ICS M4 Battery problem
I have an ICS m4. When I put a 8.4v battery on it, the gun seems to work fine. When I put a 9.6v battery on it, the gun only half cycles almost like the battery is dead and i have to release the spring with the button on the side of the gun. 9.6v is brand new and i just charged it. When i chevk the battery on a volt metre it reads 10.9 to 11.18 volts so that should be full right? maybe my charger is the problem.
Any Ideas what it might be?

His problem is that the 9.6v does not have enough current to drive the gun. It is unsuitable. The 8.4v battery is delivering the current and supplying the motor the necessary current to fully compress the spring prior to releasing it.
It's "possible" that the charger is not properly charging the battery, but it's more likely that the battery is simply too small. But to be sure, you should specify the sizes of your batteries, voltage is only 1 component of size, the other is the current rating expressed in milli-amp hours, or mah.

ploarity is corect on the battery. All of my 8.4v work on this gun, 3000mah, 1600mah, and a 1500mah.
None of the 9.6 Ihave work on the gun, 2 @ 2000mah and a 2200mah. This confuses me. Shouldnt a bigger battery work better not worse?

Your 9.6v are built with "AA" sized cells, correct? Most of the ones I've run across are not well suited for the current demands of airsoft guns. When you compare them to sub "C" built batteries, like your 8.4v, the difference in performance is clear.

Do you have any internal upgrades? If you have an upgraded spring it could be what mcguyver said, but if not a 9.6v mini should still be able to cycle it IMO.

wow i thought bigger cells and more of them should haver mower power. I guess this is one of those times where bigger is not better.
I dont think i have any upgrades, bought the gun used so i dont know whats in it. What battery would you guys recomend putting in it? The battery is stored in the front grip. some day i wolud like a crane stock, but i would like to wait untill one is available where you dont have to mess around with pluging wires inside a buffer tube. something like on the tm sopmod.

Use a mini 8.4v like you have been.

what should a full nunchuck battery, 9.6v 2000mah with the aa size cells read if it is fully charged and checked with a multi metre?

It should be higher than 9.6v, perhaps as high as 12V without a load. As soon as you apply load, it will drop to around 9.6v and stay there. If it drops below that, you have a problem.

Sounds like the wrong type of batteries for an airsoft. I had the same problem with a Crane Stock battery pack. Fully charged (no load reading 10.8V) and it had less than stellar performance on my M4.
It was a 9.6V, 2000mAh, Sanyo enerloop (AA size). These things should NOT be sold for airsoft. Batteries actually have THREE specs 1) voltage 2) current (mAh) and 3) discharge rate. The last is directly related to the battery's internal resistance. Commercial size batteries typically have poor discharge rates/ high internal resistance. Performance batteries have high discharge rates/ low internal resistance. Some of these can deliver burst currents as high as 25-30 amps (25000-30000 mA) with a rating as low as 2000mAh. Commercial stuff is typically as low as 5-10 bursts. So beware what you buy... A good source and education can be had at cheapbatterypacks.com
