Batteries & Electrical Service
Batteries do not fail on a warm afternoon in the yard. They fail at 4am in a cold lot with a load on. A set here is under an hour, tested, with the charging system checked so you are not back next month.
Battery sets, installed
- 4× Alliance 925CCA — $599 installed
- 4× Interstate 1000CCA — $699 installed
- Load test on the old set so you know what actually failed
- Charging-system and alternator output check
- Terminals, cables and hold-downs cleaned or replaced
- Old batteries taken and recycled
Both prices are complete — batteries, install and disposal. Under an hour in most cases.
When it is not the batteries
Half the "bad battery" calls are something else: an alternator not charging, a corroded ground, a parasitic draw pulling the set flat overnight, or cables that look fine and are not. Replacing batteries without finding a draw just buys you a new set to kill.
Electrical diagnostics bill at $185/hr — the higher rate is because that work is slow, careful tracing, and it is the only way to fix a fault that comes and goes.
Electrical work we do
- Alternators, starters and charging faults
- Parasitic draw testing
- Wiring, harnesses, grounds and connectors
- Lighting front to back, including trailer 7-way faults
- Sensors, dash warnings and intermittent electrical gremlins

Questions we get asked
How much is a set of truck batteries?
$599 installed for four Alliance 925CCA, or $699 installed for four Interstate. That is the complete price including install and taking the old ones.
How long does it take?
Usually under an hour, including the load test and charging-system check.
My truck keeps going dead overnight. Is that the batteries?
Maybe not. That pattern usually means a parasitic draw or a charging fault. We test for it at $185 an hour rather than sell you a set that will die the same way.
Can you replace batteries on the road?
Yes, battery swaps are one of the most common roadside calls we run on the I-78 corridor.
