More info about car battery replacement
Lead-acid batteries are the most common type of battery used in passenger cars and commercial vehicles, and have been used by vehicle manufacturers for decades. They come in various types, the two main ones being calcium/calcium maintenance free batteries and open top maintainable batteries. Both designs are lead-acid batteries and are often interchangeable
Many modern or European car batteries are Absorbent Glass Mat, known as AGM batteries. These batteries are a type of lead-acid battery but use a different electrolyte that is absorbed by a fiberglass mat. They are more expensive but have specific features and characteristics suited to their application. AGM batteries cannot be replaced by alternative types of batteries, such as maintenance free batteries, as the vehicles electrical system is specifically designed to operate with and maintain AGM batteries only.
There are several other types of technologies such as Stop/Start, Hybrid Electric, and Plug in full Electric vehicles that each have specific automotive battery requirements. The Auto Super Shoppes team can provide you with the right advice and quality batteries with manufacturers warranties of up to 40 months to ensure your vehicle operates properly and starts reliably.
It is important to note that car batteries contain hazardous chemicals and should be handled with care.
Frequently Asked Questions about Car Battery Testing and Replacement
How long do car batteries last in New Zealand conditions?
Car batteries typically last 3-5 years in New Zealand. Factors affecting battery life include climate conditions, driving habits (frequent short trips deplete batteries faster), vehicle electrical demands, frequency of servicing and battery quality. Regular testing after the 2-year mark helps prevent unexpected failures.
How can I maximise my car battery life in New Zealand?
Extend your battery life by ensuring regular testing during scheduled services, avoiding leaving lights or accessories on or using your radio when the engine Isn't running. Taking occasional longer drives to fully recharge the battery, keeping terminals clean and protected from corrosion, parking in shaded areas during extreme heat, and using a battery maintainer during extended periods of non-use can help. These simple practices can significantly reduce shortening your car battery's lifespan.
What are the warning signs of a failing car battery?
Watch for slow engine cranking, dimming headlights during starting, illuminated battery warning lights, electrical system glitches, and requiring frequent jump-starts. Other indicators include corroded terminals, a swollen battery case or slower than normal electric window movements. These symptoms suggest your battery requires immediate professional testing before leaving you stranded.
Should I replace my car battery myself or use a professional service?
While DIY battery replacement is possible for some vehicles, professional installation is recommended for most modern cars. Many vehicles require battery registration or coding to the vehicle's computer system after replacement. Professionals also ensure proper terminal connection, prevent electrical system damage, handle old batteries safely, and can identify related charging system issues that might have caused the battery failure.
How much does car battery replacement cost in New Zealand?
Car battery replacement in New Zealand typically costs $300-$650 depending on battery type (standard lead-acid, AGM, or EFB for start-stop systems), capacity requirements, and your specific vehicle model. This price may include professional installation, terminal protection, and environmentally responsible recycling of your old battery. Higher quality batteries usually represent better long-term value.
