"My battery keeps dying" is the most common thing people tell us, and the battery is often not the root cause. Testing tells us what is really going on.
What we test
- Each battery in the bank, for state of charge and condition under load. One weak battery can drag down a whole bank.
- The converter or inverter-charger. Is it putting out charging voltage when you are plugged in? Is it set for the right battery type?
- Solar charging, if you have it. Panel output, controller settings and connections.
- Alternator charging on motorhomes, for both the chassis battery and the house bank, including the isolator, solenoid or DC-to-DC charger.
- Parasitic draws. Things that pull power when everything seems off: CO and propane detectors, stereo memory, control boards, and sometimes a short. See why your RV battery keeps dying.
- The battery disconnect, fuses, breakers and grounds.
What you get
A plain explanation of what we found and what we recommend. Sometimes that is new batteries. Sometimes it is a fuse, a loose ground, a setting change, or a habit, like leaving the disconnect on in storage.
When to get a test
When the batteries won't last overnight anymore. Before a long trip. When you buy a used RV. After an RV sat in storage all summer. Before hurricane season, if you rely on the RV as a backup.
Questions we get about this
Can I test it myself?
You can check voltage with a meter, and that helps. But voltage alone doesn't show capacity. A load test or conductance test shows much more. Reading battery voltage.
Do you charge for testing if I end up buying batteries?
We explain how testing is billed when we quote the visit.
