Visual Check
Look for movement, damage, swelling, moisture, loose cables and heat marks.
A practical routine to protect battery performance, charging reliability and vehicle uptime without ignoring safety warning signs.

Daily Checklist
Look for movement, damage, swelling, moisture, loose cables and heat marks.
Confirm normal charger completion and investigate major changes in charging time.
Tyre pressure, brakes, bearings and alignment affect energy use and safety.
Plan realistic load, distance and charging opportunity for the vehicle.
Maintenance Rhythm
| Every trip | Observe power delivery, warning indicators, smell, noise and unexpected heat |
|---|---|
| Daily | Inspect visible battery mounting, charger cable, connector and vehicle tyres |
| Weekly | Check for loose connections, abrasion, water exposure and changes in runtime |
| Periodically | Qualified inspection of wiring, terminals, protection, brakes, suspension and charging supply |
| After impact or water exposure | Stop and arrange inspection before reuse |
| During long storage | Follow model-specific state-of-charge, environment and inspection guidance |

Protect Range
Low tyre pressure, dragging brakes, overloaded operation, poor wheel alignment, bearing problems, high speed and harsh acceleration can increase energy use. A shorter route does not always mean a battery fault.
Track normal charging time, route, load and runtime. A consistent record helps distinguish operating changes from battery, charger or vehicle problems.
Helpful Answers
Possible causes include route/load changes, tyres, brakes, alignment, temperature, charger behavior, battery aging, connection issues or faults. Inspect the complete system.
Follow the exact battery guidance. Repeated deep discharge may reduce service life for many battery systems.
No. Chargers should be clearly assigned to compatible battery models and kept in good condition.
Vehicle, battery serial, charger, driver, route, charge time, service, warning events and repairs are useful.
