The bike uses a 12-volt motorcycle battery, typically around 4 amp-hours, such as a YTX4L-BS or an equivalent size.
The Rebel 250 (CMX250) relies on a compact sealed lead-acid battery to power the starter, ignition and lighting. When replacing, choose a 12V battery with roughly 4Ah capacity that fits the Rebel’s under-seat tray and has compatible terminal placement.
Battery type and capacity
The Rebel 250 requires a standard 12-volt motorcycle battery. The original equipment is typically a sealed lead-acid battery in the 4Ah class, commonly marketed under the YTX4L-BS designation or an equivalent model. These batteries are compact and designed to tolerate vibration on a small-displacement bike.
Replacement considerations
When replacing, verify the battery's physical dimensions fit the bike's under-seat tray, check the terminal layout (positive/negative), and ensure the new battery can be securely mounted. Some riders opt for AGM versions for better vibration resistance, while others use standard flooded lead-acid batteries as long as they are sealed and properly vented if not AGM.
Tips for choosing a battery
Key criteria: 12V rating, approximately 4Ah capacity (or higher if the tray allows), appropriate terminal positions, and a form factor that fits the Rebel's battery box. AGM batteries are common and maintenance-free, but ensure compatibility with the bike's charging system to avoid overcharging.
Confirming the exact spec
Check the owner’s manual or the original battery label for the exact model. Some riders report OEM part numbers for regional vintages, but the essential specs remain 12V and around 4Ah. If in doubt, compare the current battery’s size and terminal layout with a prospective replacement.
Summary
The 2007 Honda Rebel 250 uses a 12-volt motorcycle battery, generally around 4 amp-hours. The common OEM-equivalent is the YTX4L-BS or a similar 12V 4Ah battery. Replace with a battery of the same voltage and roughly the same capacity that fits the tray and matches terminal orientation for reliable starting and operation.
