Title: Anyone use Energizer AA 2500 mAH Nimh's
Post by: gewwang on January 11, 2005, 12:12:21 PM
Wondering if anyone has used these. I'm happy with the PowerEx 2450 mAH AA's I've been using but these are rated a little higher.

A 4 pack with a non-smart (at least I assume it's not smart) charger is only $17.99 at Target this week. I picked one up but haven't opened the package yet.

The only downside I see is that I found a site somewhere that said the charge time was 8.5 hours. My maha smart charger can charge 4 AA's in about 1 hour. But the maha was about 4 times the price of this charger. The energizer charger is a more compact size for travelling though.

At the CES convention I talked to a couple of battery vendors including Lenmar. They both say they are going to be releasing 2700 mAH, in the next couple of months. I am running 2450's and cannot justify buying new batteries just for 50 mAH.

George,

I have used these for awhile now they seem to work great .Mine never take more than hour to charge usually like 20-30 minutes..I ran a brand new set for clutch 1hr40mns with my light on and it didnt even lose a full bar on the D100..Hows the job offer going and when we gonna hit a show??

So then you fast charge them wth your maha smart charge or am I missing something here?

I've actually only used the maha charger with lenmars. I was just inquiring to see if anyone knew anything about the energizer charger and batteries so I can figure out if it's worth keeping as a 2nd charger or not.

Which of the energizer chargers do you use? They have 5 types:
http://energizer.com/products/rechargeables/sizes.aspx

The one in the target deal is the compact charger and their website confirms it takes 8 hrs to charge 4 2500mAh's. Definitely have to return this. I'm going to wait for the 2700's LEDZEPZOSO mentioned.

Still interviewing. I'm going to find out about a couple projects this week, none around here though. I have nothing planned before the Crue next month.

I've gone from three preamps to one. I still have the sonosax and the aerco is currently undergoing some R&D. If you have a show coming up before Crue, you're welcome to the sonosax.

I just bought the energizers before I left, target had the 4 pack and a smart charger which you could buy seperatly which is an option.  I am curious how long these guys or even the lenmars run in an mp-2/mixpre so I can get an idea of how long I have before I have to switch batts at a show.  thanks.

They won't power an MP-2, mix-pre, or FP-24 unless you have Sound Devices mod the unit to accept rechargables. Has something to do with the battery tabs on the unit itself being incompatible w/ rechargables.

Welll...maybe.  I believe at some point SD starting including the updated springs/tabs in new MP2's (and possibly MixPres).  Forgot with which serial number it started, but I remember seeing one.  At any rate, yeah - if the rechargables don't worky, you'll need a quick fix from the SD folks.

Bummer, man. I'm in the same boat. I've got an FP-24 here too that I use to stealth on rare occasion. I've been using lithium batts. They get me through 3+1/2 hour shows no prob.

Let me know if SD is at all responsive to modding your "Shure"  device.

+T coming atcha.
