Recommendations for a Third party K-5 battery

Quoting "P.J. Alling" : I though the K20D battery took a long time to fully charge. Started to do some research and then decided ask the people who know. I bought some third party batteries for my K-5 on eBay (they're branded 'DSTE'). I haven't noticed any difference in performance or charging time in comparison with the OEM Pentax battery - not that I've done any specific tests. -- Cheers Brian ++ Brian Walters Western Sydney Australia http://lyons-ryan.org/southernlight/ -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.

I have a Meike battery grip for my K-7 (it is the same model for the K-5, as they share the same camera body). It works well and it is well built (for a knockoff). The only disadvantage is that it is not weather sealed as the original Pentax. It also comes with an adpater for 6 AA batteries, besides of the adapter for DL-90 lithium battery. It was quite cheap, about 35 euros.

Re: Recommendations for a Third party K-5 battery
I don't think that saving few pennies on the battery and then accidentally having to deal with the issues that may arise is worth it. I had some 3rd party batteries for my K10D, one was really weak, another was satisfactory. But since I upgraded to K-7 I resolved to use OEM batteries only. No regrets here. The same by the way applies to the battery grip. The 3rd party grip turned out to be not very well made as far as electronics went. So again I have OEM grip and it is performing flawlessly...

I'm sorry but the answer I gave in my previous message was all wrong, I understood you wanted to know about third party battery grips, nor 3rd party batteries. I have to learn to read again. Besides the original battery DL-90 which came with the K-7, I bought an Energizer branded compatible battery. It works as well as the original, so I can recommend it.

Re: Recommendations for a Third party K-5 battery
That is kind of why I asked advice. I bought a Flashpoint battery with better specifications that the OEM battery for the K20D. It's reliable, charges quickly, and in keeping with that seems to hold about 1/2 the power of the OEM battery. It's good in a pinch, but... I'm looking for a sense of the list, if a particular brand gets decent reviews. I'll look into buying it.

Re: Recommendations for a Third party K-5 battery
I have a Pearstone charger for D-Li90’s. The same basic charger is sold with various slide-in clip-in battery cradles for various battery styles. The unit plugs directly into the wall with fold-out prongs - no messy cords to cope with. I’ve used this for a least a couple of years with no issues. Charging speed compared to OEM? I have no idea. I put the battery in, eventually it is ready, I take it out and repeat as needed with additional batteries.But I don’t think it is appreciably slower than the Pentax charger. Do the D-Li90’s get as completely charged? Over-charged? Do they hold the charge as long? Again, I have no idea. That is why I carry spare batteries so I needn’t worry about such details. My spares are mostly OEM with 1-2 3rd party purchased via B&H IIRC. Never any issues. The only non-Pentax that I can lay my hands on at the moment is labeled Watson, 7.4v, 1800mAh. stan On Mar 27, 2014, at 6:16 PM, John wrote: > On 3/27/2014 1:27 AM, Brian Walters wrote: >> Quoting "P.J.

Re: Recommendations for a Third party K-5 battery
For the D-Li50s that powered the K10D/K20D I have 5 batteries & 3 chargers. I have the two Pentax chargers that came with the cameras and an after-market charger I bought that has the folding prongs for 110VAC and plug-in adapter for the 12VDC in the car. The only non-Pentax battery I have is a Konica Minolta NP-400 1500mAh. I've never noticed it being any different than the Pentax branded batteries. The Pentax batteries came with the K10D, the K20D, the K20D battery grip and Wolf Camera when it was going out of business. I like being able to keep the "spare" battery on the charger even in the car. That way the length of time it takes to charge becomes moot. I'd like to be able to do the same for the D-Li90s. The cost of the Pentax branded batteries doesn't bother me that much, given that I've not yet seen any of the aftermarket batteries with a higher rated capacity.

Re: Recommendations for a Third party K-5 battery
I bought a battery through Amazon that claims 2800 mAH and the box ("High Voltage Technologies") says 2900 mAH. I haven't managed to run it down yet, but I've only had a couple of 4-5 hours shoots so far. Cost under $20 Canadian, free shipping. The OEM battery is easily four times that price here. http://www.amazon.ca/gp/product/B004F0EX5O On Thu, Mar 27, 2014 at 7:51 PM, John wrote: > For the D-Li50s that powered the K10D/K20D I have 5 batteries & 3 > chargers.
