cant tell from pics...but i think you need new batts?...one of the wires seems alittle burnt!
at least your truck is not a TOTAL loss!

You definitely need a new fire extinguisher, those first alert/safety firsts are one shot deals, can't recharge them. If you buy another of the same cheapo extinguishers, open the box and check the gauge before buying, there's about a 25-40% chance it's dead new in the box. The ones that say "commercial" on them are metal instead of plastic and are more reliable.

Sorry about your battery and the rant. I work with fire extinguishers and can't stand those cheap, unreliable, plastic pieces of junk. I'm glad it worked when you needed it, but I'd consider myself lucky it did.

My sister's a firefighter and an emt. Already got a new one and its the real deal :yes:
