Pentax Dli90 or third-party battery?


For my k7 camera+ grip I am considering a spare battery set. (I now have one pentax battery and two third-party batteries) What would you advise me to buy? Are the Pentax batteries more reliable, more powerful, faster charged or slower discharged?
Or is the technology of the batteries so universal that getting a third party battery somewhere on the web won't hurt my k7?
Thanks for your advice!

Pentax batteries are third-party, just rebadged. You'd (maybe) be amazed how many things are really the same ones in a different package.

For my K20D (different model battery), I got a Lenmar for about $16. No complaints.

I have used many manufacturers and after market batteries in a variety of cameras and I have never seen a difference between either types.

The only difference I see in the D-LI90 is....

The Pentax branded batteries show a voltage rating of 7.2 volts. Most of the 3rd party batteries I see are rated at 7.4 volts.

Shouldn't make any difference.

Although I don't specifically have one for my K7, I've never had any problems with third-party batteries in the past.

I have a cheapo (1/5 of the original) china made and works as good as the OEM (charge hold, number of actuations etc). Cannot say if it will go South faster than the original.

Your choice

Good to hear. I just a bought a Pearstone battery, 7.4V, 1700mAh. The Pentax is 7.2V, 1860mAh. I was wondering about the difference.

UPDATE: The battery won't even take a charge. Back to B&H it goes. I think I'll just shell out for the Panasonic.

After procrastinating since buying my K10D late last year, I just ordered a backup battery from my favorite online vendor, I've got a "Prime" account, which allows me no-charge shipping on any item that qualifies within the amazon site. So, for about $13, I'm getting a BP-L150. If it performs well, I'll probably order another. I also have large capacity battery paks that can supply any of my cameras. But honestly, I don't need much more than what a fully charged internal battery can supply. And since buying the K10 late last year, I've never run out of battery power in the field. Nice thing about Amazon is that they stand behind any purchase. I believe this particular battery has a 1-year warranty. So for $13, and free shipping, I'll take my chances on getting at least one year of service.
