Batteries are Bombs! Learn how to replace them with Battery Eliminators and Parallel Battery Adapter Holders.

I mean you’re describing a huge variety of products with that one phrase, and I welcome the question - But the intelligent parts of a smart charger are components that can break or die, particularly if you’re constantly stressing it with being on and checking to add voltage/cycling. One part of the circuit on these dies out and other protections stop working too. Batteries are pretty unstable once that starts happening and then fire from heat or too much voltage becomes pretty easy to happen.

The battery itself is built to have some protections, too, but if you google “battery charger fire” you’ll find hundreds of images and news stories.

Just sayin’ - Use a charger for a battery til it’s charged and unplug. Smart phones and tablets seem to be more robust so I trust them to stay plugged in with their charging cable.

Many of these problems with leaking alkaline and NiCad batteries could be solved by just, you know, taking the batteries out of any device you’re not planning to use in a while. White vinegar or lemon juice can clean up most battery corrosion.

I once lived in a house that 120v AC and 12v DC wired in different areas, all using standard AC outlets. They were clearly marked but mistakes were still made.


What kind of monster would do that?! Surely that can’t be to code.

During the inception of residential eleciticity DC lines would be ‘taped’ to the lead water pipes. Many persons died clutching a basement water pipe that was grounded to DC… industrial correction no doubt by insurance company interests.

Todays remote power source… tomorrow toxic land fill.

Enjoy folks.


Modern American code, hell no. But people don’t always follow the rules. :wink:
