I have a Pentax Optio A30, which is an older digital camera and needed new batteries for it as the ones that came with it do not hold their charge like they used to, so I was delighted to find these batteries at such a reasonable price. The old ones were 800 mAh and these new ones are 1500 mAh so they should hold the charge better.....I would buy these again!!!!

Works in my 21 year old Panasonic camera and recharges quickly.

Just installed battery today, so no long term exposure as yet, however this test was good to tell me if it would fill the bill. Wastransferring lots of files off the SD card to HD, and the camera was on for about 3 hr. straight being used constantly for this exchange. The battery worked fine, looking forward to see the working life span of this battery against the original Pentax battery, however this one has double the mAh output of the original, so the unit carries good signal strength.

I use these for my work camera, where I typically take more than six dozen pictures daily. I bought two of these so I can maintain constant operation while one is on the charger. (Both my original OEM batteries began dying at about the same time.) I've had the Wasabi batteries for a couple months and, so far, they are meeting my expectations. I don't foresee any issues. And no "issues" is a good thing.

The battery is Dead. Charged it the day it arrived, put it in the camera and it just didn't work. Heck the old 10 year old battery, charged and worked for at least a day. I have to figure out how to return this thing.

Put it in camera, charged it and it worked like new. Haven't used it enough to know how long it will last on a charge but so far so good.

Order arrived promptly however it was filled incorrectly. I ordered 4 D-L18 batteries and the order arrived with three D-L18 batteries and one labeled BTR-FV50-JWP, which is a completely different size and type of battery. In all fairness, the packaging was mis labeled with the D-L18 bar code. There is a 2 to 1 difference in thickness, so obviously different contents.

I have never before ever ordered anything from Amazon. I ordered two of these because the original Pentax battery finally gave up after 8 years and no one in the NH area had any in stock for a decent price. These were very affordable and arrived very quickly. They fit the camera perfectly. I have no complaints whatsoever.
