Pentax battery - too good to be true??

Looking for a D-LI 109 battery for my K-70, I came across this apparently genuine Pentax one for 17.50 from China on Ebay.

Is this "too good to be true", or is it a genuine bargain? I want a genuine Pentax product as I'm finding compatibles don't seem so good.

Any thoughts, guys?

I have seen these for the K5 and K3. It'll either be a knock off or not... is it worth the chance??? Tho they're more than likely a knock off.

To be fair everything is madev over there!!!

I have Maximafoto ones and theyre adequate for a bit less cash.

~70 quid for a battery is outrageous...

First look at the mAH 1050 the Pentax are 1860 mAH I have others which are 2800 and DSTE and all work fine. OK buying compatibles if you know they are but these ones sound like a complete rip off. I'd steer clear.
CHEERS Vic.

Indeed they are. And one that I bought many years ago is still going strong while a much more recent one has packed up. Which goes to show (IMHO) that while 70 is undoubtedly far too much for a battery. beyond a certain point the less you pay the more likely you are to get a dud. The game is to find the point at which price / reliability is lowest. I'm still looking...

I've got seven of them on the go - all sorts of makes. They are strictly rotated between two cameras and have been going for years. I've just withdrawn a Maximafoto that no longer holds its charge after about 7 years use. I bought two new ones last year (un branded) that are still in their boxes.

HI
I have had good results with Kastar chargers and batteries. I like the lay-flat two-port charger and the batteries seem well-made and last without swelling. I have them for my Pentax Q, K S2, KF. Also have them for my Panasonic Zs70K.

There's no way that's the genuine article.

I bought third party batteries for my K-3 and they started out holding around 75% of the charge of a genuine battery but after a year or so one of the two held virtually no charge at all and the other maybe 50% of the genuine one.

Genuine batteries for all manufacturers are a ridiculous price but faced with alternatives as bad as they are I hand over the cash and live worry-free.

1050mAh is correct for this battery, but it is most unlikely to be genuine. I too have bought, and use, 3rd party batteries that are sold with no pretence about what they are - batteries that in form factor are equivalent to an OEM product, but aren't passed off as genuine or original.

I'd avoid these so called 'Pentax' ones.

Thanks for all your replies, I'll take the advice on-board.

One thing to be wary of with 3rd party batteries = a "tendancy" for some to swell after a year or two. If you are not observant, they can swell enough to be difficult to slide into the battery compartment - and then even more difficult (if not impossible!) to later remove!

That's a far more realistic price.

I bought a couple of 3rd party (DSTE as it turned out) batteries when I bought my K3 in 2017. I actually only wanted a USB charger, but several chargers on Amazon were available at a price that meant that the extra batteries were almost free!
So it wasn't a conscious decision to buy DSTE -more of a "what the heck..."

I now rotate them, and I honestly see no significant difference between the 2 x DSTE and the original Pentax one.

I do realise that a sample size of 2 is statistically not really significant, but the 4 x 3rd party (dot.photo) ones for my Lumix and 3 DSTE's for my Fuji have performed sufficiently well over the years that I'll happily buy (certain) off-brand ones in the future.

And I could live with binning the odd one or two if they don't last, given that I can get 6 or 7 for the price of an OEM one

I've bought DSTE clones of both D-Li109 & D-Li90 batteries, and they've generally had decent capacities and worked quite well - unlike some other clones where short lives &/or swelling proved problematic.
