shove it up your bum lol
You have to buy a new battery. There is a few ways to repair one. It depends on what you did to it. I recommend a standard 8.4 volt battery. It has a decent fire rate and is affordable
It sounds like you have either a low battery or a broken gearbox. Try with a fresh battery, if that does not work, take it to a repair shop.
Take it to a qualified repair shop
platinum auto motive by far I highly think they are the number 1 in Michigan
Best left to a trained technician
Probably a problem with the gearbox. I would send it to an airsoft store/ repair shop and have them work on it.
Needs repair work
An air conditioning unit that does not blow cold air definately warrants a repair. With central a/c units, they do not run on a battery, but are powered by electricity. Mobile units may need repairs too, and will be cheaper to fix.
If the battery is damaged replace it. There is no way to repair that damage.
Take it to a trained repair person.
You leaf it alone!
In any electrical device, feeding an amount of voltage which is greater than what it was intended to use is prone to causing damage to it. If your airsoft gun came with a 1.2v battery, it was designed to be fed from a 1.2v current, and placing an 8.4v battery in it will cause it to feed from a current seven times greater than what it was intended to use. This creates a risk of overloading the motor, which, for electric motors, typically causes it to burn out. This creates heat, naturally, which can also have the effect of melting down the materials used to manufacture your airsoft gun (as far as I know, they're mostly made of plastics), which will render it not only inoperable, but also damage it beyond repair. So, the short answer would be no, and you should use only the recommended battery for your airsoft gun.
