kenshin9 Posted February 2, 2007 Report Share Posted February 2, 2007 so yes i got a battery with a gun i swapped ages ago, but i have no idea what the Mah is on the battery so i cant calculate the time i need to charge it, the sticker on the battery has come off, so i dont know what it is. Also i dont have a charger with the auto turn off function thing on it and need to charge it for tommorow lol. any help would be greatly appreciated thanks Jas Link to post Share on other sites
Sao Posted February 2, 2007 Report Share Posted February 2, 2007 The short answer is no, unless you have a charger that can charge to a peak and then discharge so you can read the mah coming out of it. Link to post Share on other sites

Sao Posted February 2, 2007 Report Share Posted February 2, 2007 Well, if you can charge it up to it's full capacity and then stick a 1amp load on it you could time it to see how long it takes to go flat, that'll give you a rough idea of the mah rating of the pack. I.e if it takes 1 hour to discharge then its a 1000mah pack (or thereabouts) This is assuming you access to a multimeter though.... Link to post Share on other sites

RaboonTheBaboon Posted February 2, 2007 Report Share Posted February 2, 2007 Is it impossible that the cells themselves might have the mAh written on them? I've got a battery that is wrapped in clear shrink wrap, and the batteries below have "2000mAh" on them. I don't know if this is just the design of this battery, with the rating etc on the cells - you might find you've just got unbranded ones under there but it might be worth a try (without tearing the battery to bits of course!) Good luck. Link to post Share on other sites
Docv400 Posted February 2, 2007 Report Share Posted February 2, 2007 I think you're right Raboon, all the single cells I've seen have the mAh rating on them...sorry Kenshin, I didn't think of that when you asked me before. Link to post Share on other sites
kenshin9 Posted February 2, 2007 Author Report Share Posted February 2, 2007 nope nothing on the cells either... thanks for the help so far Jas Link to post Share on other sites
Sao Posted February 2, 2007 Report Share Posted February 2, 2007 How old is the battery, what size, do you have any other packs to compare it to? Did it come with a gun and was it the original battery supplied with the gun Chances are if it's a small old pack it'll be 600mah Sanyo NICADS like you used to get as stock with most old TM guns. If you compare it to a known type of pack of the same size is it lighter or heavier? In my experiance Nicads are usually lighter than Nimhs of equivalent size. But really all this is guess work A Picture of the battery might help Link to post Share on other sites

Sao Posted February 2, 2007 Report Share Posted February 2, 2007 size its the normal for an 8.4 so 7 cells. Nooo I mean are they sub c (std /big/ packs) or 2/3rd AF (the small or mini packs), Physical size I guessed it'd be a 7 cell pack Link to post Share on other sites
kenshin9 Posted February 2, 2007 Author Report Share Posted February 2, 2007 lol.. oh.. its a mini for my M733 Jas Link to post Share on other sites
Sao Posted February 2, 2007 Report Share Posted February 2, 2007 My best guess then would be a 600mah old Nicad or if its newer an 1100mah Nimh Got any other mini packs to compare it to? Link to post Share on other sites
kenshin9 Posted February 2, 2007 Author Report Share Posted February 2, 2007 yep i got one on discharge now. i might just go with teh guess of 600 mah tbh. and if it shooting slow i'll charge again with it a 1000 and so on... thanks for your help Jas Link to post Share on other sites
RaboonTheBaboon Posted February 2, 2007 Report Share Posted February 2, 2007 Kenshin, just to make sure- mah is how many rounds you're gonna get from it rather than the ROF of your weapon, so if it potters out at about half a day's play, not too heavy on the trigger finger, you're probably looking at a 600mah. Hoping you can find it out from a more substantial test at some stage though! Link to post Share on other sites
