I took a chance and it is working like a new mirror again. It was a bit tricky to get the silly little plastic button back in place but with a little patience, I managed it. Just put some tape over the button before you remove the grub screws and it should come away with the base that holds the battery. Take a close look at the position of the plastic and if it drops off you will know which way it goes back in, as it's curved on one side. Hopefully it will last another 7 years, then I will be back for another battery. ### ⭐⭐⭐⭐⭐ Easy fix for failing Simple Human light *by A***R on 3 May 2025* Replacement battery for Simple Human sensor light. Relatively easy to replace (lots of videos available) at a fraction of the cost. Very happy with it. ### ⭐⭐⭐⭐ Caution if replacing battery in Simple Human mirror *by W***M on 30 September 2023* 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. ## Frequently Bought Together - AOLIKES 3.7v 7800mAh Rechargeable Battery Pack for Simplehuman Sensor Makeup Mirror ST3026 BT1080 Battery Replacement ST3027 3028 and More, 1s3p Batteries Pack - Ginsco 580 pcs 2:1 Heat Shrink Tubing Kit 6 Colors 11 Sizes Assorted Sleeving Tube Wrap Cable Wire Kit for DIY - WMYCONGCONG 100 PCS 0. 5A 50V DC 3 Pin On/Off 2 Position Panel Mount Slide Switch Micro Miniature Slide Switch --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/87537125-3-7v-7800mah-rechargeable-battery-for-simplehuman-sensor-makeup-mirror](https://www.desertcart.co.za/products/87537125-3-7v-7800mah-rechargeable-battery-for-simplehuman-sensor-makeup-mirror) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-04-22*
