just put some decent batteries in my BC-900

so first off I practiced on some La crosse cells(free with the charger) :thumbsdow
After a refresh they came in at 2480 2450 2170 2510 (supposed to be 2500MaH) before the test they were even worse.


I also got 8 free Sony Eneloops I'm going to try next, but the real bonus so far is the Maha Imedions, they are LSD cells, supposed to be 2100MaH. They came in first at 2190 2200 2180 2190 after a charge and test at 500ma after a discharge and refresh at 500ma they came in at 2350 2290 2260 2310:twothumbs:twothumbs
These look like really nice batteries for my new light(LD10) I was expecting to use the Maha's for my single and double lights, and the eneloops that came with the charger in a TK40 I had on preorder. Unfortunately I got hit with a nasty vet bill and had to cancel the order.

hoping to pick up a large light with good runtime for camping in the summer(4 or 8 AA) maybe the TK40 will have a price drop by then.

I'm very impressed with the charger and batteries, especially considering the price difference for the same # of decent cells and a C-900.
 
Hello Rocketfish,

You values appear to be charging capacities. Actual capacity is measured during a discharge. Most others are reporting discharge capacities in the 2000 - 2050 range, and perhaps just a little more when using the BC-900.

I think Vidpro was just teasing you a bit. THe Lacrosse batteries are pretty famous (or should that be infamous) for being somewhat overrated. As for test Mah- well there really is no perfect way to test the batteries while under a load and most manufactureres give battery ratings based on the theroretical limits of the battery chemistry. BUT that being said I would say you've got a decent batch of "free" batteries. Keeping in mind there overall cost to you and the intendeded usage (I would not put them in a light that may play a part in a life or death situation) use them and enjoy them!

That's strange, I thought the test function was designed to actually give me the readout from a discharge?

Likewise, I thought that running a discharge/refresh cycle would take the same information(MaH tested by discharging the cell?)

Yep, I'm very happy overall, total was well under 1/2 what I'd have paid to get a c9000 and comparable quantity of batteries and holder here.
The Lacrosse batteries will be abused mercilessly. for any sort of job I don't want expensive batteries to get damaged by.
I'm sure I'll think of something for them soon:)

yup i was just bugging you , in a few weeks you will have sperimented more and known more about it. in a few years you will discover what is a good battery and what is not, and somewhere in between there and there everything will change again. :thinking:
