Products
Battery Conductance Tester
Quickly test the health of your 12V battery using advanced conductance technology. Perfect for car batteries, motorcycles, and outdoor equipment

Smart Battery Disconnect Switch
Use
Long-Term Vehicle Storage
With LILEAD’s smart battery protection switch installed, your vehicle’s battery stays safe even during long periods of inactivity—whether you’re away on a business trip or storing the car for the season. Prevent deep discharge and extend your battery’s life effortlessly.
Modified or Custom Vehicles with Complex Wiring
Aftermarket sound systems, 360° cameras, and other electronics often keep drawing power even after the engine is off. LILEAD’s smart battery protector monitors your battery voltage and automatically disconnects discharge before it drops too low—helping avoid deep drain, battery failure, and costly replacements.
Forgetting to Turn Off Car Accessories
Forgot to turn off the headlights or car accessories again? LILEAD’s smart battery disconnect switch monitors your battery levels in real time and cuts off the discharge automatically when voltage drops too low—preventing deep drain, startup failure, and costly battery damage.
Aging Wiring and Hidden Battery Drain
Old or deteriorated vehicle wiring can cause constant battery drain or even lead to dangerous short circuits and fires. LILEAD’s smart battery disconnect switch monitors the battery in real-time, cutting off discharge when needed to prevent deep drain, failed starts, or electrical hazards.
Portable 12V Battery Charger
Use
Motorcycle Charging in the Wild
LILEAD’s portable charger allows you to recharge your 12V battery using everyday items like a power bank or a smartphone wall charger. Whether you’re on the road or at home, stay powered without removing the battery.
Maintenance Charging for Seasonal Equipment
With LILEAD’s portable battery charger, you can safely maintain the charge of rarely used vehicles — like snowmobiles, lawnmowers, and ATVs — directly from a garage power outlet. It intelligently prevents overcharging and battery drain, keeping your vehicles ready for use anytime.
Emergency Reverse Charging for USB Devices
The LILEAD portable battery charger not only recharges your vehicle battery, but also reverse-charges your devices — like smartphones — during your ride. Stay powered up, no matter where you go
Easy Battery Boosting for Cars — No Removal Needed
A compact and smart solution — LILEAD’s portable charger lets you recharge your battery using a power bank. No need to remove the battery, no tools required.
"They solved every problem I’ve ever had with my battery."
I used to worry about my car battery all the time—when to replace it, how to protect it, and how to maintain it.
This brand gave me a full solution:
- A tester to check battery health
- A disconnect switch to prevent drainage
- A portable charger that even powers my phone if needed
No more guesswork. Total peace of mind.
