RV Battery Replacement & Upgrade in Hobe Sound, FL
Battery replacement, lithium conversion, bank sizing, terminal cleaning, parasitic draw testing, and charging system optimization.
Your RV batteries power everything when you're off the grid: lights, water pump, slides, control boards, and safety systems. In Florida's heat, batteries degrade faster than in cooler climates. Lead-acid batteries that might last 4 to 5 years up north typically last 2 to 3 years here because high temperatures accelerate sulfation and electrolyte evaporation.

What We Do
We replace dead or failing batteries with the right type and capacity for your RV. We upgrade lead-acid systems to lithium LiFePO4 for longer life, more usable capacity, and faster charging. We test for parasitic draws that drain batteries overnight, clean corroded terminals (a constant issue in coastal Florida), and optimize your charging system to extend battery life.
Signs You Need RV Battery Replacement & Upgrade
Your batteries won't hold a charge overnight. Lights dim when the water pump kicks on. Your battery bank is more than 3 years old (lead-acid in Florida). You see green or white corrosion on the terminals. The converter charges but batteries still read low voltage. You're planning to add solar and want a lithium upgrade.
Pricing
RV Battery Replacement & Upgrade typically costs $150 to $2400 depending on the specific issue and your RV's make and model. We provide an exact quote after diagnosing the problem on site. No work starts without your approval.

RV Battery Replacement & Upgrade FAQ
How much does a lithium battery upgrade cost?
A single 100Ah lithium LiFePO4 battery costs $800 to $1,200 installed. A full bank for off-grid living (200-400Ah) runs $1,600 to $2,400. The upfront cost is higher than lead-acid, but lithium lasts 3 to 5 times longer.
How long do RV batteries last in Florida?
Lead-acid: 2 to 3 years. AGM: 3 to 4 years. Lithium LiFePO4: 8 to 12 years. Florida's heat shortens lead-acid life significantly compared to cooler climates.
What's a parasitic draw?
A small electrical load that drains your batteries even when everything appears to be off. Common culprits include LP detectors, stereo memory circuits, and failing control boards. We use a clamp meter to isolate the circuit causing the draw.
Should I disconnect batteries during storage?
Yes, especially in Florida. Disconnect the negative terminal to prevent parasitic drain. Consider a solar trickle charger to maintain charge during long-term storage.
Can you mix battery types?
We don't recommend mixing lead-acid with lithium, or even mixing old and new batteries of the same type. Mismatched batteries cause the weaker cells to drag down the stronger ones and shorten overall life.
Do I need to upgrade my converter for lithium batteries?
Often yes. Many older converters use a charging profile designed for lead-acid batteries, which can undercharge lithium. We'll check your converter's charging profile and upgrade if needed.
