Frequently Asked Questions - Backup Power Batteries
Yes, LiFePO4 batteries can replace lead-acid UPS batteries with significant advantages. However, you need to ensure voltage compatibility (12V, 24V, or 48V) and adjust the float charge voltage setting (13.6V for 12V systems instead of 13.8V for lead-acid). Some modern UPS systems have LiFePO4 battery settings. Contact us for compatibility guidance with your specific UPS model.
Backup runtime depends on your equipment's power draw. A 12V 20Ah battery (240Wh) provides approximately: 30-60 minutes for a desktop PC (200-400W), 2-3 hours for a laptop (80-100W), 4-6 hours for a router/modem (40-60W), or 8-12 hours for network equipment (20-30W). Use our sizing calculator or consult our engineers for precise runtime estimates.
Our LiFePO4 backup batteries offer >10 years of float life at 25°C (77°F). This is 2-3x longer than lead-acid batteries which typically last 3-5 years under the same conditions. The actual float life depends on operating temperature - at 30°C, float life reduces to approximately 7-8 years, still far exceeding lead-acid performance.
Yes, our batteries are compatible with most major UPS brands including APC, Eaton, Vertiv, Tripp Lite, and CyberPower. We offer replacement batteries in standard form factors that fit existing UPS battery compartments. Our batteries support the required communication protocols (USB, serial, network) for UPS status monitoring. Contact us with your UPS model for specific compatibility confirmation.
