Hey all!

I'd love to get some recommendations from y'all on a *very good* charger and some rechargeable 9volt and AA batteries.

These would need to be performance quality: lapel microphones for speaking, wireless headset microphones for singing and such....

I'd love to find a charger than can handle at least 2-3 sets of 9 volts (4-6 batteris) + 4 AA batteries, if such a beast exists.

I've heard about these I3 batteries, I think from Energizer or something...would these be acceptable?

They need to have a good lifespan and have a high recharge capacity (can be charged lots of times).

What do y'all think?

Randall

Why not just use Alkaline for microphone?

As for charger, you should stay away from fast charge. You can't have maximum capacity, maximum cycle life and charging speed all at once.

This is great!

thanks for the replies.

I've heard good things from Thomas Distributing before...and this confirms their reputation and product recommendations.


NeoPTLD: In response to your question..we're going through ~ six 9volt and six AA batteries a week. That adds up VERY quickly, hence our desire to go with rechargables. While the initial cost is higher, it'll work out to a savings overall.

Also, in response to NeoPTLD's statement about staying away from fast chargers....*why* can't you have all of that at once? Most of the chargers offered on the Thomas distributing site are fast chargers....


Thanks y'all!

Thanks for the second suggestion, dartworth!

One other question for y'all, would you trust these "PowerEx" batteries at Thomas Distributing or "Powerizer" from Batteryspace.com in expensive sound equipment (microphones/battery packs)??

Because like everything, it is a tradeoff.

Charging the batteries fast means pumping lots of current into them. Pumping lots of current into them produces lots of heat. Heat shortens the batteries life.

There is a difference between a down and dirty fast 30 minute charger, and an intelligent fast charger like Maha's units.

Further, I always just use the slow setting. Sure, it takes longer.. but the batteries barely get warm to the touch, and if you do it while you're sleeping.. it doesen't matter. This will result in many more available useful charge cycles. Remember that it is good to let the batteries sit in the charger for a while after the green lights come on. The "main" charge can only get the batteries to something like 95% of full charge. When the green lights come on, the current slows to a trickle. This fills the battery up to 99 or 100% capacity.

The Powerex are supposed to be the best. I use them in my Canon A60, and can get hundreds of pics, even with the flash. Around 3 - 500.

I'm glad this thread came up... I bought a bunch of powerex batteries with a friend about a year ago, and neither of us had any luck at all with them. ???

I realize this is contrary to most people's success.. but I bought them primarily to use in my cordless keyboard / mouse and remotes, etc, and I basically gave up on them entirely. When I first bought them, I charged all of them... put a pair in my mouse and after about a month they died...went to swap in one of the other sets, those lasted about a week. (after sitting unused for a month)

Now, the only other conclusion I can come to is that my charger is no good (it's a radio shack one, a few years old, switchable for nimh or nicad) but I've had other brands of nimh before and never had any complaints... plus my friend had the same experience with his batteries...

Rechargable batteries are NOT good for low drain devices like remotes, clocks, and I imagine cordless mice/keyboards. Unlike alkaline batteries, recharables lose a percent of their charge every day, whether they are being used or not.

Your batteries were probably only 30 - 40% full after sitting for a month.

If they have never really been used, there is no reason why they are junked. You also have to understand that it takes a few cycles to get the batteries broken in, so to speak, and for them to reach their maximum charge potential.

It is probably your charger that is the culpret. It would be better to skimp on the batteries than the charger, as it is up to your charger how well the battery charges, not the battery itself.

I do know all these things, but it was still an unusually bad experience with them. I've used other NiMH batteries before and never had such annoying results. I do recognize that they excel in high-drain applications, NOT long life ones... just sharing the experience. I'll have to look into getting a different charger and see if that changes things...
