The 2016 Toyota Rav4 Hybrid has a tightly designed battery compartment, making finding a replacement battery a challenge. This article details a successful installation of an Interstate Battery MTP-86 in a 2016 RAV4 Hybrid, outlining the modifications and additional parts required for a proper fit.
MTP-86 Installation Process: Modifications and Parts
While not a direct replacement, the Interstate Battery MTP-86 can be installed with some adjustments. The 2016 RAV4 Hybrid’s battery compartment seems designed for a battery with a base footprint no larger than 222mm by 173mm (8 3/4in x 6 13/16in). The MTP-86, while listed as 9 1/16in long, actually measures 8 3/4in at its base, fitting the length requirement perfectly.
The width presents a slight challenge. Ribbing at the base of the MTP-86 can interfere with a flush fit. While some ribbing can be trimmed, a 3/4in wood spacer eliminates this need and ensures a secure fit. Additionally, the MTP-86 is shorter than the original battery; the spacer raises it enough for the hold-down bracket to engage correctly.
Vent hose configuration also requires modification. The OEM battery has a single vent port, while the MTP-86 has two—one on each side. Two GM-style battery vent hoses, a short extension hose, a vacuum hose “tee” (replacing the OEM elbow), and a hose connector are necessary. The positive terminal vent hose may slightly touch the hold down bracket; careful alignment is crucial during installation.
Securing the MTP-86 in the 2016 RAV4 Hybrid
The shorter height of the MTP-86 necessitates the use of a wood spacer to ensure proper engagement with the hold-down bracket. This spacer effectively raises the battery to the correct height, allowing for a secure and stable installation within the compartment.
Sourcing the Necessary Parts
Local Interstate Battery distributors are a valuable resource for this project. They typically provide the GM-style vent hoses with the MTP-86 purchase. The remaining components—the hose connector, tee, and wood scrap—are commonly available and may already be on hand.
Conclusion: A Viable Solution
The Interstate MTP-86 offers a viable alternative for the 2016 Toyota RAV4 Hybrid’s battery. Although minor modifications are required, the process is relatively straightforward with readily available parts. This solution provides a reliable power source for your RAV4 Hybrid.
