I have some 18V alkaline battery packs that read 16V on a multimeter. First question - are these still worth keeping? If so, I was wondering if there was a useful/fun use for them. LED light strip maybe? Anything that would make an interesting home/shed project for a novice, don't mind spending a little money to buy tools and bits. Each pack has 2 x 2-pin connectors to connect in parallel. Battery pack details (as read from the label) 18V / 30Ah / 540Wh. Also have smaller packs 18V / 10Ah / 180Wh. The packs were originally used for running an environmental recording device in the field.

\$\begingroup\$ Excellent advice! But I'll probably need more instruction than that. Any websites I should go to? don't really know what I'm doing but keen to use them for something. \$\endgroup\$– user2175481Sep 8, 2021 at 12:07

\$\begingroup\$ Please edit the question to limit it to a specific problem with enough detail to identify an adequate answer. \$\endgroup\$– Community BotSep 8, 2021 at 14:06

\$\begingroup\$ Make sure to test battery voltage with some kind of load attached. Battery voltage reported without load attached can be very misleading. \$\endgroup\$– MicroservicesOnDDDAug 12, 2022 at 9:37

At an average of 1.33V /cell they still have about <20% SoC or juice left.

You could disassemble one, and use the cells individually to power some "joule thief" kind of contraption.
