Digital Cameras Photo Reviews of Olympus B-50SU 4 AA NiMH Batteries and Charger

Customer Review: Compact and works well
Summary: 4 Stars

Most of the negative comments I've seen here are due to the fact many people don't understand the qualities of NiMH batteries. These batteries work well in devices that draw a lot of power, but don't work well in all devices. They lose about one percent of their charge daily, so I wouldn't use them in a flashlight unless you plan on recharging them at least once a month whether you use them or not.

NiMH batteries are only 1.2 volts, but that's not a problem in most devices since they hold that 1.2 voltage till they die. An alkaline battery drops slowly from 1.5 volts, and continues to drop slowly till it dies. Problem is, while a NiMH battery can hold a steady 1.2 volts for a long time, it drops in voltage very quickly when it does die. That means if your device has a low battery indicator, it may give you little warning. However, most digital cameras are setup to use NiMH batteries, and their battery indicator is adjusted for this.

Also, a NiMH battery must be recycled a few times before it works at full capacity. I put a brand new charged battery in an MP3 player and it ran for less than 2 hours. On the second charge it ran for over 7 hours.

So, why not five stars? There are better batteries and chargers on the market. The newer AA batteries are rated at 2000 mAh, and there are faster, better, "smarter" chargers on the market (MAHA, Rayovac, etc.)that can charge both AA and AAA batteries. Still, I've had good luck with this compact charger and the batteries, and recommend it. I also know for a fact the school has abused the heck out of both the charger and batteries and they are still working fine.

By the way, make sure and get a second set of batteries for your camera. When you come across Elvis, the Loch Ness Monster and Bigfoot all having a picnic, I guarantee you the batteries in your camera will be dead.
