3.7v 7800mAh Rechargeable Battery for Simplehuman Sensor Makeup Mirror ST3026 / ST3027 / ST3028 / ST3029/ BT1080 Battery Replacement 1s3p 18650 Batteries Pack

We have the original Simplhuman vanity mirror which is now 6 years old. Could not buy a battery from the supplier and was told to replace the whole unit which was a waste. Found this and fitted perfectly. Would highly recommend

I’ve had my mirror for a few years now and the charge was not keeping up as it did. The new battery has made a huge difference and is as it was when new. Great outcome.

Saved throwing a £200 simple human mirror away when the battery died, really easy to fit and working perfectly

Cable its too short to allow cover to be refitted!

My Simple Human mirror wasn’t holding any charge at all. Almost certainly the old battery was at the end of its life. Having taken the back off, changing the battery looked easy, so I ordered this battery. Somewhere I got the tip that you must put a bit of tape over the outside of the switch, prior to taking the back off, which I did. However, this didn’t stop the tiny piece of metal falling out of the switch from the inside. I could hardly see it and was trying to relocate it, when it pinged into the back of the mirror, never to be seen again. Nothing worked after that. Simple Human don’t do repairs, but they did offer me 20% off and you can get another 10% for signing up to marketing, so you might consider just buying a new one.To add insult to injury, whilst I’m not usually an idiot, I was convinced the polarity was reversed and so rearranged the wires, but then realised I was wrong, so I can’t even return the totally unused battery! A disastrous project for me.

As a battery pack it works (although I have not tested the rated capacity). As others have mentioned, despite having the correct connector for a Simplehuman sensor mirror, the lead is too short. I had to extend it using the lead from the old battery with a soldering iron and some heatshrink sleeving. However, I haven't found anywhere else that sells this pack with this connector so you probably would always have to do this.

Installed this in my SimpleHuman sensor mirror. The wire was long enough to fit into the circuit board though it took a little bit of finesse. But it fixed the dying original battery and lasts much longer now.
