What to match when buying
Use a heavy-duty 12 V starting battery in BCI Group 31 with about 1000 CCA (or higher), provided the case dimensions, hold-down and terminal orientation match. AGM is a good upgrade for vibration resistance; verify the machine serial number before purchase.

HOW
How to replace the battery
Basic replacement procedure
Park on level ground, lower the lift arms/attachment, stop the engine, remove the key and isolate electrical power. Open the battery access, disconnect the negative cable first and then positive, remove the hold-down and lift out the battery. Clean the tray/terminals, install the replacement securely, connect positive first and negative last, then verify charging voltage and starting operation.

Bad battery symptoms
Signs the battery may be failing
Common signs are slow or no cranking, repeated clicking from the starter/solenoid, dim or flickering lights/display, electronics resetting during crank, needing frequent jump-starts, rapid self-discharge, corroded/swollen battery case, or resting voltage that quickly falls under load. Confirm cable condition and alternator output before condemning the battery.
?
What battery size fits the Case 1840?
Quick answer
Group 31. Best available fitment is based on closest same-brand/model-family match (1845 C); confirm tray dimensions, terminal layout, and serial number before ordering.
?
How many CCA does the Case 1840 need?
Quick answer
1000 CCA. Best available fitment is based on closest same-brand/model-family match (1845 C); an equal-or-higher CCA replacement is acceptable if the physical size and terminals match.
?
What voltage battery does the Case 1840 use?
Quick answer
12 volts. Skid-steer starting/charging systems for this model family use a 12 V battery system; confirm serial-specific configuration before replacement.
