Re: Experience with third-party batteries
At one point I did a test where every time I'd change batteries I'd take a photo of the battery I had just replaced. By using the shutter count I'd have an idea of how many photos I got out of each battery. In short, on the K-5ii(?) I saw no significant difference in performance between pentax branded and cheap batteries, and no I don't remember the brand. I've noticed that the K-1 uses batteries up a LOT faster. My thought is that third party batteries are really cheap and bringing a couple as spares doesn't add a whole lot of weight in your luggage and can make life a lot easier if you don't actually charge everything up the night before, or you lose one. You don't have to carry everything with you in your backpack all the time. Mark Roberts wrote: Can anyone recommend options for third-party batteries for Pentax?

Re: Experience with third-party batteries
It's used, and they're showing a stock photo. I wouldn't buy it either.
The issue with lithium rechargeable is that they age from the date of
manufacture. Charging cycles have much less effect that on other
batteries with other chemistries such as NiHM or NiCad while simple age
will effect them much more.
You really want to get a newly manufactured battery.

Re: Experience with third-party batteries
I have a Watson branded extra battery that I'm using in the K-5II the specifications were a bit better than the Pentax branded version that came with the camera and I haven't noticed any real difference between the two batteries. They both hold a charge about as long and I get a similar number of exposures per charge. On the other hand I have a Flashpoint branded DL-I50 for the K20D which from it's purchase had noticeably less power reserves than the Pentax branded battery that came with that camera, despite also having better specifications on paper. Using the K20D I don't ever remember running out of power with the OEM battery during normal usage, and the spare was only there to be used in a pinch. Sadly I think that brand names on third party, (unless you're buying a big brand), batteries are kind of a crap shoot. I've read reviews that show the exact opposite of my experience with those two brands. On 3/5/2018 8:50 AM, Mark Roberts wrote: Can anyone recommend options for third-party batteries for Pentax?

Re: Experience with third-party batteries
Mark, I've been using several D-L190 s from Watson for several years and haven't noted any significant differences relative to the Pentax battery. I haven't done any objective testing but I have no reason not to buy more if needed. Mine are around three years old and still going strong.

Re: Experience with third-party batteries
I wouldn't buy that battery unless there is a reliable full-refund return
policy (like with Amazon Prime). As the proverb says: "I am not rich
enough to buy cheap things".
A lot of stores are sloppy with posting specs and photos of their
products, especially small accessories.
Zeikos battery that I bought from Buydig was listed by BuyDig/BeachCamera
as being a 3.7 V battery (as opposed to the OEM rated at 7.2 V) for a long
period of time, even after I've shown them a proof.
I've posted that story back in 2011 on this list:
http://pdml.net/pipermail/pdml_pdml.net/2011-May/277442.html
And that store was considered one of the better once, at least back then.
(I thought it slid down since then, but resellerratings still rates them
at 9.5/10)

Re: Experience with third-party batteries
I can only disrecommend, but that's based on a single try.

Then it faded really fast after 10 months or so and wouldn't take a charge at all. Back to OEM batteries for me after that. Damn, they are pricey. They are $90 Can here.

Third Party Batteries
I am certain Auld Tymer Digital PDMLers would have had an over dose of this topic which is on some (20) World Class Photo Forums like Pentax, Photo Camel, DCRP, Shutter Talk, JJMehta etc. 95.70 % of the folks have said 3rd Party batteries are just as good, as long as you buy them from good sources like Amazon, Adorama, Battery Fly com, Energizer etc etc. They cost between $ 6 to 12 shipped vs the original for about $ 45. So the choice is yours. I have been using 3rd Party + Original Pentax Batteries on my K20D and K-5, and have found absolutely no difference. Being an electronic buff, a DIY and a master mechanic, I keep a track of the voltage when fully charged, half charged and discharged of 3rd Party as well as the Originals. All my (9) batteries are going strong even after over (3) years. You are just plain unlucky (Bad Karma) if one has exploded on you!!! So can bad Original Pentax batteries - after all Pentax and the Canikons don't manufacture batteries.

Re: Third Party Batteries
Thanks, everyone for the feedback. I thought about ordering via Amazon as I still have some credit there from a gift card last Christmas. I got as far as checkout only to be told we can't ship this product to your default destination. Bummer. Oh, well - there are other alternatives. Cheers Brian ++ Brian Walters Western Sydney Australia http://lyons-ryan.org/southernlight/ Quoting Igor Roshchin s...@komkon.org: I bought the one by Zekos which is labeled to have much higher capacity (2800 mAh) than the OEM from Pentax: http://www.buydig.com/shop/product.aspx?sku=ZELI90 http://www.amazon.com/Zeikos-ZE-LI90-Lithium-Battery-Replaces/dp/B002ZRPWPY/ It had been sold only by Buydig and Amazon, and doesn't seem to be available anymore. All other 3rd-party batteries that I've seen do not have this high capacity. To be fair, - I haven't yet tried to measure/compare its true capacity. I haven't had any problem over 1 year period since I bought it. (I paid ~$17 for it.) The battery that Buydig sells now is rated at 2100 mAh, and costs $14.50: http://www.buydig.com/shop/product.aspx?sku=VDPDLI90 The original Pentax battery is rated at 1860 mAh and costs $40-45.

Re: Third Party Batteries
I can't say anything about third party batteries in the K5/7 but I've been using a flashpoijnt battery in my K20D. It gives about 1/2 - 2/3 the number of shots as the OEM battery at about 1/4 the price. So it makes economic sense.
