How do you like the Powerizer batteries from BatterySpace?

How would the Powerizer 2000mAh compare to the Energizer 2100mAh?

Will they recharge in 60 minutes with a Rayovac 60-min charger?

I have a fair bit of rechargeable battery knowledge from my RC car stuff and the charge rates the 15 & 30 minute chargers are using on AAs people don't even use on the Sub-C packs that RC stuff runs on. Heat is the enemy of NiMH batteries and the faster you charge and discharge them the warmer they get, You can't even hold the batteries for any length of time after they come out of the 1 hour charger because they're too hot. :eek:

Wow. My "overnight" charger gets warm, but definitley not to the point where you can't hold them.
 
Wow! I came here to post this exact thread for my A60, yet here it is already at the top. :) Ah, well looks like I'm off battery hunting tonight. One question though, what's the life of a good rechargeable compared to a a decent alkaline, eg heavy duty energisers?

Depends on what you're using then in. In something like a digital camera NiMH will last several times as long as Alkalines. Look at the battery comparison link in the thread.

Supposedly the Maha 2200mA AAs are the best ($$$), but I think saw I some Enegizer 2300s the other day at Target. I'd steer clear of the Monster stuff. Costs too much.

I got those. I think it was $45 or so for the charger and four batteries, and wow do those things last. I went on a trip to Ecuador and took tons of pictures, and only had to recharge them ONCE when I was down there. The charger's nice too, it comes with a wall and cigarette lighter adaptor, and charges or conditions both NiMH and NiCd's, AAA and AA. You can even condition two NiCd's in one bank while charging two NiMH's in the other.:)
 
jagec I bought the same thing you did, at thomas-distributing.com right? I got 8 2200 powerex instead or 4 though. I have not had to charge them once since I have had them (about 4 days). Definatly worth the 50 bucks I spent for charger and 8 batteries.
 
I ordered the Powerizer 2000mAh batteries last Staurday, and they came today. They didn't pack them very well, but hey, they are batteries. The one's they sent to me actually were the 2250mAh batteries, which is a nice little bonus. I don't believe it was a mistake, because on the invoice that I printed off and the one in the box (which seemed to be the exact same I had printed off except it had been folder) both said 2000mAh. For $30 shipped they seem to be a great deal.

I just got in on that 24 - 2250mAH, NiMH batteries for $24 from Battery Space and I like them alot.

I charge them in my Rip Van 100 charger that is simply THE BEST battery charger I have ever used. (and thats saying alot cuz I've tried lots of other chargers...)

I really like that charger alot because it doesnt "cook" my batteries like that trash that stores like Best Buy or Wal-Mart sell. those kinds of chargers are litterally killing rechargable batteries because they are charging them with too much current at one time thus making the cells run very hot which just adds insult to injury.

my Rip Van 100 charger knows when the cells are getting hot and it backs off on the charging current until the cells cool down then it goes back to charging them at normal rates. it can normally charge 4 - 2250mAH cells in like 160 minutes or so. it also has the option of discharging then recharging should you wanna run your cells through an occasional conditioning cycle.

as for the Powerizer batteries, yes, they are great. they seem to be holding their charges very well and last quite a bit longer than my 1800mAH cells do.

What is the advantage of conditioning your batteries in this way? In terms of chemistry, I can't see why draining a battery then recharging it would be worthwhile.

It doesn't do anything for conditioning. Discharging is useless unless you want to measure the capacity of the battery. If you keep track of how long it takes to discharge after a full charge you can tell when your batteries lose capacity.
