New internal battery in the handle.

recharge / replace the battery

cannot see why not , after all it sits on the shelf in the shop for months until it is sold

Every battery dies the same way, regardless if it regular or rechargeable battery. However, on a rechargeable battery, it will die after certain numbers of recharged. No rechargeable batteries last a lifetime, it will burn out and have no recharging capability. Replace the battery if allowed which I doubt if it's a sealed unit. If their screws allowing you to take it apart to replace the battery then you might have a chance, but good luck finding an exact replacement battery.

Your electrical socket may be wrongly wired, with polarity mixed up. Try another socket. Also, some electric toothbrushes need to be "off" to successfully charge. Maybe the flasing red light for 10 seconds is telling you the toothbrush is "on" and not accepting charge.

Check whether your brush is still in warranty. Either way take it to an oral-B certified shop for fixing as there's no point paying to have it fixed by someone who doesn't really know what they are doing.Good luck

I had the same problem at the beginning of the year. I think i had bought 3 electric tooth brushes and all seemed to cave in within a couple of weeks. My friend recommended going to Macy's to buy one, which I did and it is still going strong. Maybe you charged it for a very long period of time and it overheat the system circuit? I'm not sure but I would recommend getting a new toothbrush.

Hello!

The lamp may be lit when charging but is not actually charging the battery.
It is better to check first the terminals to where the battery is inserted inside the toothbrush. Corrosion build up in the terminals may lead to improper contact with the battery.

You can remove the corrosion by dipping a cotton swab in a lemon juice or vinegar and rubbing it to affected area. The acid will help dissolve it. You can also try rubbing it with any metal to expose its contact surface.

I have bought many rechargeable devices and about 4-5% of them have bad Chinese batteries in them. I also have converted nearly all battery operated items to rechargeables and these often have spotty performance with several out of a couple of dozen not worth keeping. You might try running the batteries down as far as possible and then trying to recharge. If they are NiCads, they may have developed 'memory,' a known weakness of that type and NiMh batteries in particular seem to need several charge/discharge cycles before they will come somewhat up to their rated capacities.

Hi, you are healthy and you have nothing to worry with your uterus based on oral B check.
