Separate a refrigerator’s running watts, brief compressor-start demand, and daily watt-hours so a backup-power estimate uses the right number for each job.
Battery storage guides
Compare battery capacity, usable energy, recharge options, storage conditions, service life, and the loads that matter during an outage.
Estimate battery-backup runtime from measured loads, usable capacity, reserve, conversion loss, output limits, motor surge, temperature, age, and a real test.
Maintain a LiFePO4 backup system with manual-specific storage, temperature, inspection, firmware, load testing, fault response, and service records.
Compare lead-acid, AGM, lithium-ion, LiFePO4, and emerging battery options by complete-system use, maintenance, temperature, usable energy, and safety.
