Hi all,

I don't think they are rechargeable - Alkaline batteries generally are not - as fa as i know.

I have a similar battery (also ripped from a blinking "road work lamp") and it last a very long time but it's not rechargeable.

Just take a look at your application board. There you can find an ic named 78xx05 or something. This is for voltage regulation. 05 means 5 Volt. But you need some more parts around. Take a look at the data sheet http://www2.produktinfo.conrad.com/datenblaetter/150000-174999/156048-da-01-en-SPANNUNGSREGLER_L7805CV_STM.pdf
