Girafus Button Battery Charger for Cr2032 Cr2025 Cr2016 Rechargeable Batteries -> Lir 2032/2016/2025 with 4X Lir2032 3.7v Rechargeable Batteries Included - USB Coin Cell Battery Charger

2 batteries were dead on arrival. Company sent new ones free of charge. Been using for 6 months and haven’t bought any new batteries since. These rechargeable Batteries get hot sometimes when I first started using them. I don’t know why. Not lately thou. Try to charge once a week. I have to say its working great so far. Quite happy with the setup. Maybe in next version a more robust design for 4 at once?

Used it perfect

Great replacement option for the coin cells on most of electric motored garage doors controllers and car keys.As the coin batteries included are rechargeable there is no additional waste.

I’m glad I bought this because I am tired of buying those batteries all the time and spending a fortune. It’s working good so far. I would recommend it to my friend.

good for an old man

Good quality, batteries are all functional, case is very handy.

I am not impressed. I put the charged battery in with 1 hour it is dead. Please tell me why!!!!!!I do not have the box to send it back and don’t know where to send it.

The batteries would only charge for a few minutes and then showed fully charged but they didn’t power my devices. Returned.

I should be writing about the charger, but as the buttons lose their charge so quickly the charger is effectively a white elephant in black plastic. Standard button cells will last at least 10 times longer, which means recharging is too burdensome, even if it does help the planet. I'm afraid the huge number of 1* reviews are correct. It's a waste of money.

Initially I was perplexed that something with around 500 charging cycles could ever just give me around 3 charge cycles but months upon months later the great team behind Girafus helped out, not just with the product itself but tips of maintenance:Apparently it is not a good idea to run these button cell batteries down to the dregs and place them on charge as this is what causes failure. Rather the team advised me to allow a drainage to around 10% then proceed to chargeVery happy with the company and the main device has always remained resilient and functional

The lid is difficult to open and the battery clamps are a bit fiddly to release but that’s the only downside to never having to buy a strip of button cells again. The charger is obviously tiny but seems well made and the batteries take an hour to recharge. The real upside though is never being left with a dead remote control (Nvidia Shield)

Bought this as a back up to the one that comes with the Girafus cat tracker, so i could charge a battery whilst one is in the tracker, I am very disappointed as 4 out of the 8 rechargeable batteries didnt last long, and now wont recharge in either of the charging units. Hope the futher 4 do not fail as I will have to use non rechargeable and this will make the cat trackers very expensive as the batteries dont last long.

I didn't even know things like this existed until my Logitech K750 Solar Keyboard failed. It's a tidy little unit, a little bigger than I expected but still OK.The USB charging socket is a godsend, it makes it easy to use wherever I'm trying to use it. Well done for that.The only minor niggles are that it's hard to remove the batteries, I end up using a screwdriver to pull the spring back, and the lights are a little unclear inasmuch that sometimes mine were flashing red and green. I'm sure if I read the manual it'd make sense, but you shouldn't have to read a manual for a battery charger. The lights are plenty bright enough.
