What Type Of Battery Is Compatible With A BYD Atto 3?

The BYD Atto 3 uses a 12V lead-acid battery to power its electrical systems. Consistent with most EVs, the Atto 3 requires a 12V battery to power low-voltage system functions, which include onboard electronics, lighting, control modules, and the startup process that allows the car to start and operate properly. 

When choosing a car battery replacement, Atto 3 owners should look for batteries that match the correct size, minimum capacity of 35-45 Ah, and matching terminal posts. A lot of batteries may look similar at first glance, but small differences in size or terminal layout can affect the fitment and performance. 

How Much Does A BYD Atto 3 Battery Cost?

The cost of a compatible battery for the BYD Atto 3 ranges from $160 to $175. At Every Battery, we have a wide range of batteries compatible with EV cars to choose from. For the BYD Atto 3, we recommend the Century Lead-Acid Battery NS40ZLB or the Amaron Lead-Acid Battery BH50B20L, both priced under $200.

Why Does A BYD Atto 3 Still Need A 12V Lead-Acid Battery?

As with most EVs, the BYD Atto 3 relies on a 12V battery for the onboard electronics system, separate from the main BYD Blade Battery that powers the electric motor. The 12V battery is used to power systems such as the door locks, infotainment system, lights, safety controls, and vehicle startup functions.

If this battery becomes weak or flat, your car might not power up properly, even if the main battery still has charge. This is one of the reasons why EV battery issues can be difficult to diagnose without professional assistance. Even if your car still has plenty of driving range left, a weak 12V battery might prevent your car from functioning properly. 

How Can I Tell If My BYD Atto 3 Needs A Battery Replacement?

A weak battery on your Atto 3 might not show the same warning signs as a petrol car. Instead of a slow engine cranking that you might expect from petrol or diesel-powered cars, you may notice warning messages appearing on your driver’s display, issues with unlocking the car, or if the car isn’t powering up as expected.

The best way to know for sure is to have a professional test your battery. At Every Battery, our team can check the condition of your Atto 3 battery and determine whether it needs a replacement or if it simply needs a recharge.
