One of the contest winners at Grandfather Mountain this weekend was shooting with a borrowed camera because a third party battery had fried the mother board in her camera. I don't think she was a Pentax shooter.

I've had a DLI90 battery swell on the flat sides and get jammed inside the camera. So I first googled and found out what was inside the plastic shell. Found it had two Lithium cells connected to a tiny motherboard sitting on top. So using a drill without caution would go through the motherboard and perhaps cause problems. So I used a craft drill with a 2 mm drill bit at slow speed. I wrapped a colored electrical tape 1.5 mm from the tip which was about the thickness of the battery shell. Drilled gently to puncture the shell without touching the motherboard. Bent 2 #s 2 mm thick steel strip into L-shape and stuck them on top of the battery in a T-shape with Araldite Epoxy - slow curing type. Let it to cure for 24 hours. Then drooped just a wee bit of Singer Sewing Machine oil on both the sides. Grabbed the steel strip and slowly pulled out the battery. The battery shell was swollen on the camera contact side. Before scrapping it I dared to charge it on a cheap ebay charger. Then checked the voltage. Eureka 8.4 volts. Checked for heat build up and there was none. Peeled the sticker on the swollen contact side and rubbed it down on an Emery Sheet. Put it inside the K-5, and voila the camera showed Full Charge and it was working. Better sense got hold of me and I scrapped this 3rd Party 3-year old battery. Had won it on an evil bay bid for $ 3.99. Lesson learnt - use good quality stuff like DSTE or Wahabi for $ 6 to 9. Note: I have used some (9) #s 3rd Part Batteries on my K-20D, K-5 & K-5 IIs with just this loss. Regards. Bipin Photography focuses you to see things you may not notice otherwise.
