RV Batteries

RV batteries power your lights, water pump, furnace fan, fridge controls, and electronics while you’re camping. Choosing the right battery makes the difference between a relaxing trip and running out of power halfway through the night.

At Century Batteries, we help you choose the right RV battery based on how you actually camp. Weekend trips, full hookups, dry camping, and solar setups all require different battery types and capacities. We carry high-quality deep cycle AGM, flooded, lead carbon, lithium batteries and more designed for long run time, durability, and reliable performance. We also provide free battery testing so you know the condition of your current battery before replacing it.

Whether you’re preparing for camping season, upgrading your system, or troubleshooting power issues, visit our Abbotsford, Chilliwack, or Port Coquitlam locations and we’ll help match the correct battery setup for your RV.

RV Battery FAQ

What is the difference between a starting battery and an RV battery?
A starting battery delivers a quick burst of power to start an engine, while an RV battery is a deep-cycle battery designed to slowly provide steady power over long periods. Using a starting battery in place of a deep-cycle battery will result in very short lifespan.

How long should an RV battery last?
Most RV deep-cycle batteries last four to seven years or more depending on quality level or how deeply they are discharged and how well they are maintained. Regularly draining the battery completely will shorten its life significantly.

AGM vs Lithium vs flooded deep cycle — which should I choose?
AGM batteries are sealed, maintenance-free, charge faster, and perform better for intermittent use. Flooded batteries cost less but require maintenance and ventilation. Lithium has full discharge capability, longer life, and light weight but must be compatible with charging systems and specific usage. The best choice depends charging and usage compatibility, how often you camp, and how much maintenance you want to do.

Why does my RV battery die so quickly while camping?
Common causes include high power appliances, furnace use during cold nights, aging batteries, or insufficient charging from short drives. Capacity sizing matters — sometimes the battery is simply too small for your usage.

Can I add more batteries to increase run time?
Yes. Adding batteries in parallel increases capacity and allows longer off-grid use. We can help you choose compatible batteries and proper wiring configuration.

Do I need a charger or maintainer during storage?
Yes. RV batteries slowly discharge while parked. Keeping them on a maintenance charger dramatically extends lifespan and prevents spring startup problems.

Can solar panels charge my RV battery?
Yes. Solar works well for maintaining batteries and extending camping time. Proper battery selection and charging setup are important for best performance.

Why did my battery fail after winter storage?
If a battery sits discharged for months, sulphation forms inside and permanently reduces capacity. Many RV batteries fail in spring because they were stored without being kept charged.

Do you test RV batteries?
Yes. We can test the battery and help determine whether replacement is needed or if the charging system needs attention.

When should I replace my RV battery?
If your battery no longer holds charge overnight, struggles to run normal loads, or is nearing the end of its typical lifespan, replacement is recommended before your next trip to avoid problems while camping.
