    Frequently Asked Questions<\/span><\/strong><\/span>
    \n<\/b><\/strong><\/span><\/strong><\/span><\/strong><\/span><\/p>\n

    Why does a 260Ah battery show 230Ah on the label?<\/b><\/span><\/strong><\/span><\/strong><\/span><\/strong><\/span><\/strong><\/span><\/p>\n

    The battery has different capacity ratings because it is tested under different discharge durations. The UIT28036 delivers 260Ah at C20 and 230Ah at C10. Since C20 measures capacity over a longer discharge period, the battery can deliver a higher Ah value. C10 measures capacity over a shorter discharge period, resulting in a lower Ah rating. Both values are correct and represent the same battery under different testing standards.<\/span><\/span><\/span><\/span><\/b><\/span><\/b><\/p>\n

    What does 36 + 24 months warranty mean?<\/b><\/span>
    \n<\/strong><\/span><\/strong><\/span><\/strong><\/span><\/strong><\/span><\/strong><\/span><\/p>\n

    Like the rest of the UIT range, the UIT28036 carries 36 months of free replacement warranty followed by 24 months of pro-rata coverage.<\/span><\/p>\n

    What is the difference between C10 and C20 battery ratings?
    \n<\/b><\/span><\/strong><\/span>C20 and C10 simply reflect different discharge durations used in testing. Because C20 discharges more slowly over 20 hours, it yields the UIT28036’s higher 260Ah figure, versus 230Ah at the faster C10 rate.<\/span><\/span><\/span><\/p>\n

    Is this a solar battery or an inverter battery?
    \n<\/b><\/span><\/strong><\/span><\/p>\n

    The UIT28036 is a tubular battery designed for both applications. It can be used with compatible home UPS systems, inverter systems, and solar inverters. The C20 rating is commonly referenced for inverter batteries, while the C10 rating is frequently used for solar battery specifications.<\/span><\/p>\n

    Can I use this battery with any inverter?
    \n<\/b><\/span><\/strong><\/span>Given its size, confirm your inverter is rated to charge a battery of this capacity before installing the UIT28036 \u2014 otherwise it’s compatible with standard 12V tubular-ready inverters.<\/span><\/p>\n

    Is a tubular battery better than a flat plate battery?<\/b><\/span><\/strong><\/span><\/p>\n

    For high-capacity batteries especially, tubular plates offer a real durability advantage over flat plates \u2014 better cycle life, steadier charging efficiency, and a longer working life overall.<\/span><\/p>\n

    How often does this battery require maintenance?<\/b><\/span><\/strong><\/span>
    \nGiven its size, the UIT28036 still requires only basic upkeep \u2014 periodic electrolyte checks and distilled water top-ups when levels run low.<\/span><\/p>\n

    How long will a 230Ah inverter battery provide backup?
    \n<\/b><\/span><\/strong><\/span>As UTL’s largest battery, the UIT28036 offers the longest potential runtime in the range, though the exact hours still depend on your total connected load and inverter efficiency.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
