It happens now and again – rarely, but it does – that we service an old type Braun Oral-B Triumph brush, we send it fully charged back to the customer, they are using it for a good while until the new battery runs empty, put it onto their charger and nothing happens. Bugger. We then look at the brush again, put it onto one of our chargers and the brush is charging. Welcome to the temperamental world of Braun chargers.
Particularly this model is known for the fact that it can develop a life of its own. You might have two brushes of this type with one working with your charger and the other one not. Unfortunately there is not an awful lot you or we can do about this. The battery service itself was clearly successful – otherwise we would have informed you about any issues occurring but your newly serviced brush will not take charge from your charger. If you got access the another charger of this type; maybe from a friend or relative, have a go with that one. You might find that your brush is charging with that one and even that their brush is charging with your charger.
The known issue with charger type 3731 is that it can develop a fault which basically reduces the current that flows through the charger into your brush. If you haven’t got another charger at hand you might be lucky to snap another one up on eBay.
