Battery Backup Calculator Uganda | Load Shedding Solutions

Calculate the right battery size (Ah) for your backup needs in Uganda. How long will your battery last during load shedding? Get exact numbers.

Uganda load shedding can last 4-12 hours. The key question every home faces: how many battery amp-hours (Ah) do I need to keep my essentials running? Our Battery Backup Calculator takes your appliances, calculates total wattage, factors in 80% depth of discharge (safe for lead-acid batteries), and tells you the exact Ah you need. It also recommends the right battery type: lead-acid for budget setups, AGM for better performance, or lithium for long-term value.

Key Tips

80% Depth of Discharge

Only use 80% of your battery capacity. Draining lead-acid below 20% permanently damages it. The calculator uses this safety margin.

Lithium is Worth It

10+ year lifespan, faster charging, and 100% usable capacity. More expensive upfront but cheaper per year of use.

Match Battery to Inverter

Your battery voltage (12V/24V/48V) must match your inverter input. Check compatibility before buying either.

Uganda Battery Calculator - FAQs

A 100Ah deep cycle battery at 12V provides 960Wh of usable power (accounting for 80% depth of discharge). This runs: a 40W TV for 24 hours, a 60W TV + 10W lights for 14 hours, a 150W fridge + 40W TV + 20W lights for 4.5 hours. The exact runtime depends on your total load. Use our calculator to get your specific runtime based on your appliances.

Lead-acid deep cycle: cheapest upfront (UGX 400,000-600,000 for 100Ah), lasts 2-4 years. AGM: better performance and no maintenance (UGX 800,000-1,500,000 for 100Ah), lasts 4-6 years. Lithium LiFePO4: best long-term value (UGX 2,000,000-3,000,000 for 100Ah), lasts 10+ years and charges faster. For frequent load shedding, lithium pays for itself through longer life.

You need an inverter-charger that can charge the battery from the grid and switch to battery during outages. For 12V systems: connect batteries in parallel (positive to positive) to increase capacity without changing voltage. For 24V or 48V systems: connect in series. Always use proper gauge cables and a qualified electrician for installation.
