Signs of failing automotive battery
2) The dashboard background light is flicking when you are starting up the car.
3) (in the case of BMW 523i) A warning sign telling you that there is an issue with the car battery.
(Not too sure if all the 5 series are having this system, but my BMW 523i 2007 has such function telling me about the car battery. So I believe all 5 series should later than 2007 should have such function.)
If you did not use your car for ONE month (or around, some probably less), you probably couldn't start up the car
The above are common signs that your vehicle battery is failing. Some vehicle owners claimed they did not experience these signs and the battery still fails to start up the car. But most of whom I have surveyed shows that drivers did not observe their vehicle signs of start up.
And you should NOT use the time installed to decide changing the battery as external factors may affect and speeds up battery failing.
With a year experiment and data obtained from customers, automotive battery usage is really long. So long that I believe the current price that I am selling is a little too low, so I have decided to mark up a little more at the end of this year.
For EV 12V battery, I have not experimented anything yet as I do not have any EV to be tested. Some mentioned that their 12V battery lasted at most only 2 years, in which I do not think it will be the case. Afterall, a hybrid do normally use longer than 2 years commonly. But I do not have any data to find out the reason at this moment.
汽車電池需要更換的跡象
1) 著車起動時比平時長
2) (著車起動時)錶版背景燈會閃下閃下
3) (BMW 523i) 錶版會出警告燈話粒電有問題
(不知其他5系是否都有相同系統但2007年的BMW 523i 就有這功能. 相信07後的都應該有這功能)
如果部車放置(大約/可能更短)一個月, 您應該係著唔到車.
上面為電池有問題都通常會見到既情況. 部分車主話從未見過以上情況出現但都著唔到車. 大部分我訪問既車主, 著車時其實從未留意過著車情況及錶版.
另外提提唔好用安裝時間以作判斷幾時換電池, 因為有其他不同因素會影響電池, 加速電池損耗.
經過一年的實驗及數據來源自客戶, 汽車電池好多時候係可以用好耐的. (應該係時間要加一加價).
因為冇電車用, 所以電車既 12V 電池冇實際實驗過, 但聽聞都只係用到2年. 理論上我就覺得應該唔止. 因為混能車好多時都唔止2年. 但冇數據得知點解.
