This is bad. I'm guessing you didn't use a smart charger. Basically, using it won't destroy your gun, but don't count on it helping you out. Buy a new battery. It's a lot cheaper than getting new internal replacements. And get a good charger. Don't skimp on that.

I have a 'PIRANHA DIGITAL PEAK CHARGER' $65US. It does everything well, but doesn't have a discharger built in. You can usually get one for around $15US if you look around. It's important to remember that your batteries worst enemy is heat. Your battery will heat up as you charge it. The higher the current you send to the battery, the hotter it gets. Conversely, the lower the current you send, the cooler, but slower it charges. Also, a smart charger can automatically regulate this and you can alter the sensitivity to allow it to get to maximum charge more accurately, but also slower.

Basically it all comes down to time. The slower you charge your battery, the better life you get out of it. If you cannot set things like current, sensitivity, and capacity on a charger, I wouldn't get it. Good chargers will stop sending a current when full charge is achieve, and/or will only send a very slight current (trickle).

Brand? Forget brands. Look at features instead.

What you want is dummy-proof, guess-proof battery charging and maintenance. For that your choices are limited. You want a computerized type of charger that will slow charge, fast charge, discharge and have a clear display to tell you the voltage and amperage. Such a charger is expensive, but if it keeps a pair of $80 to $100 batteries working for over 3 years it pays for itself.
They cost between $150 to $200. No need for the funky Marui one that is more expensive. Avoid the cheap crappy $20 chargers.

After that, just read the instruction manual and go play with no worries. Have fun.

What kind of battery do you have? Voltage? Capacity (mAh)? Picture if you don't know might help us help you.

ill try to take a picture, but ill write down what it says on each battery first:

KR-600AE 1,2V ,600mAH

its seven batteries linked together

a pic that shows how they look atm. Notice at my finger, im holding the plastic down to show how the rift in the plastic is, and u can see some spots of metal cuz the stuff on the batteries got rifts too...this might also be cuz i had a hard time getting the batteries out of the gun, but i doubt it, since i didnt notice anything at that point..


*EDIT* seems to me like the batteries has expanded or something?:S

Yeah you cooked it, from what I can see the charger outputs for 1300 mah-3000mah, your 600 mah battery got over double the charge that it needs, thats why it pretty much melted.

I'm not 100% sure about the usage of your charger, but that 600 mAh is what the dial on the right of the first picture should read. Unfortunately you don't have that as an option, and your lowest option is way too high. What your charger is trying to do is your battery over double what it is rated to. If you didn't catch your battery when you did, you would have probably started a fire. Basically it's like an automatic gas pump trying to fill a 10 L tank to 20 L, but in this case with electricity. Not so good. You are definitely going to need a new battery. If you want to use your current charger, you can (I would not recommend it), but you have to make sure that you get a battery that matches one of the settings on the right. For example, if you get a battery that is 1400 mAh, it will work, but you would always have to use a lower setting, or risk the same thing happening. This would also mean you wouldn't be able to fully charge the battery. It is possible, but again, I don't recommend it. You should probably get a new charger.

Also in the specs you sent, you didn't say what the battery's voltage is. It should match one of the settings on the left side of the first picture.

the batteries are 1.2 V each, 7 is 8.4, so if u had it set to 8.4 you had atleast one thing correct, and If ive deducted correctly, that charger is way to powerfull for your battery.

Ok, you are in Norway, and the battery specs you did send said 1,2. That means 1.2 to us. If there are seven 'little batteries' in the pack, that works out to 8.4 volts, which is what the left side should be set to. Either way, you need a new battery. If you do plan on using the same charger, just make sure your capacities match.
