The other night the weather experts were calling for Snow-pocalypse in our area, and to be prepared I began re-charging many 18650s that I had discharged to under 3.9v to store.
After I was done with that, I started topping off the many Eneloops I had in 2 larger lights. I only had 2 decent chargers and 14 batteries to charge, but then I found a Duracell charger that my mom must've given to me. So I tossed 4 Eneloops onto it. Later, the Xtar charger had finished charging its batteries, so I removed the 4 AA from the Duracell charger, which were still charging, and put them into the new Xtar charger. I was surprised to read that they were being measured at 1.51v on the Xtar, and I assumed it was wrong.
I removed all 4 and tested them on my DMM that I had been using throughout the recharge process, but it also read 1.51v on all 4 batteries. After about 20mins or so, they dropped to 1.46v, which made me feel better.
I've charged many Eneloops on my old I4 charger, but they usually come off of it at approx 1.44v as I recall. Another issue is that the Duracell charger appeared to still be charging them when I removed them at 1.51v. Now, maybe it was just seconds away from terminating their charge cycle, but who knows(?). Is it a problem?
