請問汽車電瓶在車子不發動之下,可以聽音響多久?
如果以60AH來算,最後還要能發動.
另外沒發動點煙器會供電嗎?若又沒發動之下,用12V轉110V 再接筆記型電腦,可以用很久嗎(我的筆記型電腦電池壞了)? 有人試過嗎?謝謝! |

我常常這樣，不過我只聽半小時到一小時就發動了，我可不想很丟臉的在路邊揮手 (揮過3次了)...

真的可以聽一小時?那接筆記型電腦應可以很久才對? 假設25w,60ah可以用多久,有人會算嗎? |

一顆電瓶充到飽大約有400A的電
電壓是12v... 也就是總共4800 W 然後再看看筆電消耗多少W/H

60AH 以60A放電1hr 反過來就是60hr W=V*A 電腦吃掉的安培數 我不知道  PS:要確定電瓶是充滿電的 |

筆記型電腦如果是12v / 3a 那就是 60/3 = 20h 囉? |

當中還要算進能量的損耗...
因為你是12V--->110V--->12V 這之間一定會有部分轉為熱能... 所以,以充到飽的400A電池來說,大約18~19小時

真實數很難抓吧..一方面電瓶有沒有充滿是誰也不知道.再說電瓶用一用蓄電能力也會慢慢減低.能撐多久誰也不知道
我個人是不會在熄火沒開空調的情況下聽超過一小時..電瓶沒電拋錨在路邊不是很好玩..... |

開窗戶關電門.... 最長聽大約半小時.......
 因為車子裡面很熱, 沒開冷氣坐著皮椅動不動就會流汗...
