Battery Diagnosis.

[Tweak]

Hey guys, had a quick question to throw out there for you all.

I just recently started a new job, working with an Airframe service place. One of the many perks is I get a really nice discount on airframe parts. Why someone would have a use for them I do not know, but I have found a few usefull bits and pieces.

Bits like these batteries laying on my desk. They are covered in a white film, presoldered tabs included, plus and negative clearly marked and prepped for making what I think would be a very nice reciever pack. I have about twenty of these batteries in all, bought em for 5 bucks after someone dropped the box and they were unable to identify the batteries. The one and only marking on the batteries themselves are "74025, 38925-004, and 0850"

They all seem to be in good shape and I would really like to know more about em.
This is where the questions come in. I know they are rechargeable, I know they are quite powerfull (1400+ MaH range, definately) and I know I would love to solder two together into a pack and use it for my reciever.

Is there any way to tell what MaH rating a battery has? If so, will too many MaH's kill my reciever or cause other adverse reactions?

Again, i have a LOT of these things and can redily get more, I have seen some in the clerance bin that I would love to get my grubby hands on, MaH ratings I have never seen before.

Any information would be greatly appreciated

Does your charger show the amount charged?
If so, drain it and charge it up. It will give you an idea of the Mah it holds. Use a volt meter to see if its 1.2v or not.

If you don't have this equipment I will be more then glad to test one for you and let you know.

Mah ratings will not have any adverse affect on your equipment. Its like the size of the tank in your car, The larger it is the longer it will run between fill ups. Volts is what you need to watch out for.

I don't have a metered charger, but I am looking for one right now. Also, the batteries are NOT regular sized. they are shorter and fatter than normal batteries. About the circumference of a "C" battery but only about 1 1/2 inches long.

I guess I could relate the size to normal pack cells, if asked. the only way I know they are rechargable is the fact that they were on the rechargeable shelf when they were dropped. Eddy, dropp me you address and I will send you some samples.

And who knows, if we both get lucky you might get some free batteries and I might get a nice, soldered, shrinkwraped pack...with leads?
