Average Reviews:
(More customer reviews)Talk about a confusion campaign! Currently, you can find not one, not two, but FOUR different series of low-self-discharge ('Pre-Charged') rechargeable cells from Rayovac:
- The original 'Rayovac Hybrid' (LD715),
- The 'Rayovac 4.0' (RF715-4C) with ambiguously titled 'Lithium Technology',
- The Rayovac LSD NiMH OPP AA (LD715-8OP), and
- The newest 'Rayovac Platinum' LSD Series (PL715-4).
The 'OPP' (Opening Price Product) series offered here is typically priced lower than others. But its rated capacity is very low at just 1400mAh. By the way, you'll not find this capacity number printed on the battery or on its package, not even from the official Rayovac consumer web site. I have to go to 'Rayovac Industrial dot com' to dig up this information.
The packaging is another example of deceptive advertisement. It says: "Takes up to 8x MORE DIGITAL PHOTOS!" in bold red letters. But then the fine prints says: "vs. Energizer Ultimate Lithium when recharged 25 time". So if you do the math, it is actually saying that those NiMH cells can only take 1/3 the number of photos per charge, when compared to Ultimate Lithium.
I have tested four of those 'OP' AA cells, using my old La Crosse BC-900 charger/analyzer. The measured average capacity is slightly higher at around 1500mAh. But note that all other Rayovac LSD series are rated (and measured) at 2100mAh.
The self-discharge rate of those 'OP' AA cells is quite good. After three months sitting on the shelf, the average remaining charge is about 87%. This is in line with the self-discharge rate of Rayovac Hybrid and Sanyo Eneloop.
[Bottom line]
You may pay slightly less for those 'OP' LSD cells, but the capacity you get is also 1/3 less. Worse yet, this capacity number is not marked on each cell. So if you ever mix it together with other LSD cells, it will drag down the capacity of the whole set. Avoid this product if possible. Consider other low-cost alternatives such as the GP Recyko Pre-Charged AA instead.
[Aside]
I can only think of one application where the lower capacity of 'OP' cell is an advantage. You can pair this 1.25V NiMH cell with a 1.65V NiZn cell, to get almost exactly 3.0V out of two rechargeable cells. It is important to select two cells with the same charge capacity (1500mAh), to make sure they run down at the same rate. The down-side is that you need two different chargers to recharge your batteries.
