3.0 out of 5 stars Low cost, but VERY low capacity, December 20, 2009

This review is from: Rayovac Rechargeable NiMH Batteries, AA-size, 8-count Carded Pack (Health and Beauty)

The latest family of Rayovac rechargeable NiMH batteries are all missing one thing: the capacity rating. Previously, you can see the charge capacity (such as '2500mAh') marked on every package and also on each cell. But newer Rayovac rechargeable NiMH cells are just grouped into three classes ('Everyday-Use', 'High-Energy' and 'Hybrid'), with vague claims such as 'Up to 275 photos' printed on their packages.

Of course, those claims make very little sense to us, because Rayovac never tell us which camera was used, and under what test conditions were those photos taken.

After a lot of searching, I was able to find the spec sheet for those cells from rayovacindustrial dot com:

- NM715-4OP 'Everyday-Use' AA, 'Up to 275 photos': capacity=1400mAh
- NM715-4B 'High-Energy' AA, 'Up to 375 photos': capacity=1900mAh
- LD715-4A 'Hybrid' AA, 'Up to 400 photos': capacity=2100mAh

The item offered here is the NM715-8OP (the 'OP' stands for 'Opening Product'). It has the LOWEST capacity amoung all Rayovac NiMH batteries. I have tested some in my La Crosse BC-900 Battery Charger, and the average capacity is actually higher than spec at 1500mAh. But this number is still very low by today's standard for NiMH AA cells. So although the price looks attractive, this is just not a good value.

As of this writing, this 8-pack (NM715-8OP) is actually priced higher than two 4-pack (NM715-4OP). Furthermore, the Rayovac 4.0 AA 4-PACK is available at even lower cost. Those are low-self-discharge cells with higher capacity of 2100mAh. So it is a no-brainer which package you should buy.

[Update on July 16, 2010]
I recently discovered a hidden benefit of those Rayovac 'Opening Product' AA cells: they are exactly the same size as alkaline AA cells, while other NiMH cells with capacity 2000mAh or over are all slightly thicker. So for some appliances with extremely tight battery compartment (such as the Rayovac Sportsman Xtreme 1W LED Flashlight), those are the only rechargeable cells I can use.

[Update Sep 4, 2010]
As if the offerings above is not confusing enough, Rayovac has now discontinued the 'Hybrid' series, and replaced it with another two types:

- LD715-4OP 'Pre-Charged': capacity=1400mAh
- PL715-4 'Platinum Pre-Charged': capacity=2100mAh

5.0 out of 5 stars Don't judge a book by its cover, January 4, 2010

This review is from: Rayovac Rechargeable NiMH Batteries, AA-size, 8-count Carded Pack (Health and Beauty)

I bought these from Walmart. They were priced about half of Energizer! I couldn't see the capacity rating (mAhr) anywhere on the package, nor the batteries, so I was very skeptical. Finally, I couldn't stand the price and gave it a try for a pack of 4. After a few months, I went back and buy another pack of 8, and from now on I'll only buy Rayovac.

Here's what I found. Although not hybrid, these batteries keep their charges much longer than any normal NiMH batteries I have tried e.g. Energizer, Sony, and other no brand names. I put these on a train toy for 3+ months. The Energizer was almost dead but Rayovac was still half full (my Sony charger can detect that). After a fresh charge, they also perform much better for a demanding device. I had a (bad) digital camera that needs 1.5V batteries and most 1.2V NiMH couldn't even turn the camera on. The Rayovac CAN actually drive the camera for a while, impressive.

Anyway, since Rayovac does not make the capacity claim so it could mean that the quality could vary from one package to another. So far, I am happy. The price is worth the risk. For normal NiMH batteries, if you left them drained and forget to re-charge for a few months, the batteries would never perform the same way again. A lot of my NiMH died that way. Having batteries that keep their charges longer will also ensure that their life time is longer.

I purchased many a AA Rayovac from Amazon. Just about everything in my house that requires a AA battery has these. Highly recommended and last a long time--both charged and longevity.
