Many EV owners worry about their 12V battery's life. Electric car 12V batteries use lithium-ion, which last longer than standard batteries. This post looks at what affects the average life of a 12-volt car battery.

Find out how to extend your battery’s lifespan.

The lifespan of 12V Batteries in EVs

12V batteries in electric vehicles typically last between four to six years. They generally outlive standard car batteries, which usually need replacing every three to five years.

Typical lifespan of EV batteries

EV batteries last between 15 and 20 years and can run for 100,000 to 200,000 miles, which is longer than the lifespan of standard car batteries.

When compared to standard car batteries, EV 12V batteries offer several advantages. We are listing them below.

Factors Affecting 12V Battery Lifespan

Several elements influence the lifespan of a 12V battery in EVs. Understanding these factors can help maintain and extend battery performance.

Heat and Air Conditioning (AC) Usage

In cold weather, heat pumps use between 1 kW and 5 kW. This power comes from the 12V battery for electric cars. The HVAC fan also draws energy from the battery. High usage can shorten the life of a 12V battery.

Advanced Driver Assistance Systems (ADAS)

Advanced Driver Assistance Systems (ADAS) use power from the electric car 12v battery. Features like lane assist and automatic braking each draw a small amount of energy. Together, they can shorten how long a 12v battery lasts in EVs.

Each ADAS component adds to the strain on the battery. Over time, this cumulative energy use impacts the average life of a 12-volt car battery. Vehicle owners should be aware of how ADAS affects their battery’s lifespan.

Type of Battery

Li-Ion 12V batteries can last a lifetime under normal conditions. AGM batteries typically last six to eight years and are used regularly. SLA batteries reach close to six years, while standard car batteries usually last three to five years.

These differences affect how long does a 12v battery last and what is the average life of a 12-volt car battery. Selecting the right battery type is essential for maintaining overall battery health.

Driving with Low Traction Battery Charge

Driving with low traction battery charge harms the 12V battery quickly. Systems stop using energy when the traction charge drops below 20-30%. This protection helps, but frequent low charges wear the battery down faster.

Deep cycle 12V batteries handle deeper discharges better. Fully charging a 12V battery usually takes around 4-6 hours with a standard charger.

Long-term Effects of HVAC and ADAS on 12V Battery

HVAC and ADAS have a minor impact on the 12V battery but greatly improve comfort and safety—read on to find out more.

Minimal impact on battery lifespan

Using the HVAC system barely affects the 12V battery's lifespan. ADAS features also have little long-term impact. Modern EV batteries manage the power needs of these systems efficiently.

This ensures vehicle owners enjoy comfort and safety without frequent battery replacements. Recent 12-volt battery news highlights improvements that keep battery wear to a minimum.

Benefits in comfort and safety

HVAC systems provide significant comfort benefits by keeping the cabin at the right temperature. ADAS systems offer major safety advantages, helping drivers avoid accidents. Knowing how long a 12V battery takes to charge ensures these features work reliably.

Optimising 12V Battery Lifespan

Keep your traction battery charged and regularly check your 12V battery to prolong its lifespan – read on to find out how.

Importance of maintaining traction battery charge

Maintaining the traction battery charge above 30% is crucial for the 12V battery's health. This practice prevents excessive strain and extends the battery's lifespan. Deep cycle batteries support over 5,000 discharge and recharge cycles, enhancing durability.

Knowing how long does a 12v battery take to charge helps manage energy use effectively.

Regular battery condition checks

Use tools like the MVT handheld tester to check your battery regularly. These tests are the same as those for standard car batteries.

Frequent testing finds problems early. Keeping the battery healthy extends its life and ensures it works well.

Conclusion

Lithium-ion 12V batteries in EVs usually last longer than standard car batteries. High temperatures and frequent AC use can reduce battery life. Keep your traction battery above 30% to protect the 12V battery.

Regularly check your battery’s condition for optimal performance. Proper maintenance ensures your EV’s 12V battery remains reliable.
