Setup & Connection
Where is the battery of a car located?
1. Most models hold the battery in the engine bay, under the
hood, in one of the front corners. See battery location ①
and ② in Figure 4.1.1.
2. To balance uneven weight distribution, some
manufacturers hold the engine in the trunk. See battery
location ⑤ , ⑥ , and ⑦ in Figure 4.1.1. In this case, the
battery may have a plastic cover that should be removed
prior to any testing.
3. For other models, the battery might be stored underneath
the rear seat. See battery location ④ in Figure 4.1.1.
4. For some vehicles, the battery can be located underneath
the passenger seat. See battery location ③ in Figure 4.1.1.
● DO NOT TEST THROUGH THE JUMPSTART POSTS. For
models that hold the battery under the seat or in the
trunk, the manufacturer usually includes jumpstart
connector conductor posts under the hood (See
Figure 4.1.2) to make jumpstarting easier. However,
to ensure data accuracy and operation safety, DO
NOT CONNECT THE BATTERY TESTER TO THE JUMP-
START POSTS.
