Do you think Rayovac batteries work as well as Duracell/Energizer?

I haven't done any testing lately.

Just an FYI, never use "Heavy Duty" batteries in high drain devices. Heavy Duty doesn't mean they have more capacity, it means they are designed to last longer under low drain conditions, even though they also lose more of their capacity over time in storage.

I'm too lazy to look up specs for Duracell and Energizer batteries, but Rayovac AA cells have ~2500mAh with a 28mA load and ~1650mAh with a 650mA load.

Edit: Okay, I lied.

Energizers regular AA's contain 2800mAh with a 25mA load and 1400mAh with a 500mA load. Interesting.

There is a difference in testing methodology though. Rayovac specs the discharge to 0.9V and Energizer to 0.8V.

Duracells contain 2800mAh @ 50mA and almost 2000mAh at 500mA loads, also to 0.8V.

It's hard to directly compare, though, because for example... the 50mA test is 4hrs a day, and the 500mA test is 30 minutes a day. Energizer's specifications is continuous discharge.

Rechargeables FTW


Rayovac has their new hybrid rechargeable batteries. Supposed to hold their charge longer in low drain/no use.

The blue Rayovac Maximums are great for the price. They last probably 90% as long or more as the Duracell/Energizer. I don't know if Rayovac still makes the red and gold ones, but those suck

Rayovac > Duracell/Energizer.

IMO Rayovacs die slightly sooner than Duracell/Energizer, but not enough to warrant the price that they charge.

Get a decent set of rechargeables, and a charger. You'll save money in the long run, especially for RC stuff. Spend the cash up front and get 2 or three sets for what you need.

While a little harder to learn how to use, a decent hobby charger can really help out. You can charge in a little more than an hour safely, and shorter times if you don't mind shortening the life of the battery.

Something like this:

Will work in your home, or off a 12V (car) battery. It will do a better job than any charger you will find in a consumer (wal-mart) type store.

PM me if you're interested in more info on how to go that route.

I've been using Walgreen's branded batteries for a couple years now, and they seem to last as long as Duracell, for about half the price.
