New internal battery in the handle.

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.

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

recharge / replace the battery

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.

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.
