You will need gauge 14 cable and connector for the battery side.

KTX Battery

If you have been using the battery for a year, it might be the time you would need a new battery.
If your battery stop charging, you can try draining out all the charge and charge it back for several times.
Then,  if your battery still doesn't charge, it's the time to get a new battery.

 Also, you might want to check on the battery charger.... if it's charging, you should see red led light on.
If not,your charger is not working properly.
