How To Install Battery Hold Down. The top hold down bolt has an adjustable length of up to 8-inches. We picked up a universal hold down kit from the local NAPA Auto Parts Store to secure the battery.

This one uses L-bolts and can adjust to anywhere between 55 to 85 inches. They are suitable for a range of applications. Install battery in vehicle making sure that the thermal guard is present and battery is properly positioned on battery tray 2.
Remove thermal guard from battery.
If you tightened your battery hold-down the last time you replaced the battery thats a good start. INSTALLATION When replacing battery the thermal guard MUST be transferred to the new battery. When I bought my AGM battery its electrical capacity was larger then OEM but dimensionally smaller. After putting in a new battery I searched but was unable to find an anchoring hole for the hook end of the L-shaped rod that is used for holding down the hold-down clamp on top of the battery.
