I have not been impressed by the Tronic brand. I also purchased the green pre-powered batteries that they occasionally do to and they proved to be servicible but not a patch on Eneloop batteries. I purchased loads of them though as they were half price and ideal for clocks and such like.
I have 4 AA 2300mAh Tronic “ready charged” and they are fine, probably not as long lasting as Eneloop Pro, but less than half the price. It’d be interesting to see some cycle testing.
I got some AA and AAAs but beware they are BIG! They will not go near a minimaglite. They seem OK though. Voltage was a bit low one week after a full charge, but for the price (£2.50 here) can’t be beat. Cheaper than duraleaks.
Ok… After a charge/test cycle on my C3100, I am getting:
2250, 2270, 2283 and 2284.
All pretty close, and not a kick in the back side away from the claimed capacity. The lowest (300mAh) Came back to 2070. I’ll give them a week and run another discharge.
The C cells are all showing 3800/3900ish after one charge/test cycle.
They won’t be getting heavy use or very many cycles in this house, so at roughly half the price of alkalines, it’s a no brainer for me, even if they only did 100 cycles!
