🧊 Best Practices to Maximise Your EV Battery Life

Electric vehicle batteries are built to last — but how you charge, drive, and store your EV can dramatically affect lifespan and performance. Whether you own a Nissan Leaf, Tesla Model Y, or MG4, these tips will help protect your battery investment and maintain range over time.

🔋 1. Keep Charge Between 20% and 80%

For daily use, avoid charging to 100% or letting your battery dip below 10–20%. Most EV battery chemistries are sensitive to extreme charge levels. Keeping your battery in the 20–80% sweet spot reduces stress on the lithium-ion cells and helps prevent long-term degradation.

⚡ 2. Avoid Frequent DC Fast Charging

DC rapid chargers are great for long trips, but repeated high-voltage fast charging can heat and wear the cells. For everyday charging, use AC home or public charging at slower speeds. Fast charging every now and then is fine — just don’t make it a daily habit.

🌤️ 3. Park in Moderate Temperatures

High heat and freezing cold affect battery life. Try to park in shaded areas during summer or in a garage during winter. Excess heat can speed up cell ageing, while extreme cold can limit battery performance. Thermal stability is key to long-term health.

🦶 4. Drive Smoothly and Use Regenerative Braking

Avoid aggressive acceleration and heavy braking. Smooth, consistent driving reduces load on the battery and motor. Use regen braking whenever possible to recover energy and reduce brake wear — it’s more efficient and helps extend range naturally.

💻 5. Keep Software Updated for BMS Optimisation

EV manufacturers constantly update their software to improve Battery Management System (BMS) performance. These updates may balance cell voltages better, optimise charging algorithms, or unlock improved efficiency. Make sure your vehicle gets all available updates regularly.
