Case IH DX45 Extra Battery Notes
Replacement note
For the Case IH DX45, match the replacement battery to the captured spec: 12 V, Group 31. Physical fit, terminal layout and hold-down fit still matter
Battery location
The battery on the Case IH DX45 tractor is typically located under the seat. This placement is common for many tractors in this series
Bad battery symptoms
Case IH DX45 tractors with weak or failing batteries often show no dash glow-plug lights, no signal to the starter solenoid, and constant 12 volts at the starter even when the key is off
Safe removal note
Disconnect the negative cable first, then disconnect the positive cable. Install the new battery, connect the positive cable first, then reconnect the negative cable last. That reduces the chance of shorting a tool against the frame
Official information note
Mistakes do happen. Battery specs can change by year, engine, market, terminal layout and installed options. Check the old battery label, operator manual, parts book and official caseih.com website before ordering a replacement battery.
