How to interpret this parameters about Eneloop AA

[Jamisonlm3]

What would be the minimum and maximum voltage?* 1.2 and 1.5. What would happen if i’m over or under these values.

I wouldn’t worry about it. Usually, NiMH are charged to 1.45v. If the voltage is under, it just means the battery isn’t fully charged.

I see 1900mAh, but sometimes when it’s charging i see is over 2000mAh, is that normal?

I also wouldn’t worry about this. As long as it’s not going a ways beyond 2000mAh. Besides, don’t rely on charging mAh to tell you how much capacity a battery has. A discharge test is better for that.

What would be a normal value for the mR (Resistance)?* I see these values change a lot and are not always the same. For example yesterday i get 52mR for 3 batteries and 49mR the last one.

I’d completly ignore the IR reading on any charger. These are known for being inaccurate and unreliable. There are better ways to measure it.

What would be the best current for a discharge test.* Now i’m discharging 3 batteries at 500mA. I read somewhere something like 15C or 3C but i don’t understand what it means.

I usually do a discharge test of either 500mA or 1A. I wouldn’t worry about anything higher.

And last one. What would happen if i forget to remove the batteries from the charger?

I think most chargers will trickle charge the batteries. I’m not sure what this one will do. I might charge them until they are ful and then just stop only to start to charge them again when they’ve self dicharge enough. Either way, it shouldn’t hurt them as long as you don’t leave them on too long. Eneloops are great batteries. Once charged, just take them off and store them. Leaving them on the charger over night shouldn’t hurt them.
