Brymen BM 235 Startup issues
<< < (4/8) > >>
wraper:
Also if meter struggles at 1.3V per battery, it means that more than half of Alkaline capacity will go to waste.
GLouie:
I'm using white Eneloops in my Dave-branded BM235 and am not having any problems, even after some months.

I use Eneloops whenever possible due to repeated leakage problems with all alkalines.
bc888:

Same as Glouis. I use the BM235 meter infrequently as I have a Tek 850 that stays on the desk ready to grab, same set of eneloops(white) for a couple months in the bm235, meter still working as of 2 days back. Which doesn't tell anyone what the batteries are currently measuring of course and therin lies the question.
Specmaster:
Rechargeable batteries when new are completely different kettle of fish to rechargeable batteries that are not so new clearly as the OP has already reported, the meter is performing perfectly on alkaline batteries.

I have tried to use rechargeable batteries myself on a many occasions and it has been my experience that once they are a few months old, they do not seem to be as effective as they were and then at that stage alkaline just seem to be a better bet all round and in general more cost effective as the rechargeables are that much more expensive to begin with.

I have tried many makes and capacities and the end result is the same, a few charging cycles and the performance drops off, maybe I've unlucky and have brought batteries that had been shelf sitting too long I don't know.

Regular NiMH have extremely high self discharge rate. After a half a hear they will be empty on their own, without any load. Eneloop does not have this issue. Also unless you do something ridiculous to them, they'll last hundreds of recharge cycles without any noticeable degradation. BTW just buy white IKEA LADDA, they are Eneloop pro in disguise for a fraction of the price.

Also they don't leak. Alkalines leaking twice in my Keysight U1272A and back cover replacement was enough to decide never buying them again.

That's some first class nonsense BTW. They easily last for more than a decade if treated properly.
