I rotate a pair of these in my wireless mouse. It is an earlier model that eats up batteries much faster than the new generation ones. I used to have to swap them out every 4-7 Days but these last for 3-4 weeks with heavy use. It's also true that they hold their charge when not in use. I've seen it first hand. I will not be buying any other Ni-MH than Hybrio. I came here looking to buy a bunch of them on the cheap and am shocked to see the price here. They are $TEN at Fry's every day! $Fifteen here at time of writing this. :(

Having a few sets of Eneloops, I bought some of these to see how they compared since they are rated at 2100mAh. There were some reviews saying they top the Eneloop. In a nutshell, these came out exactly the same mAh range as the Sanyo Eneloop.

In two 4-packs, they ranged between 2080 and 2160mAh after putting them through a few cycles to condition the batteries. That's exactly the same range as the Sanyo Eneloop 2000mAh batteries wound up. I was expecting these to top the Eneloop by around 100mAh or maybe even a little more, but that wasn't the case.

These do have a 'cool factor' with the label. Much better than the bland white label.

Since I can find the Eneloops for about eight bucks, I'll use those. These Hybrio's don't have any advantages.

They are both great batteries, so whatever you find less expensive, snag them. They last a good, long while.

5.0 out of 5 stars Finally a rechargeable that works like an Alkaline, June 10, 2008

These batteries do exactly as they advertise. I have a pair of Hybrios in an old digital camera that I don't use often (only take a few shots a week with it). It has been a YEAR since I've put them in and I've yet to recharge them.

I've used normal NiMH rechargeables for years, and they'd always lose so much charge after just a few weeks of non-use that they could not even power up my camera (cameras require a lot more base charge in order to operate than simple electronics such as flashlights, which will use a battery til it's dry). These Hybrios, however, are still powering up my camera after a whole year, and still have yet to need a recharge. (of course they'd run out if I used the camera more often, but that'd be due to use, and not self-discharge from sitting around unused).

I'm not sure how they work, but I know that these and other "low self-discharge" NiMH rechargeables are structurally different than a normal NiMH, which is the key to their long shelf life; i.e., its amazing shelf life is not just due to the quality of materials used, but rather how it's constructed.

Definitely a great rechargeable. I'm never buying a regular NiMH again.
