About the service
A house battery is the heart of autonomy for any RV or camper. When it starts to fail — charges slowly, sags under load, or has simply reached the end of its service life — the entire onboard electrical system suffers. I offer a mobile service for battery bank replacement and modernization: I'll come to your parking spot, garage, or campground directly with all necessary equipment to replace worn-out batteries and restore your power system to order.
We start with a short consultation about how you use your RV: weekend trips, full-time living, autonomous camping without shore power, or seasonal storage. Based on this, I help you choose between traditional deep-cycle batteries (flooded, AGM, or gel) and switching to lithium (LiFePO4). Lithium batteries cost more, but provide roughly twice the usable capacity, charge faster, last much longer in terms of cycles, and are noticeably lighter in weight — a reasonable choice for those who often park autonomously. Deep-cycle batteries remain a good budget option for occasional use.
Capacity calculation is not done by eye: I calculate your actual daily consumption based on your appliances (refrigerator, lighting, pump, fans, electronics) and select a battery bank for your actual usage pattern with a reserve for cloudy days and off-season.
The work includes removing the old bank with safe disconnect, inspecting and replacing worn cables, terminals, fuses, and connectors if necessary, installing and securely mounting new batteries to code, and tightening each connection with the correct torque — loose or corroded terminals are one of the most common causes of electrical problems on the road. If you want to add or update a charge monitor with a shunt, I install and calibrate it so you get accurate state-of-charge data on the panel or in an app on your phone, rather than guessing by the voltmeter needle.
Old batteries are taken by me for proper disposal in accordance with local regulations — you won't have to dispose of used batteries yourself. Most work is completed in a single visit, usually within a few hours, and before I leave I test the entire system under load, including charging from the generator, shore power, and solar panels if you have them. Typical replacements can often be scheduled within a few days of contacting me, and upon completion you receive a written report of the work performed and parts installed.
