battery wont charge but the mac Power Up, after repairing the magsafe

I have repaired the magsafe connector many times, but yesterday I was repairing and accidentally reversed the polarity, and plug it into mac while it was running from the battery. it did not do anything like a spark or shutdown the mac, and the Orange LED did not turn on. So, i thought to check the polarity again and it was wrong.

Now the mac powers up from a charger but it does not charge the battery,

I check the battery it has 270 cycles on it and it is recognized by the mac, and i used another new charger an it is the same.

So i was wonder if anyone had the same experience or knows anything about this,. I am not sure if the DC-board has fuses or anything that could be fixed.. Please tell what to do .. Thanks
