What buyers say about AstroLight OEM VL2020 ML2020 - Rechargeable Battery
I soldered the new battery in and tried to push it against the circuit board, but it wasn't flush enough to allow the two plastic shells to mate.
The 4 cell pack is fabricated and works fine.
It was well made.
It worked as expected.
It worked well, but it required some tweaking and the battery died a few months later.
