I'm probably the last one to switch over to these, but since I have several
cams including a DSLR that take these, I decided I'd better get some better
batteries. I like the fact they hold their charge far better than the standard
NiMH fare.

yes, they have torque. On my camera, they may start to show half battery... but if I stop shooting for a minute or two, the indicator goes back to full battery. I've occasionally managed to run a set down, but that with great effort. Laughing

The nicest thing is that they hold their charge when unused, unlike the regular rechargeables.

Yes, positively recommended. They keep their charge for a year, behave very consistent across one batch, and are slow at losing capacity.

While they are not quite up to industry grade NiCd and high-current NiMH cells as far as current is concerned, that is rarely a concern - few devices taking AA or AAA cells were ever designed to make use of special high-current cells, most stuff expects old consumer NiCd, NiMh or Alkalines, which were/are all below the Eneloop specs.

The best rechargable there are!

Duracell and Rayovac make hybrid batts that are spec'd the same as
eneloops, come precharged. Walmart sell the Duracell for $12.97 for 4.
I just bought a MAHA smart charger that analyzes and conditions/charges
8 batteries at a time off ebay.

The Sony "Cycle Energy" batt's are the same as the Eneloops. Just rebranded.

Right, Bill.
I think the key for keeping the batteries running for long time is the charger. Cheap chargers that recharge the batteries in batches (2 or 4) do not take into account the differences among them. It's not adequate to try to charge two batteries with different charge load at the same time inside the same circuit. Having a charger that charges them individually for sure will extend the life of them.
And is mandatory to have a switch-off-at-the-end-of-charge function. The cheap ones that remain charging the battery until you remove it are real battery killers...

I've been using GP batteries and GP Powerbank chargers for a long time and they have given me a very good service. But they do not store the charge for more than a couple of weeks, so maybe is time to move to Eneloop as well.

Thanks for sharing!-

Jes.

Yes. A slow-smart charger is very conducive to battery life longevity. Don't go with the "fast" chargers.

In my experience, intelligent pulse chargers are best, but to be intelligent, they have to be at least somewhat accelerated - ΔV detection (the only safe way of determining charge status in a NiCd or NiMH) does not work reliably if the charger is not charging at one fourth of the capacity per hour or more. Given the recent increase in cell capacities, old turbo chargers or a recent semi-fast charger would fit the bill - but old slow intelligent chargers cannot detect the status of current cells any more, as 100-200mA is below detection limits on modern cells with more than 1800mAh.
