722 battery
« on: January 28, 2008, 03:27:34 PM »
So as far as "on unit" batteries go, is this one still the largest capacity/best deal/reliable performance?

i'm sticking with the name brand. i had a female contact sleeve come out of a no-name variety. this is not scientific, as i'm sure the chassis was made by the same people, but it only takes one fuck-up for me.

i had a genuine sony die on my recently - i think most of the contact issues have been resolved with the generic brands, but its clear than neither is without some issues

This has happened to 4 of my batteries, i now have two for traveling on airplanes that I have superglued the contact in place.  let it slide out a little, apply some CA glue and press the contact back in.  I have not had any problems using this method, when using these batteries i cycle through them and charge w/ an external charger.  

The packs i got are from 1800emart.com

I bought the B&H and it works fine.  I have had the female connector pull out of the Amazon batteries.  I returned one.  I am not sure if I want to return another.  I suppose I should.  And I will super-glue (CA) the female connector in first thing.  B&H is less hassle.

One of my generics, the case actually cracked. No problems with the sleeves :laugh:

I think I'll go with the Impact from B&H. Assuming Impact is not generic. I think my charger brand is Impact.

Same here. The Impact batteries have been bulletproof for me. I got 2 Impact 7600mah, a 6600mah Sony, and a 4500mah that came with the 722. The Sony's blow (and don't fit because the pin sleeves are too shallow!), I am on my 2nd one of theirs and I get MAYBE 4 hours with phantom at 24/96 on the 6600mah, whereas the Impacts give me about 5.5+ hours minimum each.

What is CA glue?

CA (cyanoacrylate) = super glue

Buy it at your local hobby store, you get 2oz for the price of .1oz at the hardware store.  as long as you keep it sealed it lasts for years

Thanks Fozzy!

FWIW, the amazon links to some batteries that are supposed to be 6900 mAH. I went with the cheapest model from Red Hot Buys and they ended up being only 6500 mAH. I'm going to keep them at only $25 each, but buyer beware.

Use your savings to pick up one of these:

http://taperssection.com/index.php/topic,85329.msg1217458.html#msg1217458

I got this and there are no instructions in the box. Does the 100% blink when fully charged or does it stay solid or turn off or something?

Blinking = charging.  Not blinking = done.  The lowest solid block is how much it's charged.  For example, if the 50% block is solid and the 75% block is flashing, it's 50-74% charged.

Great charger, BTW.  Turns out my previous battery woes were related to the charger, not the batteries themselves.
