    Watson BLN-1 reviews

    BLN-1 Lithium-Ion Battery Pack (7.2V, 1150mAh) is rated 4.6 out of 5 by 69.
    Rated 5 out of 5 by from Works great Finally figured out how to check battery life without firing camera hundreds of times... put on video and let it run so I could compare to other batteries I have. Few weeks ago bought 2 Wasabi batteries that are rated highly, the Watsons run about 15% longer. Original Olympus batteries are few years old and charged and dis-charged hundreds of times and are relatively weak at this point. The Watsons fit properly and are priced right.

    Rated 5 out of 5 by from Excellent battery at a decent price! Working perfectly after 1+ year. I see no difference in performance between this battery and the genuine Olympus battery. But here's a tip: This battery seemed to fail on me at just over 1 year of light use. The contacts looked perfectly clean, so I hadn't thought to clean them. Finally I decided to clean them anyway, and the battery started working perfectly after that. So if you develop a problem with this battery giving you an error when attempting to charge it, do be sure to try cleaning the contacts.

    Rated 3 out of 5 by from Hard to remove from camera. The battery held a charge just fine, but was extremely hard to remove from my OM-D E-M5 Mark ii. Perhaps part of the problem is with the camera, but the two sections of the battery's plastic shell are slightly misaligned at one end, and consequently catch on the outer edges of the camera's battery compartment. The fit and finish do not measure up to that of the original Olympus battery. I plan to return this battery and buy another Olympus battery.

    Rated 3 out of 5 by from Difficult to Remove This battery is affordable, however it's difficult to remove. The tiny line gap between the two sections of text on the battery has a little bump. Therefore it gets caught on the small battery hinge on the Olympus OM-D EM5 Mark II. You have to pull the battery quickly to pass the bump. I'm really fearful that this will damage the camera. Also, this battery needs to be charged the day before or on the same day you're using it. I had it pre-charged more than a week, and when I used it, the charge didn't hold so it lasted about 10 minutes.

    Rated 5 out of 5 by from As good as OEM I purchased a battery when I got a HLD_6 battery holder for my OLY M-5. I will admit that I had previous experience with Watson batteries. I have a Oly Stylus 1, which uses a different size battery. They worked great! I used the Stylus 1 camera on an African safari. I had 2 Watson's and a oem Oly battery. I never ran out of battery power. I will admit that I used a Hahanel battery charger I bought it in Europe many years ago I at that time used a Canon camera. The Oly OEM charger is to slow. Charging 4 batteries after a day takes too long. The Hahnel will charge USB, AA, AAA and 7-8 volt camera batteries not at the same time. This is the best travel charger I have used.

    Rated 5 out of 5 by from Best non OEM battery I've owned I have never had good luck with aftermarket batteries and have always purchased spares from the OEM. Decided to try this one since the OEM was out of stock and I needed something for an upcoming trip with my new E-5 II. Wow! Holds a charge at least as well, maybe better, as the OEM battery and you can use the Olympus charger. No regrets on the purchase, very satisfied with the performance. I did both stills and video and it powered the camera for an entire day of shooting with power left over at the end. Excellent!

    Rated 5 out of 5 by from Works as good as original I bought this as my secondary battery for Olympus OM-ED-M1 camera. I have used it couple of times and I have not found any performance issues compared to the original battery. It fits exactly as the original in the charger as well as in the camera. Charging time is also more or less the same.

    Rated 5 out of 5 by from As good as the brand name I have already been using Watson batteries with other cameras with great success. I'm a professional photographer working full time. I trust this product and it is worth the savings over the original batteries. Highly recommended.
