That means it has low resistance, or you had a short curcuit that it burned up. Your battery may not be good anymore and needs to be desulfated, which I can show you. Here is cheap charger to replace the one you mentioned.

Not a really good idea. You need to limit/control the current flowing - The voltage should be around 8 volts to charge a 6 volt battery
