Battery Load Test - Simple and Easy

Load testing is the only wait to test an AGM or sealed lead acid battery. A cheap load tester will do the trick. Use on any AGM or flooded lead acid battery.

Hi Marion. I've got one of those on my test bench too. I also use those newer devices that test the battery's internal resistance and CCA capacity. I test my batteris once evey 6 or so months. I sure have a lot of batteries, 4 in the boat, 2 in the 3500, 1 in the dump trailer, utility trailer, tractor, RTV, lawn mower, wife's car, lawn vacuum, my 1500, and finally my ham station's power system. I want to do the best I can to avoid one of those "oh no" events, particularlly in the boat. Best to you and your bride.

Marion: just so happens I had to replace my OEM batteries today on my 2017 ram with the 6.7 L —> $500!
Only place in town that had batteries in stock was O’Reilly’s went with their AGM as well. My question is did you ever hook your truck up to a trickle charger when it was not being drove for a few days? I work shift work where I’m off at some .7 days straight And I’ve always used a trickle charger to keep my OEM batteries at least fully charged or close. Do you recommend that with these AGM batteries?
I’ve read where it’s best to do this with this type of battery at least try to keep it fully charged as possible at all times.

Great explanation for the battery load test.

I've got the same Harbor Freight load tester, only a little newer. Seems to work great.

I bought one of these load testers about a month ago to test out my batteries (both batteries where ruled dead as the truck sits more often than not, luckily they were still under warranty). I find these trucks like/require strong batteries for them to be happy. The slightest hint of a weak battery/s and they start throwing codes.

Marion, did your truck throw a P2609 code? It's a intake air heater system performance code. My truck throws the code when the truck is cold. Outside Temps are usually below 30°f. The truck starts sometimes the truck run a little rough. My guess is the 6 year old battery's don't have enough amps to properly run the grid heater. Hope this issue goes away with new battery's.

I was using mine (same thing Harbor Freight) and a damn bolt fell off of it and went right down into my engine!
