What to know before buying

Use only with compatible 12V lead-acid batteries. The listing excludes lithium, 6V, 8V and 24V systems and says batteries below 30 AH are unsupported. Select the correct battery type, standard and CCA or AH value. It also advises checking temperature and testing after the engine has been off for about two hours for stable results.

Listing details to confirm

Listing details are contradictory or inconsistent about power: the specifications call it battery powered, while the product description says it draws power from the vehicle's 12V battery and has no built-in battery. The 12V design is stated consistently, but the power arrangement should be confirmed for the selected listing.
