🔌 Performance & Load-Shedding Use
For inverter or UPS use, the Royal DC31 battery can power up to 350 W for 4 hours when paired in a 2-battery setup. Proper recharge time (8 – 16 hours) between load-shedding events is essential to maintain long battery life. Continuous operation at low charge levels will shorten lifespan, just like running tyres with low pressure.
Pro Tip: Switch off non-essential appliances during load-shedding to extend runtime and preserve your battery cycles.
⚠️ Usage & Maintenance Tips
-
Recharge to 90 % + after each load-shedding cycle
-
Use a smart inverter/charger with correct voltage settings
-
