As we publish guides on how to repair electric toothbrushes we are often asked – when buying a new electric toothbrush, which models will be easiest to repair or replace the battery in when the battery eventually stops holding a full charge? Below is our current answer to this question, as of this year.
Total Cost of Ownership
As well as the one-off initial cost of buying your electric toothbrush, there is the ongoing cost of replacing the head every 3 months. We would go for an Oral-B (Braun) rather than a Philips Sonicare toothbrush due to the fact that genuine replacement toothbrush heads are available more cheaply and this is the main ongoing cost with electric toothbrushes. The brush heads are usually on special offer in at least one of the big UK supermarkets at any given time, and are often half price in Superdrug too. The only exception to this are the Oral-B iO toothbrushes which take special heads that can cost £15 each!
Once the internal rechargeable battery of your toothbrush is worn out and only holds enough charge for 1-2 days use it can be replaced by following one of our battery replacement guides.
Too Much Choice
There is far too much choice when it comes to picking a new electric toothbrush. Each manufacturer has many versions and colours of the same handle and/or internals which they package up with different combinations of heads and/or accessories and then sell as a different ‘model’. Oral-B do this the most. Hopefully below we can pick out the main choices for you.

There are many currently available Braun Oral-B models. Type numbers are generally not visible on packaging apart from misleading ones and the labelling system can be confusing so go by the name printed on the box.
- Vitality models: These are the cheapest and most basic models and they do not have the third “dimension” of tooth cleaning i.e. vibrating the head back and forth in the direction the bristles point. It is straightforward to replace the battery with easy soldering once you get the handle open, which can be slightly more difficult with the latest handle design. Although this is Oral-B’s cheapest model the long-term savings are negligible.
- The PRO 2 and PRO 3, also labelled as Pro 2000 and Pro 3000: These are Oral-B’s mid-range models. They have one button on the handle to power on and switch between fast and slow speeds. The pressure sensor light is useful for both new and experienced users. They are the most compact toothbrush but the battery can still be replaced. Needs fine soldering. Available new on eBay here.
- Triumph v2 models labelled as ‘SmartSeries’ 6000, 6500, and 7000: These have two buttons on the handle. Easiest brushes to desolder the battery on. Extra brushing modes and bells & whistles if required. Sometimes labelled as a 5000 (with 2 buttons) but not to be confused with the 1 button version labelled as a 4000 or 5000 which is different. Still available new from eBay here and from Amazon here.
- Genius and Smart 6: Expensive, with lots of modes and features that might be unnecessary. The battery can be replaced once it is depleted. Needs fine soldering.
- iO series: Most expensive, with lots of modes, features and app connectivity. The special replacement heads are very expensive compared to standard Oral-B heads and Philips Sonicare heads. However, the battery can be replaced without soldering or special tools.

Don’t forget that if you don’t have a 2-pin shaver socket in your bathroom to plug the charger into you will also need to buy a shaver adaptor plug, which plugs into a standard 3-pin UK/Ireland mains wall socket and has a fused 2-pin socket on the back of it to plug your charger into. Beware of unfused ones which are dangerous and do not meet UK/Ireland electrical safety standards.
