By knowing the three different types of battery (normal startup battery, EFB and AGM), the next step will be selecting an appropriate one for your car.
1. Japanese / Korean manufactured vehicle (non-hybrid)
Simply open up the front hood and take a look at the battery label. The size (and specification) of the battery is written on top. Take note of the last two numbers and one letter that follows.
e.g. This Acdelco S80D26LH. The last two numbers is 26 followed by L (26L).
Lastly, check out if your vhielce has iStop function, and whether you are using it or not. If you are using iStop function, get EFB or AGM battery.
If you wanna check out the price of the battery, type (in this case) 26L, or simply check out the price at different retail store on your own by mentioning this size battery. (if you need a EFB or AGM, you need to mention it as well, otherwise it will be regarded as normal startup battery)

2. EU manufacture vehicle (non-hybrid)
Some brands such as Volkswagen , the battery location is at the front. Others like BMW is located at the rear (rear bonnet)
The size of these vehicle battery can normally be referred by its Ah value (especially in the case of the original battery). However, after market battery can be difficult to judge the size by referring the Ah value, as there are range of Ah offered by different battery brands.
So, the best way is to get the width and length of the battery, and check out whether you got an iStop function
At tyrehood, you can use width and length to find the list of batteryavailable.

3. Japanese / Korean manufactured vehicle (hybrid)
Besides the very high voltage battery (which is around 220V) that the hybrid car has, there is another startup battery to get the car engine on.
The location of the battery is different for different brands. Some located at the front, some located at the bottom of the seat, some located at the rear.
If the battery is located at the front, that is a good news. Not only you can check the battery model easily, the size of the battery is normally (or commonly) be found in the market.
But for those that located differently, it is cumbersome to find exactly the same size of the battery.
An example of the hybrid car used battery, which looks like a square size. But most commonly sold batteries are rectangle size in Hong Kong.
4. EU manufacture vehicle (hybrid)
Haven't seen one yet.
The size of the battery market is small. Hence there are very few brands you could choose. With the increasing number of hybrid cars and different sizes required, there could be a day when there is only one or two brands available for you to choose.
