Jump-starting a dead battery typically doesn't take much time, but the exact duration can vary depending on several factors. It usually takes a few minutes to establish the connection between the working vehicle's battery and the dead battery, and then a few more minutes for the dead battery to receive enough charge to start the engine. However, if the dead battery is severely depleted or damaged, it may take longer, or it might not work at all. It's essential to follow safety precautions and ensure proper connections when jump-starting a vehicle.
原装电池Panasonic用了九年,2020年换了Energizer. 换不到两年就死了.2022年11月换了Kirkland , 才10个月, 上个星期车又发动不起来. 目前情况是:电池完全没电,也充不进电.Jump Start也发动不起来.
打算再买个电池看能不能发动起来? 我的问题是,为什么电池 1-2 年就死了? 为什么Jump Start也发动不起来? 请各位观众指教.谢谢.
要确诊就把电池拿去autozone charge up and get tested, test its alternator too.

疫情之后，用车少了。电池经常处于未充满状态，寿命就会减少。
建议买个充电器，隔段时间充一下。
一个完全死掉了的电池有多大的内阻？就算有另外有一个好电源充着电，起动时的大电流通过死电池的之后starter还能分到多少电压？
先去搞搞懂死电池在不在起动电路上。
电池完蛋的太频繁，发电机就有嫌疑了；但如果jump正确，但不启动，启动机就有可能不行了，总之环环相扣
方方面面有诸多可能性。假如自己有DIY能力的话，尝试排除试错法，比如jump时启动马达crank声音不正常，试试换件？
包括车门彻夜没关，电池放到0的情况。
当然不排除有的发电机功率小，并车的电池也不足，或者线接触不好。不知道你们说的启动器是什么，如果是starter，那大小与启动车没有关系。
要想缺电的电池不作为负载，断开就是了
以前发过几次关于电池的帖子，收收吧。
俺说，反正是会员，叫A AA来试一下吧……

死车电池吸收了供电车的发电机/电池的相当部分电流，分给启动器的电流有可能不够大而不能启动死车。换个说法，供电车只是怠速的话它的引擎输出功率不大它的发电机输出功率自然也不大，这不大的功率在短时间被死车的极端亏电电池分走了，给启动器的功率不足以启动死车引擎
