What's the Ah, Ampere What the relationship of them <\/h2>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Many customer come to ask me :\u00a0 Whats Ampere your Lifepo4 Battery , i think they ar are not clear to the\u00a0 difference of the\u00a0 Ah. Ampere, Wh\u00a0<\/h4>

Regarding the terms\u00a0Ah<\/strong>,\u00a0Ample<\/strong>, and\u00a0Wh<\/strong>\u00a0you mentioned, let me first clarify:<\/p>

  • Ah<\/strong>\u00a0stands for\u00a0Ampere-hour<\/strong>, a common unit of battery capacity.<\/p><\/li>

  • Wh<\/strong>\u00a0stands for\u00a0Watt-hour<\/strong>, a common unit of electrical energy.<\/p><\/li>

  • Ample<\/strong>\u00a0is not a standard electrical unit. It might be a misspelling or misreading of\u00a0Ampere<\/strong>\u00a0(the unit of electric current). In everyday conversation, people sometimes say “ample capacity” as a phrase, but it is not a unit.<\/p><\/li><\/ul>

    Below, I assume you meant Ah<\/strong>\u00a0and\u00a0Wh<\/strong>, as well as their relationship with current (A, Amperes).<\/h4>

    1<\/p>

    Unit<\/th>Meaning<\/th>Physical Quantity<\/th><\/tr><\/thead>
    A<\/strong>\u00a0(Ampere)<\/td>Electric current<\/td>Current<\/td><\/tr>
    Ah<\/strong>\u00a0(Ampere-hour)<\/td>Battery capacity = Current \u00d7 Time<\/td>Electric charge<\/td><\/tr>
    Wh<\/strong>\u00a0(Watt-hour)<\/td>Electrical energy = Power \u00d7 Time<\/td>Energy<\/td><\/tr><\/tbody><\/table><\/div>

    2. Conversion Between Ah and Wh<\/h2>

    The conversion requires the\u00a0voltage (V)<\/strong>.<\/p>

    Wh=Ah\u00d7V<\/span>Wh<\/span><\/span>=<\/span><\/span>Ah<\/span><\/span>\u00d7<\/span><\/span>V<\/span><\/span><\/span><\/span><\/span><\/span>Ah=WhV<\/span>Ah<\/span><\/span>=<\/span><\/span>V<\/span>Wh<\/span><\/span>\u200b<\/span><\/span><\/span><\/span><\/span><\/span><\/span><\/span><\/span><\/p>

    Examples:<\/h3>

    • A\u00a012V, 100Ah<\/strong>\u00a0battery<\/p>100\u00a0Ah\u00d712\u00a0V=1200\u00a0Wh<\/span>100<\/span>\u00a0<\/span>Ah<\/span><\/span>\u00d7<\/span><\/span>12<\/span>\u00a0<\/span>V<\/span><\/span>=<\/span><\/span>1200<\/span>\u00a0<\/span>Wh<\/span><\/span><\/span><\/span><\/span><\/span>

      That is 1.2 kilowatt-hours (1 kWh = 1000 Wh).<\/p><\/li>

    • A\u00a0500Wh, 50V<\/strong>\u00a0battery<\/p>50050=10\u00a0Ah<\/span>50500<\/span>\u200b<\/span><\/span><\/span><\/span><\/span>=<\/span><\/span>10<\/span>\u00a0<\/span>Ah<\/span><\/span><\/span><\/span><\/span><\/span><\/li><\/ul>

      3. Relationship Between Ah and Current (A)<\/h2>

      Ah tells you how many hours a battery can last when discharging at a given current.<\/p>

      Discharge\u00a0time\u00a0(h)=Capacity\u00a0(Ah)Current\u00a0(A)<\/span>Discharge\u00a0time\u00a0(h)<\/span><\/span>=<\/span><\/span>Current\u00a0(A)<\/span>Capacity\u00a0(Ah)<\/span><\/span>\u200b<\/span><\/span><\/span><\/span><\/span><\/span><\/span><\/span><\/span><\/p>

      Examples:<\/h3>

      • A\u00a010Ah<\/strong>\u00a0battery discharged at\u00a02A<\/strong>\u00a0\u2192 runtime =\u00a010\/2=5<\/span>10\/2<\/span>=<\/span><\/span>5<\/span><\/span><\/span><\/span>\u00a0hours.<\/p><\/li>

      • Discharged at\u00a05A<\/strong>\u00a0\u2192 runtime =\u00a010\/5=2<\/span>10\/5<\/span>=<\/span><\/span>2<\/span><\/span><\/span><\/span>\u00a0hours.<\/p><\/li><\/ul>

        4. Summary Table<\/h2>
        \u00a0<\/div>
        \u00a0<\/div><\/div>
        Conversion<\/th>Formula<\/th>Required Information<\/th><\/tr><\/thead>
