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.
Only use 80% of your battery capacity. Draining lead-acid below 20% permanently damages it. The calculator uses this safety margin.
10+ year lifespan, faster charging, and 100% usable capacity. More expensive upfront but cheaper per year of use.
Your battery voltage (12V/24V/48V) must match your inverter input. Check compatibility before buying either.
Add your appliances and see your exact UEDCL bill, backup needs, and solar requirements in 60 seconds.
