How to assess battery health in remote site vehicles

[Dustcrest]

With our haul trucks often located far from the shop, it’s crucial to know which batteries are failing before they leave us in a bind underground.
Jumping them can be quite the ordeal. What field tests or portable tools can reliably check battery health in remote areas
without needing to bring a full diagnostic setup each time?

I always have a small handheld load tester and a clamp meter in the service truck. In just two minutes, you can do a quick crank check and figure out which battery is causing the issue before it leaves you stuck underground.

For our tests, we also use a portable conductance tester and a thermal gun. When batteries are bad, they heat up quickly under load, so you can easily identify the weak one without needing to take it back to the shop.

I just toss a carbon pile tester and jump pack in the box. You load it up, watch the voltage drop, and you've got your answer before anyone starts pushing a dead haul truck.

If it cranks slow under load, it’s already telling you the story, meters just confirm it.

A handheld load tester is your best friend out there, it beats discovering a dead battery underground the hard way
