UPS and 18650 Lithium ion batteries
UPS and Panasonic Sealed Lead Acid (SLA) batteries
In those were my good old Arduino days (2008~2013) I played with lead batteries, but just for fun, and never used in any completed projects (well, almost all my Arduino and Rpi projects never completed!
This lead battery is only 4AH, seems not efficient when comparing to the much smaller sized 16450 which is 3AH.
