Testing, replacement & charging system diagnosis.
RV Battery Service
Battery testing, replacement, charging system diagnosis — 12V, AGM, lithium, and house battery banks.
What's Involved
Your house batteries are the heart of your RV's off-grid system — they run the lights, fridge control board, water pump, and slides. When they fail, everything stops working.
I load-test, replace, and service RV battery banks on-site across Northern Nevada, covering lead-acid, AGM, and lithium setups. I also check the converter and solar charge controller to make sure your new batteries actually get charged correctly.
If you're upgrading to lithium, I'll help you size the bank and confirm your charging system is compatible before you spend a dime.

Battery Service FAQs
Straight answers to the questions RV owners ask before picking up the phone.
If your house batteries won't hold a charge overnight, read low on a meter, or bulge and smell, they're likely done. I load-test them on-site to confirm whether it's the battery or the charging system causing the problem.
Testing and terminal service runs around $100-$150, while a full replacement depends on the battery type — lead-acid is cheaper, lithium runs higher. I'll quote the battery and install together so there are no surprises.
Yes, I swap and test batteries right at your rig, whether it's a single 12V or a full house bank. I also check the converter and solar charge controller to make sure the new batteries actually get charged.
A straightforward single-battery swap takes about 30 to 45 minutes. A full house bank replacement with wiring cleanup can take a couple of hours, depending on access.
