Summary: Olympus BLM-01

Comment: It's a genuine Olympus battery for close to half its list price. I got good prompt service, even with USPS. A good deal! Always keep a spare one charged up!

Summary: Olympus BLM-01 Lithium-ion Rechargeable Battery

Comment: This Olympus BLM-01 Lithium-ion Rechargeable Battery is used with our Olympus E3 digital SLR camera. The battery works very well, charges and holds as promised, and is reasonably priced. For even better results, use with the Olympus battery chamber for double power.

Summary: Works as expected

Comment: This battery is identical to the one shipped with my E-520 and lasts just as long. I have three batteries (two Olympus, one Digipower) and can see no discernible differences in their durability -- all have quite a lot of stamina, 800 photos or more.

Summary: You need this!

Comment: Everybody needs a backup battery, because you will never know when you might run out of power. Buying a genuine Olympus product gives a peace of mind.

Summary: Reliable, long lasting powerhouse

Comment: I take 20,000+ pictures per year, so I go through a lot of batteries. I bought a "longer lasting" knock off as a second battery for my C8080 in 2004. It was slightly higher capacity but failed after <2 years. After that I bought a second Olympus BLM-01, and haven't regretted it. On the C-8080 I consistently got 400+ pictures per charge while using the LCD, and 650+ using the viewfinder only. I now have an E-510, and on my first outing I started with my now 4 year old 40,000+ shot BLM-01 from the C-8080. I took over 1000 photos before needing a battery change, including several sessions where the camera was on for several hours (the e-510 has good power save settings). This is a long lasting, very reliable battery and I'm glad Olympus is still using it.
