Lithium Coin Button Battery Charger for 2450 2032 2025 2016 1632 1620 Rechargeable Lithium-ion Button Batteries

I used this to charge two depleted batteries from my Oticon MiniRITE S hearing aids, and it worked perfectly. The process was quick and efficient—you don’t need to leave them charging for hours. Once the batteries reach the proper voltage, the hearing aids’ charger takes over seamlessly. Highly recommend for anyone needing a reliable solution for depleted hearing aid batteries!

Charges different sizes of coin batteries with no problem. I've changed several different sizes of batteries that will take a charge but a few of the batteries wouldn't take a charge so you don't waste your time trying to change them.

Husband has Oticon miniRite more 1 hearing aids. They are rechargeable. Both his current ones, and previous set he keeps as backups. Well, his current right hearing aid stopped working so had to send it in for repair. went get out the backup (also rechargeable), but it had been so long it was dead. And I mean so dead that the Oticon charger wouldn't recognize it. Got the dreaded 3 flashing red light.These have a "tamper resistant" case. But thank heaven for Reddit saving the day!Redditors recommended this button battery charger from Amazon so I did and it got delivered overnight. After getting the case open (pretty tricky) I was able to get the battery out and insert it in the charger, which was also very tricky because it turns out it is not for these super small 384/392 batteries. Anyways, after some finegaling, it charged them fully in a couple hours! Now the regular Oticon charging station can keep them up! Yay Reddit and Amazon!

A very good, compact charger for the larger button cell batteries used in many rechargeable systems and some watches. It can charge from 1-4 batteries at a time. ONLY comes with a USB connector, so you need to have a separate transformer to use line outlets for charging. You probably have a few for your phone or Pad, but why can't they just include one?

I was excited to get this charger for my collection of worn-out coin button batteries. I use many different types of coin batteries in home automation system.First of all, some batteries might look like being charged by the indicator on the charger showing red light, but some of them not. I believe it depends on the worn-out battery status whether it's too much discharged beyond any possibility being recharged. Some batteries look like being charged, but it never changes the status to a fully charged status regardless how long it's on the charger.When the battery looked like fully charged by the changing indicator light (red to blue), it doesn't hold charge at all. As soon as it is inserted into the electronics, it becomes dead battery again immediately.I should have known that these coin batteries are supposed to be one-time use and cannot be recharged. I was naively hoping that it could.In summary, forget about recharging the dead coin batteries. This CT-ENERGY charger doesn't work, in that matter any coin battery charger that claims to charge dead coin battery.

Most button batteries are lithium RECHARGEABLE IT PAYS FOR ITSELF ON 3 batteries! Will not be disappointed!

My trikes have FOBO tire monitors and the batteries were not lasting long at all. Now I can recharge them with a backup ready to go. The rechargeable batteries seem to last a lot longer.

works as it should...so far
