Battery Issues. Need Help

[GD90]

I rewired my two 9.6 volt batteries to deans as well as my two guns and the charger. I put one on a trickle charger for overnight and when i tested it the next day it would only fire about 50 times before it would die. All the wires correspond correctly with the positive and negative tabs on the deans. I made sure that the battery would not short out when i was switching from tamiya to the deans. I used 60/40 rosin core solder and made it so there was a strong joint for each connection. I did accidently touch the two wires together when the charger was plugged in when i was converting to deans. Im not sure if this affected the charger. Not really sure where to go from here. Any advice would be appreciated.

I don't think that would have killed your batteries, if it were a Li-Po that would have fried them.

What kind of a charger or you using? Just a little black wall trickle charger?

It is a trickle charger that i had recieved with my g&g m16 a while back from buyairsoft. It's a pretty basic trickle charger, nothing fancy.

*smart charger not trickle*

Sorry, trying to make sure I have this right... did you say you crossed the wires of the charger WHILE IT WAS PLUGGED IN? That's a bit strange that you would strip the wires and try to solder on a new connector while it was plugged in to the wall...

Anyway... do both batteries have this issue? Do you have a voltage/multimeter to check the batteries? The "smart" chargers that come with guns are not really smart... they are still just trickle chargers. So was it the charger that came with the gun (regardless of whether it says smart or not on the charger) or was it a different actual smart charger? If you used to charger that came with the gun, what is the output of the charger? What size batteries are you charging?

I was basically checking which wire was positive and which was negative by putting the stripped wires into a a battery with female deans connector. I did not solder the charger wires while it was pluged in. My first two batteries had touched wires so i thought they were fried, i then bought 2 new 9.6 volt 1600 mah batteries. The wires did not touch but it had pretty much the same results as the two that had crossed wires. I do not have a voltage meter. I was charging the batteries with the charger that came with the gun. I am pretty sure the gun came with a smart charger it has the green and red lights to tell if it is charging or not. The charging current is 500 mA

That is not a smart charger. Smart chargers will stop charging when the job is done, deplete it if you want it to, and can sometimes detect if they are full or not.

If you are struggling with this excessively, I would highly recommend taking this to a skilled professional to do this work instead, considering that you crossed the wires twice for some reason. By the way, I believe that this WILL fry your batteries. Correct me if I am wrong, but when you cross the wires, you create a complete circuit which will run its electrical charge. Since there's no conductor, resistors, or anything to use up the electricity (from the full battery) you've likely fried or damaged the cells.

I know that i could of killed those batteries thats why I bought two new ones. I did not cross wires with these ones and they still wont function properly

You have a dumb charger. Don't trust the chargers that Toronto Airsoft provides. They do not even work properly.

Can you show provide a link or picture of your charger?

Ummm he says he got his stuff from BuyAirsoft....

those plug in wall chargers are pretty shitty... but nimh packs are shitty too.. there's probably a dead cell or two that won't hold a charge that's really fucking shit up. Without splitting the pack and measuring each cell individually you'll never know.... and that's not something that's recommended for people who don't have the right tools to solder it all back together.

nimhs seem to have a shelf life of being empty, sometimes you can kill them when you let their voltage drop too low... they just won't come back.

Oh oops, I bought a G36 for my cousin at TA last time, the battery almost caught on fire when charging it with the wall adapter. Just saying.

Pictures are worth a thousand words... so please post some of your soldered connections.

As stated, despite what is written on the charger, what you have is NOT a smart charger.

This is a smart charger



You need to get a simple multimeter ($30 at canadian tire), it's a must have for any electrical work. Also, next time you need to find out positive and negative wire... look at the connector. Even if the charger wires don't tell you which is positive the battery wires typically do. Plug the two together and bam! you know which is the positive wire on the charger.... Then may I suggest that you only do 1 wire at a time? This removes all possibility of shorting wires. Cut positive wire, strip wire, solder, put on shrink tube then cut black wire, strip, solder, shrink tube.

In the end, I'd suggest you try charging for a longer period of time, sometimes the first charge needs to be quite long.

The JG G36c? The wall charger worked fine on my unit. Charges, shoots, indicates red/green light when charging. They don't stop charging when it's complete (green light), so if you kept it in for over 9+ hours, that might be why it exploded and burst into fire.

Try a new charger then. If it still doesn't work, do a check of the fuse, wiring, etc. You said you rewired the gun to deans, how do you know that it's the battery malfunctioning and not the wiring?

Yup, you really don't wanna leave these things plugged in too long. Well it wasn't me.

I have a IMAX B6AC, and a APEX Advance Avionics.
