The following are the top 20 best practices owners can adopt to maintain their electric vehicle batteries:
| Rank | Practice | Explanation |
| 1 | Avoid extreme charging: Aim for 20-80% daily charge and minimize frequent full charges (100%) or deep discharges (below 20%). | Battery lifespan is maximized within this moderate range. Extremes stress the battery cells. |
| 2 | Optimize preconditioning: Use pre-conditioning when available to heat or cool the battery while plugged in before driving. | This improves battery performance and efficiency, especially in extreme temperatures. |
| 3 | Minimize fast charging: While convenient, use fast charging sparingly as it can generate heat and stress the battery. Opt for slower charging whenever possible. | Slower charging allows for more gradual heat dissipation and less battery stress. |
| 4 | Park in moderate temperatures: Whenever possible, park in a shaded area or garage to avoid excessive heat or cold, which can degrade battery performance. | Extreme temperatures can strain the battery and limit its capacity. |
| 5 | Maintain recommended tyre pressure: Proper tyre pressure improves efficiency and reduces rolling resistance, minimizing stress on the battery. | Underinflated tyres require more energy to roll, increasing battery drain. |
| 6 | Perform regular software updates: Manufacturer updates often contain battery management improvements and optimizations. Keep your EV software up-to-date. | Updates can enhance battery longevity and performance. |
| 7 | Minimize unnecessary weight: Avoid overloading your EV with unnecessary cargo, as excess weight increases energy consumption and battery strain. | Lighter weight translates to less energy needed and lower battery stress. |
| 8 | Use regenerative braking: Utilize regenerative braking whenever possible to recover energy during braking and put it back into the battery. | This practice reduces energy consumption and extends range. |
| 9 | Store your EV properly: If storing your EV for extended periods, ideally maintain a 50% battery charge and park in a cool, dry location. | Full or empty batteries during storage can accelerate degradation. |
| 10 | Monitor battery health: Most EVs display battery health information. Pay attention to warnings and consult your manual for maintenance recommendations. | Early detection of potential issues allows for timely intervention and potentially prevents bigger problems. |
| 11 | Choose efficient driving habits: Avoid rapid acceleration, maintain moderate speeds, and anticipate traffic to minimize unnecessary battery drain. | Smooth, fuel-efficient driving practices conserve battery energy. |
| 12 | Plan your charging: Estimate your driving needs and charge accordingly to avoid unnecessary deep discharges or frequent full charges. | Planning helps maintain the battery within its optimal range. |
| 13 | Invest in a quality home charger: Choose a well-rated charger compatible with your EV and offer appropriate charging speeds. | Avoid unreliable or incompatible chargers that could damage the battery. |
| 14 | Clean your EV regularly: Regular cleaning helps remove dust and debris that can trap heat around the battery, potentially impacting its performance. | Proper ventilation is crucial for battery health. |
| 15 | Consider adding battery protection: Some aftermarket products claim to extend battery life, but research their effectiveness and consult your manufacturer before using them. | Consult experts and ensure chosen products are compatible and safe for your EV. |
| 16 | Beware of extreme weather: If possible, avoid exposing your EV to extreme weather conditions, as this can affect battery performance and lifespan. | Seek shelter during storms or park in moderate temperatures whenever possible. |
| 17 | Understand your EV’s battery warranty: Familiarize yourself with your EV’s battery warranty terms and coverage to know what’s included and any specific maintenance guidelines. | Knowing your warranty rights can help navigate potential issues. |
| 18 | Consult your EV manual: Each EV model has specific recommendations for battery care and maintenance. Refer to your manual for detailed instructions and best practices. | The manufacturer’s guidelines are tailored to your specific vehicle and ensure optimal battery health. |
| 19 | Seek professional help if needed: If you experience any unusual battery behaviour or have concerns, don’t hesitate to consult a qualified EV technician for diagnosis and advice. | Early intervention can prevent minor issues from becoming bigger problems. |
| 20 | Stay informed: Keep yourself updated on the latest advancements in EV battery technology and maintenance best practices to optimize your experience. | New technologies and insights emerge continuously, allowing you to adapt your care approach for better results. |
