Product Description

This is a 1050mAh high capacity replacement battery. The higher the mAh rating, the more power a battery can store and the longer it will last per charge. It contains premium Japanese grade A battery cells and is guaranteed to outperform the Casio original battery. This battery is CE certified and built to meet or exceed the OEM specification. It is guaranteed to safely power all cameras that use the Casio NP-20 or NP-20DBA batteries. The lithium ion chemistry of this battery makes it 100% memory free. Unlike Nickel-Cadmium (Ni-Cad) batteries, lithium ion batteries don't have a "memory effect" which shortens their capacity. They can be partially charged and/or discharged without worry of shortened battery life. Are you concerned about protecting the environment? Do you worry about exposing your family to electronics containing hazardous heavy metals (such as lead or mercury)? You can rest easy knowing this battery is manufactured in accordance with the strict RoHS standards, which call for the Restriction of Hazardous Substances in electrical and electronic equipment. Unlike most aftermarket power supplies, our batteries have undergone rigorous cell cycle testing before leaving our factory. If a battery does not pass our benchmark testing for superior performance, it will be eliminated from the production line. This guarantees the best possible quality in all our batteries and virtually eliminates the chance of a product being shipped dead on arrival. This battery includes a 3-year warranty. Because we use premium Japanese cells and the highest quality components, we are confident that the battery will last the duration of the warranty and beyond. However, in the rare case where you experience a problem with the battery within the warranty period, it will be replaced promptly. Battery Specs: 3.7V, 1050mAh, Rechargeable Li-Ion; Compatibility: Exilim EX-M1, M2, M20U, S1, S2, S3, S20U, S100, S500, S600, S770, S880, Z3, Z4U, Z60, Z70, Z75, Z77.

This review is from: 1050mAh NP-20 / NP20 Replacement Battery for Casio Exilim EX-M1, M2, M20U, S3, S20U, S100, S500, S600, S770, S880, Z4U, Z60, Z70, Z75, Z77 - Japanese Cells (Electronics)

I purchased this for my Casio Exilim S880 digital camera.

My original Casio brand NP-20 battery was still working great after 18 months, however I needed a second battery for some lengthy video projects. I was hesitent to purchase a non-name brand battery, since in the past I have had poor results with generic batteries. However for the about 1/2 the cost, I could get a battery with 2x the power. I decided to take the risk.

This battery does perform as advertised. I have not yet ran out of juice while shooting. My estimates rate this battery at approx 2 hours of continuous HQ video film time - confirming that this battery does have 1050mAH of power (compared to the 630 mAH for the Casio brand battery).

Since I've only had this battery for 30 days, I cannot yet determine how this battery will hold it's charge over time. The Casio brand battery I am impressed with. Even after 18 months, I can still shoot HQ video for 45 minutes nonstop. Initially, the max battery life was approx 1 hour.

This battery meets all of my expectations and deserves 5 stars for the value and performance. I recommend it.

-- UPDATE --

I recently had two chances to test this generic battery's capacity in one single video recording. On both video shoots, the battery lasted only 1 hour (highest video resolution, manual WB, anti-shake off, Casio Exilim S880). This is the same performance of a new Casio brand battery.

It appears to me that the 1050mAH power capacity rating is not accurate. My Casio Exilim 630mAH battery also lasted 1 hour at the same camera settings when new.

This new battery holds a "green / full" battery rating for over 45 minutes, then quickly drops to "yellow" and "red / empty".

I would reduce my rating to 3 stars if Amazon.com allowed me.

I use this battery in a Casio Exilim S880. With the original Casio battery, I never worried about charging the battery. It would get charged every couple of weeks when I would download pics. With this battery, I have to constantly be aware of the charge. I bought two of these and and now figure the two together equal one Casio battery.

This Japanese Replacement Battery performs as well or better than the original. At this price, I got 2 and carry a charged spare in the camera case at all times. No more worries about running out of power!!
