Buying Guide
Choosing the right AGM 6-volt battery for your RV involves a few key considerations. Here’s what you need to keep in mind:
- Capacity: Think about how much power you use. Add up the wattage of all your appliances and devices, and estimate how long you’ll be using them each day. This will help you determine the Ah (amp-hour) capacity you need.
- Lifespan: AGM batteries have a limited number of charge cycles. Higher-quality batteries like Lifeline tend to last longer, while budget options may need replacing sooner.
- Size and Weight: RVs have limited space, so measure your battery compartment before buying. Weight also matters, especially for smaller RVs.
- Brand Reputation: Stick with reputable brands that have a proven track record. Read reviews and see what other RVers are saying.
- Budget: AGM batteries can range in price from affordable to premium. Set a budget and find the best battery that fits your needs without overspending.
- Maintenance: One of the best things about AGM batteries is they require minimal maintenance. Check the terminals periodically for corrosion and keep them clean.
