Review: Great replacement for non-rechargeable Lithium button batteries - Used to replace the button battery in the key fob for my BMW i3s. Original battery lasted ~2 years, so far I am over a year (since 3/2022) into the first charge on the first battery and no issues. I keep the spare and the USB charger in the glove box so I have a ready replacement and charger when it needs to be replaced. Not quite as cheap as a bulk pack of the single-use batteries, but a much more environmentally conscious choice as lithium is quite toxic and most people would just throw the single-use ones in the garbage where they would wind up in the soil eventually. Well worth the slightly higher price in my opinion.
Review: I have been using the CT-ENERGY batteries for about months now and I am very happy with them - I bought the CT-ENERGY 2 Pack 3.7V Lir2032H Rechargeable Button Batteries to replace the ones in my key fob.

## Questions & Answers

**Q: does the first two charge at a slower rate than the 2nd two? is that the difference on the 40 and 70mah**
A: Yes, if charge the LIR2032 battery at 70mA 4pcs at the same time. the 40mA is slower than 70mA. But the 40mA can support LIR2032 LIR2025, LIR2016 batteries charging. 70mA only support the LIR2032 70mAh charging.

**Q: Will it charge a 3.6v lir2032?**
A: Yes it should.  The "li" is for lithium an "r" is rechargeable.  A letter after 2032, if it has one like "H" means high capacity of around 70mAH.  Some are 40 mAH and do not have the "H".  This charger is designed for a 3.6 V coin cell which is rechargeable many, many times like the lir2032, whether high capacity or not.  Do not try to charge cells that are not rechargeable like a CR2032.  To my knowledge and lir2032 should be rechargeable.  Hope this helps.

**Q: I put the batteries in to charge and there is no blue or red light. What does that mean?**
A: Mine was defective, as well. Only two of the slots charge. The others don't work. I just live with it. I'm sure if you contacted the seller that he would do right by you. I only need one battery at a time, so I just live with it.
And be careful about using the rechargeable batteries. I use mine for a 2 battery head lamp. The rechargeable batteries that come with this unit are very powerful. I directly replaced two normal batteries with 2 rechargeable. And it fried a head lamp. So
 I had to put foil in one battery compartment and 1 rechargeable battery and it works fine.

**Q: Can i use it for logitech k750 keyboard that uses an ml2032 battery?**
A: If the device uses 2032 batteries then yes. This charger comes with 4 rechargeable 2032 batteries so if the keyboard needs more than 4 batteries you will need to get more rechargeable 2032 batteries.

### ⭐⭐⭐⭐⭐ Logitech K750 ML2032 battery Replacment
*by J***) on May 20, 2024*

Great replacement for the keyboard battery!!! I got 2 to replace the batteries in 2 keyboards at least 8-years old. One battery was at 100% upon installation, the other at 96%. Charged and now 2 working keyboards! NOTE: Do not dispose of lithium batteries in the trash! Luckily my company has a recycling location were we can put depleted batteries for proper disposal.
