Your tests are greatly appreciated.

I have a question about capacity. Is there a general rule that tells me how deeply an eneloop is discharged based on voltage. For example 1.35V is 50%???

Thanks

Thanks for all your reviews. You are a reference to me. :slight_smile:
I suspect that you are doing this in your job too? What do you do exactly? (just curious)

No, some years ago I did develop electronic, but now I mostly do software. I do maintain a full electronic lab at home with a lot of equipment.

Oh ok.
I’m a you graduate. I have a Master in µelectronics and I’m currently trying to get some equipment at home, but my budget is tight.
I really like your reviews. You should think about posting some pictures of your home lab equipments!

Yes, equipment can be expensive. Some people buy second hand equipment, old HP and Keithley stuff is often perfectly fine.

Check some of the links at the bottom of the review, there are pictures.
