RV / Caravan Battery Degradation Forecast
Year-by-year capacity fade and usable kWh forecast for a rv / caravan battery, to your end-of-life threshold.
Boondocking RVs cycle daily off solar; the LFP swap doubles usable capacity at half the weight, which is why it's the most common upgrade in the segment. The forecast below compounds cycle wear and calendar fade into a usable-kWh table so RV and caravan travellers can see exactly when capacity crosses the retirement threshold — and budget for it.
Fade/yr = cycle wear (20% × annual EFC ÷ 4,383 rated cycles at 85% DoD) + 1.5% calendar. Plan augmentation or replacement budgets against the usable-kWh column, not nameplate.
Engineering estimate from published standards and typical equipment data. Site conditions, equipment datasheets and measured data govern the real result — confirm with a qualified engineer.

Frequently asked questions
How much usable capacity will my battery have in 5 years?+
Typical duties: a daily-cycled LFP home battery retains ~88–92%; an NMC EV pack ~88–91%; a hot-climate hard-cycled pack can be at 80–85%. The forecast table computes your case from chemistry, cycles/day and DoD — and usable kWh, not percentages, is what runs your loads.
Should I plan replacement at 80% or 70% SoH?+
Depends what breaks first: if the battery still covers your backup/range needs at 70%, run it there — capacity fade is gradual, not a cliff. Grid contracts and EVs commonly retire at 70–80% because performance guarantees bind; home systems often run happily to 60%.
Can I slow my battery's fade once installed?+
Yes, meaningfully: keep it cool (shade, ventilation), narrow the cycling window (e.g., 20–85% instead of 0–100%), avoid storing at full charge, and limit fast charging in heat. Together these commonly stretch end-of-life by 30–50% versus careless duty.
Why does the RV / Caravan Battery Degradation Forecast ask for cycles per day?+
Because throughput drives cycle wear: 1.5 cycles/day ages a battery three times faster than 0.5 — the same chemistry can last 4 years or 12 depending on duty. Estimate cycles/day as daily energy through the battery ÷ usable capacity.
