Replacing batteries on sealed lights?

Has anyone successfully replaced the battery on a light that wasn't meant to have its batteries replaced? What light? Has it affected water resistance or performance?

My specific interest is in tail lights, especially those narrow enough to be strapped to a seat stay. I use PDW Danger Zones because they use AAA batteries but I want to add more lighting to my bike. I'm looking at the Blackburn 2'Fer XL (I have the regular 2'Fer and like it) but it's not meant to have the battery replaced. I'm trying to reduce waste.

I'm going to assume that "non-replaceable" implies rechargeable, most likely Li-ion.

If so, it boils down to specific manufacturing details. Some are easier to deal with like soldering leads to the battery vs. using a clip in system.

But others aren't so easy to work past, like a non-standard battery not available commercially, or the light being assembled via ultrasonic welding vs. being made to take apart.

So, maybe you can settle on a wel l made rechargeable battery being as green as you're going to get.

My little Bontrager ION flares are more than 7 years old. They still hold a good charge. I've tossed lights with replaceable batteries in way less time. And have even tossed rechargeable AA and AAA batteries themselves in less time.

So what's been more waste?

Why the obituary subforum and not gadgets and gizmos? Some of the more active people on lights never are seen here.
