BYD Car Battery Replacement in Singapore
Your BYD’s 12V auxiliary battery, not the main EV battery, still needs replacing like any car.
AAP brings the correct battery to you, onsite, anywhere in Singapore.
Rent from S$80 deposit (refundable) or buy from S$160, onsite fitting + 1-year warranty
Like almost all electric vehicles, BYD models including the Atto 3, e6, and Dolphin run on two separate batteries: a large high-voltage pack that drives the car, and a small 12V auxiliary battery that powers the lights, infotainment, and onboard computers, similar to a conventional car battery. AAP replaces this 12V battery, matched to your model’s exact group size, fitted from AKIRO or DELKOR, onsite, anywhere in Singapore.

Why Does an Electric BYD Still Need a 12V Battery?
Even though the Atto 3, e6, and Dolphin are fully electric, they still carry a small 12V lead-acid style battery separate from the main drive battery. This 12V battery wakes up the car’s computer systems, powers the lights and infotainment, and is what actually lets the high-voltage system switch on when you press start. If it goes flat, the car won’t power up at all, even with a fully charged main battery.
Singapore’s heat and humidity affect this 12V battery the same way they affect a conventional car’s battery. Frequent short trips, long parking spells in the sun, and constant background power draw from the car’s electronics all shorten its working life. A correctly fitted AKIRO battery has lasted up to 2 full years in real customer cars before showing signs of wear.
Do You Need Battery Registration After a BYD 12V Battery Change?
Most BYD models do not require any coding or registration after the 12V auxiliary battery is replaced, the vehicle’s systems recognise it once connected. We confirm this against your specific model and year before we arrive.
The main thing to get right with a BYD is matching the correct 12V battery group size and terminal layout to your exact model, since this is separate from anything related to the main EV battery pack or charging system. AAP confirms this against your model before arriving, so the fitting is a single onsite visit with no surprises.
AKIRO: A Strong Option for Your BYD
For BYD models, AAP offers AKIRO’s standard and EFB 12V batteries alongside DELKOR. AKIRO is engineered specifically for tropical climates, which matters in Singapore where heat and humidity are the main reasons batteries fail early, often well before the rated lifespan of a generic import battery. It is fitted to the correct specification for your BYD model and comes with the same warranty as any other brand we carry.
AKIRO is also AAP’s exclusive battery line in Singapore, so you won’t find it through a dealer or workshop elsewhere. If you’d like AKIRO specifically for your BYD, just mention it when you call and we’ll confirm availability and pricing for your model.
Frequently Asked Questions for BYD Battery Replacement
Answered directly by Bobby Ng, AAP Lead Mechanic
Is this the main EV battery, or something else? +
This is the small 12V auxiliary battery, not the main high-voltage battery pack that drives the car. It powers the lights, infotainment, and onboard computers, and is what lets the high-voltage system switch on when you press start. We do not service the main EV drive battery.
Does my BYD need any coding or registration after a 12V battery replacement? +
No, most BYD models do not require any coding or registration step after the 12V battery is changed. The vehicle’s systems recognise the new battery automatically once it’s connected.
How long does a BYD’s 12V battery last in Singapore? +
Most 12V batteries in electric vehicles last around 1.5 to 2.5 years in Singapore’s climate with normal use, similar to a conventional car battery. We’ve seen correctly fitted AKIRO batteries last close to 2 years on real customer cars. Watch for the car being slow to power on, or dashboard warnings, as early signs of a weakening 12V battery.
Do you come to my location for BYD battery replacement, or do I need to visit a workshop? +
We come to you, anywhere in Singapore, including home, office, or car park. Our mobile units carry the correct 12V battery stock for common BYD models, so the job is completed onsite in one visit, usually within 30 to 40 minutes.
Is AKIRO a good battery for my BYD? +
Yes. AKIRO makes a genuine standard and EFB 12V battery range fitted to the correct specification for your BYD model. It’s engineered for tropical climates, which is a real advantage in Singapore’s heat, and comes with the same warranty as any other brand we fit. AKIRO is exclusive to AAP, so it isn’t available through dealers or other workshops.
Can I rent a 12V battery for my BYD instead of buying one? +
Yes. Every BYD model we service, including the Atto 3 and e6, is covered under the AKIRO Rent-A-Car-Battery programme, where you pay a refundable deposit of half the purchase price plus a flat S$30 onsite fee, instead of buying outright. Return the battery anytime for a full deposit refund.
