一个月前刚在AUTOBARN买了一个新电瓶，然后昨天去做保养电池检测出来BATTERY LIFE只有81%
请问这个正常么？一个月就用了20%，那岂不是再过4个月我电池就玩完了。现在怀疑装的时候就不是新的。
麻烦懂得筒子解答下
谢谢大家的回复
刚才打电话给AUTOBARN，说让我放心因为电池有36个月的WARRANTY, 如果在保质期间坏掉了可以免费更换，所以就无所谓了

拿回去问商店啊

半年多以前去做保养，那人说检测我电瓶，需要换，那时我的电瓶刚换没多久，就没理他。现在照样用。
电池检测准不准不知道，做保养的想骗钱也有可能。

怕商店的人扯皮，而且我又不是很懂，所以先想咨询下然后回去找他们

我这个是人家机器数据打的单子上显示的

There are essentially two ways to test a battery. The "old fashioned way" is to use a Load Tester. For accurate results with a load tester, the battery must first be recharged before it is tested. The tester applies a calibrated load to the battery (typically half the battery cold cranking amp [CCA] capacity or three times its amp/hour rating). While the load is applied, the tester monitors battery voltage. If the battery voltage drops below 9.6 volts during the test, the battery is BAD and needs to be replaced. If the voltage remains about 9.6 volts, the battery is GOOD and can be returned to service.
The other (and must faster) method for testing your battery is to use an electronic "conductance" tester like the one shown here. A conductance tester sends a alternating frequency signal through the battery to determine the condition of the cell plates inside the battery. As a battery ages, its internal conductance declines. Shorts, opens and other cell defects also reduce conductance, so measuring conductance gives an accurate indication of battery condition. The best feature of this type of test is that the battery does NOT have to be recharged prior to testing. Most conductance testers will give an accurate reading even if the battery is almost dead.
Ok so lets look at the two types of testers involved here
Conductance tester which is the OE aproved norm nowadays
It basically sends a small current in through one side of the battery and measures what comes out the other side
Theres some advantages to this system -
1 - you can test the battery in any state of charge
2 - you cannot damage the battery with this system
3 - If its a high qaulity unit your test is pretty accurate
The other type is load tester and yes they work but there are disadvantages
1- for an accurate test the battery must be fully charged and left of charge for atleast 6 hours
2- if done incorectly you can damage your battery
Now let me say this - both types of testers depend on two things to be succesfull
1- a high qaulity tester
2 - a competent technician performing the test
希望对你有帮助，问问做保养的用的那种方法测得，再打电话给autobarn，把你的情况告诉他们，看他们怎么处理。

很好奇 这个怎么测准确

多跑跑长途自然就好了

电瓶就是发动车子的时候用，买的时候大一个规格买

鬼子只相信仪器，不相信大脑。

最好看一下电池的标签或receipt上有没有写36 month warranty，免得他们以后不认帐
