Sennheiser BA151 Rechargeable NiMH Battery Review

Sennheiser BA151 Rechargeable NiMH Battery

I love my Sennheiser wireless headphones -- except for the battery. This battery rarely lasts more than 2 hours. That's why I have a charging unit that charges two batteries. Also to keep in mind -- these batteries wear out fast. There's only so often you can recharge these things before they die completely. If I'd known how many of these $20 batteries I'd be going though, I would probably have picked a different brand of wireless headset.

Ultralast UL-BP38 Replacement Rechargeable Battery for Uniden GMRS/FRS Review

My battery died prematurely, probably due to the fact that the radio never leaves its base. In a house setting it's vitally important for a two-way radio to operate while in its charging base. The problem is that the battery rarely gets a chance to exercise and will probably die due to non-use.
This generic battery module is fully compatible with the radio and costs less than 50% of the original manufacturer's unit.
I tried to use regular AA-size NiMH battery in the radio--they work to operate the radio but they will not recharge inside the radio for reasons I cannot identify. This was a big problem. It was important to get a custom-made battery for that radio that matches the radio's charging circuit. Even my regular source of custom-made battery modules did not have a properly fitting battery module for my radios.
I'm not sure what the problem was with regular NiMH AA-sized batteries, but this battery solves it at the same price as four NiMH AA batteries and way cheaper than the batteries the original manufacturer offers, and even cheaper than the custom-made battery vendor.
**EDIT** This battery is going strong in late 2010. I believe the original radio was discounted due to battery failures. I still saved quite a bit even with this new battery.
