Review: Works in my CPAP sanitizer - Used to replace the battery on a CPAP hose sanitizer. Could not get the battery replaced by the cpap manufacturer nor at an electronics store. This battery is the exact same size. Just required some spot soldering of wires to circuit board. Easy peasy. Now the sanitizer works like new plus I have a spare battery when the current one dies. Saved a lot of $ by DIY.
Review: Perfect! - I purchased this anticipating that the connector would be incorrect and I'd have to splice on the original. Well I'm happy to say that was not necessary, although you will still need to check polarity and correct if needed. The connector for perfectly and the battery has great capacity. One thing I'm really happy about is the fact that it includes two other connectors with leads and heat shrink so this battery will fit 3 different applications if you're not exactly sure which tiny white connector is the correct one. I love it when folks think ahead. Definitely worth the money!

### ⭐⭐⭐⭐⭐ Works for Simple Human soap dispenser

Used this to replace a battery in a Simple Human soap dispenser. Had to change the connector, but I knew that would probably be the case. Powering it just fine. Will update if it dies within a year.
