-- NiMH - Energizer vs. Rayovac (http://discussion.visorcentral.com/vcforum/showthread.php?threadid=14512)

I was just at my local Target looking for rechargable batteries for my Platinum. I found that Energizer and Rayovac both had NiMH and they were exactly the same price. Does anyone have experience with either of these and have a preference. It looks like the Energizer are a little more powerful according to the specs on the package. Which should I get? Thanks - Jim

Ray-o-Vac

I use Ray-O-Vac because their charger allows you to recharge all of their batteries. NiCad, NiMH and rechargeable alkalines. Since I use all three kinds for different purposes it is convenient. I use AAA NiMH's in my digital audio player and rechargeable alkaline AA's in my cameras for warm weather and NiCad's for cold weather. I also use rechargeable alkaline AA's and AAA's in all my all too numerous remotes. If the energizers have a higher mah rating then they should give you a longer run time per charge, but it may or may not be significantly different. I have a Prism so I do not use separate batteries. Hope this helps.

I use both and rotate them. I don't know which lasts longer but I install runtime and let you know.

I don't use either, I use Radio Shack's Nimhs. I've been using the same two pair for quite a while. I usually have to trade them out about once a week.

I use GE/Sanyo NiMHs. They have a capacity of 700mAhrs. Most other NiMH AAA batteries have 550 to 650mAhr capacities. I also have some non-branded 650mAhr and 600mAhr NiMH batteries. The shorter battery life of the 600s versus the 700s is very noticable.

Rayovac just sent me a whole load of coupons, so you can guess who I'm going with..

Now.. how did I get on that mailing list?!?

Still think the Radio Shack $15 wall charger is the most solid charger I've run into...

bookrats - where did you come across this info? I'm not doubting you, I just am curious since I recently bought a Maxell charger, and have charged the Energizers with it. The Energizers are rated 700 maH, and the Maxells are rated 550 maH I think.

Now, for people who really understand how batteries work: does that make sense?

The Energizer charger I just saw could charge not only AA/AAA but also 9V batteries. The Rayovac charger next to it couldn't. Of course I personally haven't seen a 9V device in years, but maybe it's a consideration for some folks.

The Radio Shack charger is very primative. It is using a simple timer to end the charge cycle. It does not seem to be doing any automatic sensing of when the battery has been fully charged. Hence the two timer settings.

I have a Maha MH-C204F NiMH/NiCd battery charger. It it an intellegent fast charger and will automatically terminate the charge cycle when the battery is fully charged. It does this by monitoring the battery voltage as it charges. When the battery voltage stops rising and then drops a bit, the battery is full and the charger reverts to a low current trickle/top-off charge. No need for a high/low capacity setting.
