--------Which brand is 'best' for 15 Minute Rechargeable Batteries?

[thatsright]

Need to get some rechargeable batteries to replace the ye ole AA's I have. Anyone use the Energizer or Raovac 15 Minute chargers?

And anyone know of a reliable place I can get them for cheap online?

Thanks a lot!

Battery Space will sell you a huge pile of batteries and charger for a song. There's no reason to charge 'em in a hurry, when you have a bunch all charged up and ready to go at all times. Besides, fast charging heats 'em up, and shortens their life.

:thumbsup:

One question: what's the difference between a "smart" charger and a "non-smart" one?

Sounds like marketing hype to me. I think all Ni-MH batteries require what would be considered a "smart charger". It varies the charge based on the battery's current charge condition.

Edit: Why am I guessing?

By reading it, the non-smart ones work on a timer to charge, and the smart ones stop charging when they start getting current from the batties.

Nice post, I had the same questions

 

[Ornery]

I'm pretty certain that a Ni-MH battery can handle both Ni-MH and Ni-Cd batteries, but not the other way around. A Ni-Cd charger won't bring the Ni-MH up to capacity.

its rayovac ic3. only the ic3 batteries do the 15 minute charge. supposedly theres a circuit or something in the batts that allows for better monitoring during charging but i think it can be worth it. turns charging into something one can do at the last moment... or simply takes away the annoyance when u run out and need batteries.

go to dansdata.com if you want info how how batteries are charged. all chargers are somewhat "smart". use his search feature.

Am I able to use NiMH batteries in place of alkalines? (1.5v vs 1.2v)

 

[0roo0roo]

in most applications yes

Would it just draw more from the rechargeables?

(I am thinking of getting some for the wireless keyboard and mouse, CD player, alarm clock, etc.)

For some reason, in certain items I have had very poor results with NiMH batteries and in others I've had great results.

My simple wireless thermometer (indoor display is AAA, outdoor transmitter is AA) will run for only about 20 days on a fully charged set of NiMH batteries, but the NiMH batteries more than doubled the playing time of my portable CD player.

I'd stick with Alkalines for things like digital clocks, and use NiMH only in high-drain devices like CD players. That's how I've had my best luck.

just go to dansdata and search on all the terms you can think of.

the slower the drain the worse it is for rechargables since they lose ~1% a day regardless. some..very few devices require 1.5v instead of 1.2v and can't use rechargables. my mx700mouse uses nihms just fine. it has a charging cradle though. when i had an older version i just kept a 2nd set on charge, the older ones had lower refresh rates and the nihms would last for weeks unlike the mx700. stuff like fire alarms etc u use alkaline only.
