Are my Eneloops genuine?

Cool, it looks like they're genuine then. I got them from this seller on eBay.

Those are a little cheaper than the ones I buy at Thomas dist. so I think I'll try them out next.

Not bad a price indeed.....very good in fact. So how do you like them man...have you used it yet.

I haven't really had a chance to do runtime tests, which is what most interests me. ;) I'm currently charging the cheap BTY NiMHs that came with my charger to make sure the charger won't destroy my Eneloops. The charger cost $7.00 including 4 AAs and 4 AAAs. It's not exactly a high-quality device. It's supposedly a low amperage charger, which is what I wanted. And it does appear to have four individual channels. The only problem is that when I put in more than two batteries the individual red lights above the batteries don't light up, just the green one in the center. The green one in the center seems to run all the time, so I doubt it will indicate when the charging cycle is done. I guess I'll just leave them in for 24 hours. It does appear to be charging them, because I gave it 20 minutes and tried one of the batteries which I had previously drained dead, and it had charge in it. So we'll see.

As I remember it is a 200mA charger which is neatly on 0.1C (a tenth of the rated capacity). The standard for charging at 0.1C is for 16 hours. They are probably safe in the charger for a day or two but it is a bad idea in general to leave cells on charge indefinitely. Nor is it necessary with low self-discharge cells to top them off before use. It is best to run them well down (Around 0.9-1V per cell) then charge them back up. If your power is flaky or prone to brownouts, a little longer won't hurt. If you can, it is a good idea to keep an eye on the power supply voltage - the cheapest of multimeters will usually do this- just remember not to electrocute yourself.

Overcharging kills more rechargeables than anything else.

Thanks Don, I was planning on topping off the Eneloops, I don't think I will now. I guess I'll just commence with a runtime test then!

I normally fully discharge all my nimh batteries with the c9000 before doing a regular charge, r/a or break-in. I keep records on all my cells so with a full discharge, I get pretty accurate mAh totals.
