Frequently Asked Questions

What is a Voltage Sensitive Relay (VSR)?

A Voltage Sensitive Relay automatically connects or disconnects batteries based on voltage levels. It charges the auxiliary battery from the alternator when the engine is running and isolates it when the engine is off, preventing the starter battery from being drained.

Can I install a dual battery kit myself?

Yes, most of our dual battery kits are designed for DIY installation with clear instructions and OEM-compatible parts. However, if you're not comfortable working with vehicle electrical systems, we recommend professional installation.

Are Autoscien products compatible with all vehicles?

Our products are designed to meet or exceed OEM specifications. While most are universally compatible, some battery cables are model-specific (e.g., BMW, Cadillac, Ford). Please check product details for compatibility.

Do you offer OEM/ODM services?

Yes, Autoscien provides OEM and ODM services for companies looking to brand our high-quality battery management products. Contact us for partnership opportunities.

What is the warranty on Autoscien products?

We offer a standard 2-year warranty on all products against manufacturing defects. Extended warranty options are available for bulk orders.
