Backup battery swaps used to take me 40 minutes, now about 8
I used to unscrew every panel, yank the old SLA out, and juggle wires while trying not to short the terminals on the metal box. That all stopped after a nasty spark in a crawl space near Toledo that killed the panel board and cost the customer a full replacement. Now I just cut the two leads, tape them off, lift the battery, and wire the new one with quick-connects pre-crimped on both ends. I keep a small pouch with three sizes of crimp connectors and a 10mm ratchet in every truck so I never touch a screwdriver unless the panel is ancient. Anyone else switch to quick disconnects and never look back, or am I the only one who hated that fine-stranded wire mess?
Did you see that thread on the Garage Journal forum about doing this with Wago lever nuts instead of crimps? Guys there swear the fine strand wire holds better and you can pull the battery without cutting anything.
