Match the old battery and the vehicle manual
- Check the case size, hold-down, clearance, terminal orientation and any vent requirement. Confirm the specified chemistry and minimum cold-cranking amps.
- If the truck has start-stop or a battery management system, check the manual for approved replacements and any registration procedure.
- If the truck still cranks slowly, check the charging system, terminal connections and battery condition before choosing a larger unit. See NHTSA winter vehicle preparation.
