Reliable power source


from Monterey, CA  -  Photo Enthusiast

This battery readily takes a charge and holds it for a long time. It provides impressive performance in my 1050 SW camera. I keep two on hand so I always have a charged back-up available.


Very good and fast to my door


from Wetumpka, Alabama  -  Casual Photographer

Over all they have been very good.

Questions about this item:

Shopper  Why Did You Choose This?
JOSEPH H  To have an extra battery for my Olympus Stylus camera.
LLOYD L  The label on the battery I wish to replace is identical with the illustrated one except for the bottom number which reads 71240BAM compared to the illustrated 80121BAJ. Does this make any difference?
MOACIR A. A  If both batteries have the same size, reference (as in S/N or Product number), polarity, voltage and all the other "must haves" there are no differences.
Shopper  How many years guarantee?
MARK A  I could not find warranty info on Olympus' website, but from personal experience, I bought the 790 SW camera in 2007 and the battery lasted appx. 4years retaining full charge, and then seemed to fade, so I purchased a new one, and the original holds enough charge to work great as a backup.
