Spare battery for K10 - advice please

Morning All
As a proud new owner of a K10D I wonder if anyone can offer any comments on extra batteries, i.e. if pattern batteries from China are worthwhile or do they give up the ghost after a short while?
I have just been looking on ebay, best offers I have seen so far from sellers with decent feedback are:

1x1750mAh £6.78 inc

2x1800mAh £11.58 inc

What do you think?

I have 3 extra batteries, none of them are original Pentax.
I have had no problem with them at all, I must admit I don't think they hold the charge as long as the Pentax battery but then you can buy 5 or 6 for the same price.

I also have three non Pentax batteries (NP-400 equivalent)and have had no problems.

Try 7 Day Shop (no VAT for low cost items as they are in the Channel Islands).

personally I would'nt get a battery from E-bay. I have heard of too many horror stories about fake batteries.

If you want a good battery that is half the price of the Pentax, get the Hahnel one. only £20 from WEX, I have one and it is a good as the Pentax one.

i have two of these from amazon work a like a dream £13 delivered for 2

just looked at hyrams link, and there the same but 1500mah instead of the 1300mha on amazon and a couple quid cheaper than amazon, if you can wait buy the 1500mah.
but i can get over 500 pics with my 1300mah.

I have one of these 1750mAh versions

First one I received was Duff but was replaced no trouble and has worked fine since.

p.s. looked on 7 day shop yesterday none of this type in stock

£20 each and there are good.

Like Offertonhatter I bought a Hahnel one for around £20. I've noticed no difference in performance between this and the genuine Pentax but I quite liked the reassurance of having "branded" battery (even if the brand isn't Pentax). I'd used Hahnel products for years and always found them to be of the highest quality.

I've got a no-name one 1500 mAh for EUR 15.50 incl. p+p.
No problems with it so far and I couldn't say that I noticed a difference to the original Pentax one.

Prieni

I bought 2 off these and they are fine

I have 2 pentax and 1 no name 1750mAH type. I personally find the pentax hold there charge longer,but unless your in a remote area for days a no name one is a good backup.

7DayShop is THE place to buy from if not buying a genuine Pentax battery. I bought three about a year ago and they've been working well.

£5.49 postage included.
