Mid-2009 13 inch MacBookPro 5,5 doesn't like new ANKER battery. Faint Green light

Hello all
During Sep 2014, I noticed, on one day, that the Mac would not start. I discovered that the battery had swollen up. I removed the rear lid and disconnected the battery. I did not have the tri-wing screws so left the battery as such. I am also sure that after disconnecting the battery, the laptop charger glowed BRIGHT GREEN.

I am in India and some relation had brought an ANKER battery (from Amazon; it was rated higher than Apple's own battery) and twi-wing screw drivers from the US.

In Jan, I replaced the battery and upon powering the laptop I noticed the following :
a. The charger had a faint green light.
b. The battery was getting charged slowly.

Satisfied that I atleast had a fully-working laptop I did not use it for another 2 weeks.

I then realized that the laptop would not boot up if I connected the battery.

If I disconnect the batter from the battery pins, it would boot up, but with the faint green light.

So here are by doubts :
1. Is the battery defective ?
2. Why the faint green-light ? Does it need a DC-in board replacement ?
3. The laptop runs on half-the speed without a battery. Is this behavior caused by OS X or is it the way the hardware is designed ? I am willing to install Linux and live without the battery if the laptop runs on full CPU capacity.

My 8 year old Dell and 10-year old Thinkpad T40 are still soldiering on, so I am disappointed that the Mac is dying an early death.

Please advise. Thanks

P.S : Switching to the old swollen OEM battery does not help. The laptop won't boot. And without either battery the charger shows faint green light

Best advice was buy an Apple battery not third party.

I couldn't agree more.

My battery went bad and I bought a NewerTech NuPower battery from OWC,
The battery had great reviews and OWC is a great company. But the battery was no good when I got it. It wouldn't charge at all..I emailed OWC and they told me to send it back and they sent me a new one immediately(again..great company). I get the new battery and one of the wires was kinked, so that one was bad too. I sent it back and got a full refund.. Drove to the Apple store and bought a battery...I wish I would have just done that in the first place and saved myself two weeks instead of $20...
