This UltraLast rechargeable LiIon battery is an OEM version of Casio's official NP-40 battery for many members of the Exilim family of digital cameras: EX-Z40, EX-Z50, EX-55, EX-Z57, and (I believe) EX-Z750, among others.

The official Casio NP-40 costs over $45 here on Amazon (list $49.99), so this UltraLast clone is a great value. Usually I'm very cautious when it comes to generic rechargeable batteries, since the poor-quality ones can explode if over-charged, but I decided to take a bet on this one since it's sold by Amazon. Plus, it actually has more power (1300 mAh) than the Casio one (1230 mAh).

I received my UL-CNP40 a couple days ago and so far it seems safe and reliable. Charging takes a little over 3 hours just like with the NP-40 that came with my EX-Z55, and over the weekend I shot a few hundred photos and saw no difference in performance between this and the NP-40.

So I think this is a keeper, although, a paranoid that I am, I'll use the Casio NP-40 as my main battery and keep this chareged as a backup. Between these two batteries, I'm confident I can shoot over 500 pictures with LCD and flash on, and probably over 1,000 with LCD off and using the EX-Z55's optical viewfinder.

BTW, if you get this or any other battery as a spare, you should also get the Casio rapid charger BC-30L, available here at Amazon for $44 or so. It's a wall plug-in type and you can charge one battery while using the other. (Otherwise you'll have to charge one battery in camera, take it out, and charge the other battery before you head out on your trip.)

So far, the battery seems to hold its charge and is available when I need it. The only problem is that it fits pretty tight and I've had trouble getting it back out of the camera (I remove the SD memory card to allow a little extra room for grasping it but it's still difficult). For the price, I'm happy.

although this battery did fit into the battery slot in my casio camera it is a very tight fit and therefore very difficult to get out of the coamera. It works but you need nails or other gripping toolto remove from the camera

This was a replacement battery for my Casio Exilim camera. It fits perfectly and works as advertised.

I've had the battery about a month now. It fits fine in the camera and takes the same amount of time to charge as does the original. Looks like a winner to me.

I have 5 of thses batteries for two differenttype sof cameras.

They recharge quicklly and are long use.

If you spend alot of time doing flash photography then you may need a couple extra.

Great little unit for the price.
