Keeping your battery healthy isn’t just about avoiding a dead start. It’s about long-term performance, reliability, and cost savings.
Whether you’re driving an electric vehicle or a gas-powered truck, knowing how to extend car battery life can save you from early replacements and unexpected breakdowns.
Let’s break down the best tips for both battery types and what to watch for.
EV Battery Care Tips
Electric vehicle batteries can last a decade or more if you treat them right. Here’s how to keep your EV battery healthy:
1. Stay Between 20% and 80% Charge
Charging your EV to full capacity every night might feel safe, but it’s not ideal. Keeping the charge level between 20% and 80% helps reduce stress on the battery and slows long-term degradation.
Pro Tip: Most EVs let you set charge limits in the app or infotainment system—use this feature to automate smart charging habits.
2. Limit Fast Charging
DC fast charging is great for road trips, but overusing it can generate excess heat and wear down battery cells over time. Use Level 2 home charging for daily top-ups and preserve battery health.
3. Watch Out for Temperature Swings
Battery performance suffers in extreme heat and cold. Park in a shaded area during hot months, and precondition the cabin while plugged in during winter to protect your range and internal battery chemistry.

Gas Car Battery Maintenance Tips
Internal combustion engine (ICE) vehicles use 12-volt lead-acid batteries that need regular check-ins—especially in changing weather.
1. Drive Often or Use a Smart Charger
Letting your vehicle sit unused for long periods leads to battery drain and sulfation. Take it for a weekly drive or hook up a smart maintainer to keep voltage stable and extend battery life.
2. Check Terminals and Mounts
Corroded terminals or a loose battery bracket can cause voltage drops and internal damage. Inspect connections monthly, clean any buildup, and tighten hardware to reduce vibration and ensure a strong electrical connection.
3. Be Winter-Ready
Cold temperatures slow battery chemical reactions, making it harder to start your engine. Use an insulation blanket or park in a garage to protect against freezing temps and prevent mid-winter no-start surprises.
4. Know the Warning Signs
Dim lights, slow cranking, or a bloated battery case? These are early red flags. Recognizing why car batteries fail before they do can save you a tow truck bill.
According to the American Automobile Association (AAA), most car batteries last 3 to 5 years, but only with good habits.
EV vs. Gas: Same Goal, Different Approach
While EV and gas car batteries operate differently, smart battery charging habits and temperature awareness go a long way for both.
| Feature | EV Battery | ICE Battery |
|---|---|---|
| Charging | Level 2 preferred, avoid 100% daily | Drive often or use a trickle charger |
| Temperature | Avoid extremes, precondition battery | Insulate in winter |
| Lifespan Tips | Keep SOC 20–80%, limit fast charging | Clean terminals, avoid deep drains |
Build the Habit
Taking care of your battery doesn’t require much, just steady habits. Whether you’re checking EV charge limits or cleaning corrosion off gas battery terminals, a little effort goes a long way.
With consistent care, you’ll avoid costly breakdowns and extend the life of your vehicle’s power system, no matter the drivetrain. Simple steps today can save you serious trouble tomorrow.
