Replacement Battery For Hondata S300 V1

This purchase is for a new replacement battery for your Hondata S300 V1 unit. It is very well known that the older V1 s300's have an on board battery that goes out very frequently once they pass their 5 year lifespan. This means all V1 units being used right now should already have a new battery or desperately NEED one replaced.  

*Purchase is for the battery ONLY, Hondata boards and labor necessary for install not included.*

*It is 100% your responsibility to determine if your Hondata is in need or compatible with the replacement.*

*If you do not have the equipment or ability to install components into an ECU please do not hesitate to purchase our full install service where we perform the work for you!*
