How It Works

Battery lifespan depends heavily on depth of discharge (DOD) and chemistry. LFP (lithium iron phosphate) batteries last 5,000-8,000 cycles at 80% DOD, while lead-acid manages only 500-1,500 cycles at 50% DOD. Higher temperatures accelerate degradation. Keeping batteries below 80% DOD and in a temperature-controlled space significantly extends their life.
