Battery got extremely hot and was about to melt!
on July 6, 2013
I needed a spare battery for my Olympus E-P3 and choose the Sterlingtrek BLS-1 based on prior good experiences with Sterlingtrek products. My Canon 511 clone batteries worked as well as the OEM at 1/4 the price so I was sure this BLS-1 clone would deliver more of the same.
Popped it in my Olympus charger and a couple hours later was ready to rock. I stepped out for a shoot and an hour and 30 or 40 pictures later, noticed gritty looking images on the display. The grip and battery door areas were really warm. I figured something was amiss and opened the battery door and was horrified to find the battery extremely hot, likely just short of meltdown or worse. I pried it out--it was slightly swollen--and suspect I pulled it just in time. Let the E-P3 cool down for 30 minutes, installed the OEM battery and continued shooting with a cool and well functioning camera.
Sadly this lapse in Sterlingtrek quality control seems to be more than a mere fluke. I also just bought a Sterlingtrek LP-E6 for my 5D MKII and, while not suffering overheating, it doesn't hold a charge for more than a couple days. Sheesh, every manufacturer slips once in a while but two lemons in a row really raises a red flag. So this dawg is on its way back to Amazonville. I'm sure if I bought a few more I'd eventually get a good one--many reviewers certainly did--but with two strikes I decided to walk and bought an OEM battery.
To add final insult to injury, I was accessed a "Restocking Fee Refund Deduction" of $2.40 after I returned the battery, albeit I explained it overheated and was defective. I assume the vender, STK, is responsible for the fee and all I can say is Sterlingtrek lost a long term customer due to poor quality control and crappy customer service (restocking fee for defective battery). I complained to Amazon and they retracted the restocking fee but, sheesh, STK needs to improve or they'll be on the skids.
