Choosing a replacement battery
Fit and electrical rating both matter
Match voltage, case dimensions, terminal layout and hold-down first. For starting performance, use a replacement that meets or exceeds the published 800 CCA standard.
1. Voltage
Use the verified system voltage shown above.
2. Physical fit
Match battery tray dimensions, height and hold-down style.
3. Terminals
Confirm positive/negative terminal positions before buying.
4. Starting power
Meet or exceed published CCA when a confirmed CCA is available.
5. Multiple batteries
When the tractor uses two batteries, replace weak/mismatched pairs thoughtfully and confirm the factory cable arrangement.
?
How much CCA should a Case IH MXU115 battery have?
Quick answer
The published standard is 800 CCA, around the middle of comparable Case IH models in this researched set. A replacement meeting or modestly exceeding that figure is the sensible target. An optional/heavy-duty listing of 960 / 1300 CCA is also documented.
?
Can I install a higher-CCA battery in the Case IH MXU115?
Quick answer
Yes. A higher-CCA 12V battery is normally fine when the case size, terminal layout and hold-down match. The starter draws what it needs; the higher rating simply gives more available cranking reserve.
?
What does the Case IH MXU115 120 A alternator mean?
Quick answer
The charging system is rated at 120 A. That figure tells you the system’s maximum charging/accessory output, not the current constantly forced into the battery.
