So after reading a bunch of positive reviews, I decided to give Sterlingtek a try - I ordered a charger and a battery for my Canon T1i. I was so excited that I got it for a fraction of the cost of a genuine Canon battery! When the order came today, I put the Sterlingtek battery into the charger it came with and instantly the light turned green w/out charging - tried it in the Canon charger and it instantly started to charge. Doh! Defective charger... Called customer service (which was great) and said they would send me a new one and asked me to send the bad one back. Ok, I thought, no big deal.
When the Sterlingtek battery charge was complete, I put my hand to touch it and noticed it felt a little warm. Kind of odd I thought. Pulled the battery out and started to slide it a little into the camera and noticed it was a tight fit (It fit ok prior to the charge). Looked at the battery and noticed that it was swollen! DOH! Defective battery....
I learned my lesson.... Don't get me wrong, I am not bad mouthing Sterlingtek, the customer service was great. I am just disappointed that BOTH my items I received were bad. I guess I am just a few of the unlucky ones..at least I didn't put the battery in the camera and get it stuck..would have ruined my camera....! Hopefully, I can just return my items for a full refund.
