2017–2020 Toyota 86 Battery FAQ's

Please read our FAQs page to find out more.

Is a lightweight battery worthwhile on the ZN6 Toyota 86?

A quality AGM or LiFePO₄ can drop several kilograms from the nose of the 2017–2020 Toyota 86, improving weight distribution. Ensure adequate cold‑cranking capacity and use a rigid tie‑down; add heat shielding if the car sees extended under‑hood heat.

Can I relocate the battery to the trunk on the ZN6 Toyota 86?

Yes, with proper‑gauge cable, a fused disconnect near the battery, and grommeted pass‑throughs. If inside the cabin, use a sealed AGM or vent the enclosure externally.

What charging system checks should follow a battery upgrade on the ZN6 Toyota 86?

Clean grounds, verify alternator output under load, and confirm voltage at idle with lights and fans on. Stable voltage prevents ignition or pump issues at high RPM.
