Battery Shoot Out - Pentax Optio W80Mar 22, 2010
By Chicago John
"Rirelguvat vf rinarfprag."
There is an old saying, "You get what you pay for."
There is another old saying, "Some things are too good to be true."
Here is a new saying: Sometimes old sayings should be empirically verified.
=============== BATTERY SHOOT OUT: =================
Contenders: At $29 on Amazon, the stock Optio W80 battery, Pentax D-LI78 680 mAh
Hoys Corp, Made in China 3009-08-25-BCB
The $6.69 Maximal Power (for Pentax DL-178/ Nikon ENEL-11 880 mAh,
cells made in Japan, assembled in China
Preconditioning: Both batteries: Brand new. Fully drained and recharged twice using the
Pentax W80 battery charger.
Testing temperature: The low cost one went first: 32 - 34 degrees F. The "champ" had a slight
advantage at 36 - 40 degrees F.
Camera: Pentax W80 THE best trail-worthy camera for-the-buck available. See my Amazon review.
Mode: Interval Shoot. Every ten seconds for up to 1000 shots maximum
Resolution: 12 Mega Pixels at best *** Quality, daylight without flash
Subject: Bird Feeders after snow fall in Chicagoland
Medium: 8 GB card newly formatted
Result: 956 pictures Champion Pentax D-LI78 battery $49.95 list, Amazon price $29
888 pictures Low-cost Contender at $6.69 (with free shipping on orders over $25)
Interpretation:
The results of this experiment apply to a sample of only ONE from each population. Results may vary for each individual. For example, what if "rejects" from the Pentax production line were labeled "Maximal Power"? Maybe I just happened to get one that performed very closely to the gold standard.
But based upon my results, I have purchase two more and I will test them using the same protocol and report the results attached to this review.
Postscript: The Pentax Optio W80 together with a good "noiseware" program and these low cost batteries is a rocking combo for some "off-the-road" work where you have to leave your DSLR at home, or in the trunk. (now i get to go through 2000 high res bird feeder photos looking for the one or two I know have to be prize winners... even a blind squirrel has to have a nut in 2000 pictures, right? :-)

By smart shopper
I bought this extra battery for my camera and it has worked very well. It has been charged a number if times and seems to hold the charge well for what I do with the camera.

Shipped very quickly and was exactly as stated in the description. We needed this unique item for our office camera's (which we depend deeply on) and I was able to find them quickly on Amazon. Received them in 5 days!!! Thanks
Lives up to its advertised descriptionNov 17, 2011
By Jan Alter
I bought this battery for my daughter last summer as a secondary battery for her Pentax. She was fortunate enough to be taking an outback course with nine other youths in the mountains in Washington state for a month. The battery lasted as long as the original. However, upon return she realized she should have gotten still a second spare. Although there are much cheaper batteries experience reminds me that one usually gets what they pay for... as long as one has done their homework.
