It depends on four key variables. Understanding each helps ISPs choose the right battery capacity for different deployment areas.<\/p><ol><li><strong><b> Battery Capacity (Wh or mAh\/VA)<\/b><\/strong><\/li><\/ol><p>Capacity is the fundamental measure of runtime. It is expressed in several ways:<\/p><ul><li>Wh\u00a0\u2013 The most practical unit because it directly represents energy. Formula: Wh = V \u00d7 Ah.<\/li><li>Ah\u00a0\u2013 Common for lead-acid batteries. Example: a 12V 7Ah battery stores 84 Wh (12\u00d77).<\/li><li>mAh\u00a0\u2013 Often used for small lithium-based mini UPS units. Divide by 1000 to get Ah, then multiply by voltage.<\/li><\/ul><p>Although consumer products are often advertised in mAh, Wh is the true measure of total energy after accounting for battery voltage.<\/p><ol start=\"2\"><li><strong><b> Total Power Consumption of Modem + Router<\/b><\/strong><\/li><\/ol><p>Most ISP-provided modems, ONTs, and routers have very low power draw. Typical total consumption ranges from 5W to 15W. However, high-performance routers or multi-port ONTs can consume 18\u201325W.<\/p><ul><li>To determine actual consumption: Check the label on each device\u2019s power adapter. Look for \u201cOutput: V and A\u201d. Multiply voltage by current to get maximum power.<\/li><li>Example: 12V 1.0A = 12W maximum. Actual operating power is usually 60\u201380% of that value.<\/li><\/ul><ol start=\"3\"><li><strong><b> Efficiency Losses and Inverter Type<\/b><\/strong><\/li><\/ol><p>The UPS architecture determines how much of the battery capacity actually reaches the router. The efficiency of the mini UPS itself reduces available energy.<\/p><ul><li><b><\/b><strong><b>DC Mini UPS (direct 12V)<\/b><\/strong>\u2013 Because modems and routers already run on low-voltage DC, no AC-to-DC conversion is needed. Operating efficiency is 90\u201395%.<\/li><li><b><\/b><strong><b>AC Mini UPS (120V\/230V output)\u00a0<\/b><\/strong>\u2013 Battery DC must be inverted to AC, then the device\u2019s own adapter converts AC back to DC. This double conversion loses 15\u201330% of energy.<\/li><\/ul><p>Whenever possible, choose a\u00a0DC mini UPS\u00a0that matches your equipment\u2019s native voltage (usually 12V). This gives you 10\u201320% longer runtime for the same battery capacity.<\/p><ol start=\"4\"><li><strong><b> Battery Lifespan and Temperature<\/b><\/strong><\/li><\/ol><p>Battery chemistry and environmental conditions significantly affect runtime.<\/p><ul><li><b><\/b><strong><b>Lead-acid batteries\u00a0<\/b><\/strong>\u2013 Traditional lead-acid degrades quickly under deep discharge cycles.
