汽車電池 - 種類 Type of Automotive Battery

(English version below)

對於汽車電池, 您有幾熟悉?

汽車電池可以用到幾耐?

可以用幾長時間?

日本製或歐洲製就一定係最好?


未繼續答更多既問題之前, 首先大家都一定要知最基本既野, 就係到底有咩電池類別, 同埋應該揀邊一個類別.


總括黎講最常用既汽車電池分為三類別 - 普通電池, EFB電池, 同埋AGM電池.

(仲有另外兩款, Deep cycle 同埋 Lithium. 呢兩款就睇下會唔會遲啲再講)

另有三款分別為 Deep Cycle,  Lithium, 及 Gel

Deep Cycle 「深循環電池」或「深放電電池」係常用於船上. 當年 Tesla Model S 都有用 Deep Cycle 電池. 但最近得知之後有啲款開始, 已經由 deep cycle 改為其他款既電池.

Lithium 鋰電池 係出面比較多人聽到, 話特別好既電池, 話耐用. 係電動車未出現之前已經有傳. 但有冇諗過點解係汽油車時代都仲未通行? 但現時電動車時代都冇用黎做12V. 原因, 可以了解下您自己部手提電話就知道.

Gel 電池係電單車常用既電池. Gel 唔係 AGM 電池. 由於我從來冇見過, 所以我都唔知價錢同是否岩用於 Benz 的輔助電池


呢三款入面應該揀邊一款?

如果您部車係沒有iStop 功能(中文好似係叫 停車時自動熄匙功能), 就只需要用番普通電池就夠.



(2024年12月2日更新)
市面上現有的電池, 多數都係韓國製, 日本製, 歐洲製, 及印度制. (部分牌子已經有中國製)
普通電池當中, 也有兩款唔同既分別: -> Calcium () 料, 及 Silver ()料.

Calcium 料係現時比較普遍係電池當中, e.g. Eneus, Solite, Acdelco 等.... 簡寫為 CMF
Silver 料通常會見到係 Amaron, Varta 牌子. 

兩者之間對應唔同使用方法. 但Silver 就係其中一個原因點解令到個款電池特別貴啲. 所以有啲人一聽到 Amaron 係印度製既電池, 即時就黎左個偏見, 點解印度製既, 仲貴過韓國製..... 

之於兩者之間既分別.... 我就唔詳細係呢到講了.



如果係EFB或AGM電池, 電池上都會印有 EFB, AGM 既字眼. 所以好易認得出.


現時香港有9成幾既汽車用電池都係 "免維護(Maintenance Free)". 即係用家無需要去睇電池入面液體夠唔夠, 唔駛好似以前咁需要加蒸餾水.

私家車同van 仔用既電池都只會搵到"免維護", 除左部分貨車都仲可以買到水電. 不過對於個啲想買水電既車主, 有冇諗過唔係真係次次都俾您加到水就可以著番部車 ?

汽車電池及其他服務檢查只限於Tyrehood網上客戶並落訂購買至少兩條輪胎(並未有要求戥呔前移除鉛)及電池(電池牌子需要在Tyrehood網站上銷售, 如 Acdelco, Eneus, Solite等)

其他未有預訂及直接於門店安裝電池的客戶請直接向供應商查詢產品問題.


汽車業務通常分為輪胎及電池(簡稱呔鋪, 為零售服務), 維修(簡稱車房), 及汽車美容服務. 

Tyrehood 現時業務為呔鋪, 並沒有其他服務如更換油服務提供.

How well do you know automotive batteries in the market?

How long can it be last?

How long can it be used?

Those made in Japan or made in Europe are the best recommendation.... or is it?


Before coming into further questions, it is a basic to know what type of battery you actually need for your vehicle.


In general, there is 3 types commonly used for your vehicle - The standard battery, EFB, and AGM.

(There is another 2 types of batteries, deep cycle and Lithium which maybe explained in the future)

Let's make a quick explanation on another three types of battery that can also be found in the market. 

Deep Cycle battery is normally used in boat. Tesla Model S also used Deep Cycle battery. But hearing from customers that latest models are swapping deep cycle with other types of batteries.

Lithium batteries are rumored to be especially good and durable even before electric vehicle released. Yet, it is not commonly installed in petrol vehicle, and not even in electric vehicle as originally equipped for 12V. For the reason, you could check out your smartphone for it.

Gel battery normally used in motorcycle. Gel is not AGM battery. I have never seen one before so I do not know if it can be used in Benz as auxiliary battery.


So which one should you choose?

If your vehicle do NOT have an iStop function (idling stop function, which automatic switch off your engine when your vehicle comes to a stop), a standard battery is enough for your vehicle.


(2 Dec 2024 Update:)
These type of batteries commonly made in Korea, Japan, India (with some brands already made in China)

There are two different materials built for normal battery: Calcium, and Silver.

Calcium is commonly found in battery. E.g. Eneus, Solite, Acdelco etc.... short form CMF.
Silver can be found in Amaron, Varta brand.

These two offers different uses. But silver is one of the reasons why the battery is a little more expensive.
And for those two differences, I am not going into detail.



It is also easy to classify the type of battery by looking at the labels. If it is a EFB or a AGM, there will be label imprinting on it. 


In these days, the way that automotive battery work is now known as "Maintenance Free", which implies users do not need to keep track of the liquid level of the battery. (unlike last time when you need to top up the battery using distilled water)

The after market batteries are all "Maintenance Free" except one or two brands available in Hong Kong market. However, those non Maintenance Free batteries are only available to Long Lorry vehicle and Truck. 


Battery inspection and other inspection service are only available to Tyrehood customers who at least pre-purchase two tyres and one battery (battery brands must be available on Tyrehood website such as Acdelco, Eneus, Solite etc).

For walkin customer, please contact the supplier for any query or questions related to your product issues.

-------------------------------

Out of topic, but something to be known. Automotive industry in Hong Kong is classified into three categories - tyre retail store, automotive garage, and automotive detailing.

Tyrehood is a tyre retail store at this moment. Therefore Tyrehood do not provide services such as oil changing which are provided by a garage.
