Easy recharge
Great that you can recharge 2450 batteries, which you would not expect. Rechargeable batteries don't last as long as the non rechargeable ones when in use. I'm having to recharge them every 3-4 weeks, whereas non rechargeable lasted 2-3 months in the same device. Would like to see rechargeable batteries with higher capacity, but overall, still saves cost on buying new batteries all the time.

Not as good as I first thought
UPDATE: Bought on 30th. January 2024 and it's broken, less than 5 months! The micro USB connector has "fallen to bits", and it shorted out the PSU (that. fortunately, survived). Reduced it's stars accordingly. ORIGINAL REVIEW: Lightweight and easy to use. The batteries, LIR2450's, seem to charge fairly quickly - I haven't timed them. More charging slots would be useful, I have five candles that use these batteries and it would be helpful to be able to charge at least four batteries at a time. Otherwise, it does a good job.

Battery isn't 3.7v
Even though the batteries are rated as 3.7v, the batteries I got were around 4.0-4.2v. Please check the device before you buy those as it may not be compatible with your device.

Might have just had a dodgy device
I've of the button charging cells working intermittently. Easy return but disappointing. Could easily have been a one off though.

Rare product
It’s rare to find a button battery charger. Giving it a test.
