Group 27 vs 31: fitment checks, runtime realities, and when LiFePO4 beats a size upgrade.
LiFePO4 guidance on safe discharge, deep discharge risks, and recovery for RV/marine and home energy storage.
A multimeter-based guide to fix RV batteries not charging on shore power—converter, fuses, disconnect, wiring.
Step-by-step multimeter battery test with voltage charts, load checks, charging checks, and troubleshooting.
Ah (amp-hours) is a battery capacity rating—how much current a battery can deliver over time under stated conditions. For the most practical runtime estimates, convert capacity to energy using Wh = V × Ah, then estimate runtime with hours ≈ Wh ÷ W, adjusting for usable DoD and system losses.
