HQRP 3.7V Li-Ion Battery Compatible with Philips Sonicare HX6150 HX6902 HX6910 HX6911 HX6912 HX6932 HX6933 HX6952 HX6982 HX6311, FlexCare Platinum HX9170 HX9170/10 HX9110 HX8911 Toothbrush 49x14mm

So my Sonicare HX9120 battery died, no longer holds a charge. Bought this one to replace it. Battery itself fits great (dimensions) and the pins are actually mounted securely but the pins are not offset unfortunately. Thankfully I am soldering handy and I was able to remove the pins from the dead battery and reuse then on the new one. This took a bit of difficulty since the news pins are mounted on so well. (Not sure why other reviews said they snapped off easily. These oins were VERY secure and connected with 4 solder points to the battery.)So be forewarned of the above if you have offset pins.Otherwise, great battery and it's sitting on my Sonicare base right now. Will update in a few months with how it's holding up!

It worked with my Philips Sonicare FlexCare toothbrush. Be careful with the terminals, they brake really easy. I had to brake them and solder the terminal plates of the original battery to the terminals, so at that point I pretty much used this battery as a replacement AA battery. This is helpful since you don't have to do any soldering with the next replacement, you just have to remove the connectors of the next one and place it in the battery pocket.

After a couple of years or so, the original battery in my Philips 7000 series shaver stopped taking a charge. While it's a chore to dismantle it to get at the battery and then desolder/remove its contacts, it's worthwhile considering the cost of a new shaver. The new battery functions well.

Initially this seemed like a great buy - it worked well for about 4 or 5 weeks, but then it stopped holding a charge. The brush works again, but won't hold enough charge to finish a brushing session.

Fantastic capacity. I used this to replace the battery in a 2007 Norelco electric razor. After 17 years daily use the capacity of the original battery had dropped to just 2-3 days worth. I bought another Norelco, but then thought, 'hmmmm', and bought this battery. I have not used the new razor more than a week and have continues to use my trusted razor with this battery.After a charge it has now lasted 45 days without another recharge and is still as eager as ever. I am beyond impressed.If this fits your application go for it. In my experience, this battery delivers.

If you have a solder sucker removing the old battery is much easier. I used mine to get the old battery out of a Sonicare HX6930. The install for the new battery went fine and it started right up when I turned it on. Only time will tell if the longevity is there but so far so good.

University of YouTube showed me how to replace the battery in my older Norelco shaver. This battery was an exact replacement. Desoldering/soldering skills are a requirement so if you aren't comfortable with tearing something apart, scrambling it up then putting it all back together and make it work you may want to reconsider. Really it's not that difficult, way less than a new shaver!

It’s ok.
