news My wife's Lezyne Deca 1500XXL stopped taking a charge, at all. Taking
it apart, I saw that the batteries were made in July 2015. Not too
good for it to stop working that soon. These lights don't have
user-replaceable batteries, but by removing two screws I was able to
open it, and the battery pack does have a connector on it so at least
they didn't solder it directly to the printed circuit board.

It's a 2 cell 18650 pack with the batteries in parallel, and a
protection circuit board shared between the two cells. The cells are
allegedly 2800mAH, for a total of 5600mAH. The closest I could find
on-line was a 2x2600mAH parallel pack
https://www.amazon.com/dp/product/B003SH4BV6.

I moved the connector from the old pack to the new pack, plugged it
in, and closed it up. Seems to work fine now.

My favourite is recycle bin rescues - with a £0 price tag; life
expectancy isn't something to get traumatised about.

Most laptop packs are 2 or 3P-3S, you can split them up as series or
parallel pairs A/R.


In many areas they won't let you dive into recycling bins. You'd
almost have to lie in wait, dart out and yell "Yo, don't hand over
that laptop just yet!". Otherwise when it's in there it's in there and
not coming back out.

Most don't take any notice - one that said no has the bin next to
customer service desk, reconnaissance on the way in - anything interest
and i make use of the seating and wait for the clerk to nip out.


In the country you live in maybe. In the US there may be a nasty
surprise waiting when trying to leave the store with the treasure, later
followed by a police cruiser for a ride into town but not to the
destination you intended.
