batteries

[haroldenzo]

the battery that came with my angel 1 just died. It died a little sooner than i expected but that's not too much of a problem. Anyways, what kind of batteries are you guys using after it dies? I'm going to order more angel batteries but until I get them I just thought i'd ask. thanks

doesnt really matter. just get good quality 9 volts

[Bleda]

Energizer, Duracel, Rayovac any good 9v will work.

Be careful when using rechargees. Many of them don't have a very high capacity. They appear to be full (volts) but when a draw is put on them the current drops like a load of bricks.

Best to use a rechargeable battery that is made for high load digital cameras and other such devices.

Wow, someone was taking notes

[mike and ikes]

yep.....

yes i made sure to get the high power, i think 150 mAh for the 9v Ni-MH, and 2500 mAh AA Ni-MH batteries for my loaders.

Ok guys,
The best choice is a Primary Lithium Battery 9V 1200mAh Compatible with Energizer L522 9V battery and Ultralife 9V Lithium I believe this is the same battery that comes with an A1 but don't quote me on that!

These are very high in capacity.

Next is:
Rechargeable Li-ion battery @400mAh. This type of battery is used in laptops and digital cameras. You need a special charger to use them though. The potential for explosion if you do not use the proper charger is very high. Excellent flatline output.
See: [URL]http://www.batteryspace.com/index.aspPageAction=VIEWPROD&ProdID=2644 (http://www.batteryspace.com/index.aspPageAction=VIEWPROD&ProdID=1618&HS=1)

I should note that the second battery needs a special charger! Not any charger will work with them. The potential for explosion is very high if the wrong charger is used. Additionally, these battery's are pretty close to flat line on there output. So that means that when they run out of juice they just stop. So you really have no warning that they are low on power storage. They will just all of a sudden crap out. Best way to use them is to run them X number of hours and swap them out for fresh ones.

Before you use this type of battery it would be wise to read up on their usage and charging procedures. You can damage them if not used properly or you drain to much out of them before recharging them causing permanent damage to the cell.

EDIT: corrected my post from wolfram075 comments! He is quite correct in his observation, nice catch mate!

fyi the primary lithium battery that is listed is just that a primary cell non rechargable battery... it sez right at the bottem of the page in bright red letters not to recharg it... here is the link to the hights rechargable 9v that i could find...with a google search.

Any thoughts on this one?

Pros, cons, etc...

[wolfram075]

looks even better than the one i found....and limh usualy has better performance than nimh...flatter discharge and more memory resistant

Trigg,
Nice find! Li-po's are the absolute best for batteries. Again they use a special charger. If you use any other charger they could potentially explode. But they also flatline on output until exhausted. So you need to be careful on the length of time you use them. They will seem fine and all of a sudden just drop out. I would think they would be fine in the A1 for 4 or 5 cases and I would then swap out with a fresh one. You can damage these by drawing to much out of them.
I use Li-po's in my Halo's 2500 mAh @ 11.1V. But the current they put out is a big factor so they need to be regulated down for voltage and amperage. Yes these pack quite a punch! For short bursts they can easily output 60 amps. Yes that is Amps...... So just hooked up to a Halo alone you have blender dejoir!
