Capacity refers to the amount of energy a battery can store, usually measured in amp-hours (Ah). A higher capacity means the battery can power devices for a longer time before needing a recharge. This is essential for RV users who rely on batteries for extended periods without access to shore power.
Lifespan indicates how long a battery can function effectively before its ability to hold a charge diminishes. It is typically measured in charge cycles. A battery with a longer lifespan will provide reliable performance over the years, reducing the frequency and cost of replacements.
The interplay between these two factors can affect overall user experience:

• A battery with high capacity but short lifespan may require frequent replacements, leading to higher long-term costs.
• A battery with moderate capacity and a long lifespan may be more economical, even if it has a lower output at any given time.

Factor	Description	Impact on Performance	Example
Capacity	Amount of energy stored, measured in amp-hours (Ah)	Higher capacity allows for longer usage before recharge	100 Ah battery
Lifespan	Duration a battery can function effectively, measured in charge cycles	Longer lifespan reduces replacement frequency and costs	500 charge cycles
High Capacity, Short Lifespan	High energy storage but frequent replacements needed	Increased long-term costs	200 Ah battery with 200 cycles
Moderate Capacity, Long Lifespan	Balanced energy storage with fewer replacements	More economical over time	100 Ah battery with 600 cycles

Therefore, when selecting a battery for an RV, it is essential to consider both the capacity and lifespan to ensure optimal performance and value.
