The best rechargeable batteries--period! [Posted on 2007-12-12]
These really are the best rechargeable batteries available for general use. Just like Rayovac says, they combine the best features of alkaline and NiMH cells.
Low-drain applications:
They don't last quite as long as alkaline, but they last for plenty long enough that the inconvenience of having to change/recharge them sooner is more than offset by the convenience and cost savings of being able to recharge them. For example, I use 6 AAA Hybrids as backup batteries in two baby monitor transmitters. Through testing I have determined that I should recharge them just every six months. If I were using alkaline batteries, I would need to replace them once a year. If I were using non-hybrid NiHM batteries, I would need to charge them monthly.
High drain applications:
They last just as long as regular NiHM batteries of the same mAh rating. OTOH, my Hybrids are 2100mAh, but some of my non-hybrids are as high as 2800mAh. But even here, the convenience of being able to charge the dead hybrids as soon as you've replaced them, and then store them charged for months before using them is a great time saver over having to charge regular NiMH immediately before use. To me this is well worth the somewhat lower mAh ratings.
Cons
You're not supposed to charge the ones I have in 15-minute chargers. It works, but I've read that this may reduce the battery life from about 1000 recharge cycles to 100 recharge cycles. It also seems that they don't charge as fully in a 15-minute charger as they do in an 8-hour charger.
Conclusion
For overall versatility and ease of use, these are by far the best rechargeable batteries you can get. I can no longer justify using alkaline batteries, and find it hard to justify using regular NiMH batteries as well.
Hybrid batteries ROCK! [Posted on 2007-12-17]
I'm a believer in this new generation of batteries. I was using long-life Lithium AA in my BT mouse and everyday camera. That cost me about $10/month to replace. For the same cost, I got a set of AA Hybrids. (about $16 for 8 AA) That's a one-time cost, so break-even $$ after one month, now "free". They hold their charge as claimed, you can use your old NiMH charger, and have about 75% as much juice as Lithiums. I swap to freshly-charged batteries every couple weeks, and I'm always ready. No more wondering how much juice left in the expensive Lithiums. Hybrids...yea!!!!
Great Battery [Posted on 2008-04-06]
I will never buy another regular nimh battery again. I have been using a set of Rayovac HYBRID in my Canon 580 ex Speedlight flash for a year now, and been so impressed with them that I have replaced every other rechargeable battery in my house with these. I knew they were good, but it wasn't until recently that I found out how good. I was asked to photograph a friends wedding. Inside, after sunset. I needed full flash. I got over 150 flashes, many as fast as I could push the shutter to get the candid shot, before I started to get even a moments delay on recharging the flash. All in all, I ran 200+ flashes in an hour and a half, and still had plenty of charge left for more, although the delay was starting to become noticeable. I have no idea how this compares to a set of lithium batteries, as I have never used anything but rechargeable in this flash unit, but I know it's 2 - 3 time more then I ever got out of a set of standard rechargeable. I've even started intentionally leaving the AA charger, and spare flash batteries, at home, even when I plan on taking night shots during multi day photo trips.
Cheapest Price among the Popular Brands of Low Discharge Batteries [Posted on 2008-06-20]
(This review was for the Rayovac - seller replaced the original product reviewed with a different unnamed hybrid brand)
The new one from Rayovac is rated 2100 mAh.
These are the new breed of Nickel Metal Hydride batteries. Now you can use them for your TV remotes, wall clocks, etc. where you need longer shelf lives. One of the reasons why NiMh batteries have become so popular was the proliferation of digital cameras. But for those casual shooters who sometimes leave there batteries in the cameras and 3 months after pick it up for another special occasion; they often found it as a surprise that their batteries are depleted. With these new batteries, the charge will almost as good as the last time you used them.
Pros:
-Low discharge. Ordinary NiMh batteries discharges even just sitting on the shelf.
- Works with your existing NiMh battery chargers.
-Conventional size and dimension. I had other batteries that I have to use a screwdriver to remove from my camera because it is fatter than other "AA's".
-Cheaper price compared to Eneloops and Duracell
Cons:
- More expensive than ordinary NiMh
- Eneloops and Duracell last a bit longer
My 6-month Rayovac Hybrid honeymoon is over... [Posted on 2008-08-18]
I bought 2 sets of these batteries for my Canon PowerShot A630 back in January 2008, and everything was fine until a few weeks ago (late July 2008), when I was unpleasantly surprised to see my camera's "low battery" warning light coming on much sooner than usual for these particular batteries. Given that I've been using two sets of these batteries interchangeably (I marked them so that I could tell them apart), I'd estimate that each set has only been recharged around a dozen times. I've been using my Energizer "slow" charger all along, and I've noticed lately that the batteries seem to be getting quite warm -- I'm assuming that's a sign of trouble... Go figure... After a terrible experience with Energizer non-hybrid 2500mAH batteries last year, I'm beginning to lose hope in rechargeables...
