repair done for you, or do it yourself, I hope you find this Very Helpful and best regards!
