is it important that i use the same brand battery that came with the car( Volkswagen-Audi) . Should i use the dealer for purchase and installation of the battery?

My car has 38000 miles.
My car has an automatic transmission.

Experienced mechanics share their insights in answering this question :
It is not necessary to use the exact same brand of battery that the vehicle came with from the factory. Although, it is designed specifically for your car it is not required in order for the car to function properly. The important thing is to be sure that your battery has the proper specifications when replacing it. Many after market (non-dealer) companies manufacture batteries that will suit your car properly. I would recommend having an expert from YourMechanic come to your location to replace your battery.

Battery models have become an indispensable tool for the design of battery-powered systems. Their uses include battery characterization, state-of-charge (SOC) and state-of-health (SOH) estimation, algorithm development, system-level optimization, and real-time simulation for battery management system design.
If the battery is disconnected while the ignition is on, it can set a fault code for the airbag system and turn on the airbag warning light (which deactivates the airbag system until the fault is cleared with a scan tool).
Indications for Battery Replacement

For an Audi car, the lifespan ranges from five to eight years, but there may be several external factors that can cause damage to the car battery and might demand repair or complete replacement.

The H6 and H7 are essentially interchangeable. These are the most common batteries in modern cars and fit most every European cars as well as many of the more modern American cars.
The power and longevity of a battery is noted by its Amp Hour (Ah) rating. Basically, this denotes how long a battery will last if it isn`t recharged. For example if a battery is rated as, say 8Ah, it will be able to provide 4 amps for 2 hours. If a battery is rated as 100Ah, it will produce 100 Amps for 1 hour.
Lithium, an exceptionally light metal, gives lithium batteries the highest energy density of any battery cell. Thus, they can store more energy than alkaline batteries or any single-use battery of a comparable size. And they are superb performers in extreme temperatures, both hot and cold.

in my car battery warning light appearing while driving.so I have replaced both battery and alternater still light is on
ANSWER : As you may yourself have seen, there are many reports of this fault with the Civic, that is a battery or alternator is replaced only to have the warning light fail to extinguish despite checking every conceivable electrical possibility. Your only recourse is to have a certified mechanic go through that exercise with your car and that involves first attempting to "re-set" the light. If the warning light returns, the alternator output has to be carefully measured both loaded and unloaded. All terminal connections have to be verified including all grounds. Fuses have to be checked for integrity (continuity) and the possibility of shorts, in for example dash wiring, has to be checked. To request this repair, simply request an electrical components diagnostic and the responding certified mechanic will seek a resolution to this.

Car battery light is on replaced alternator battery and starter and battery light is still on.
ANSWER : You may have a failing voltage regulator that could be allowing the alternator to supply too much or too little amperage to the battery resulting in the battery never maintaining a consistent charge as it is designed to. The voltage regulator is a unit that regulates the charging of the battery by the alternator. When the voltage regulator is not working properly, this may result in the alternator allowing too much power to be delivered to the battery resulting in damaging wires and prematurely sometimes destroying the battery. A common sign of this is usually the acid inside the battery boiling causing the battery to swell. You may also smell a bit of smoke due to things potentially getting too hot. In other cases it may result in the alternator not supplying enough power to the battery, resulting in undercharging the battery or not charging it at all. I would recommend having an expert from YourMechanic come to your location to diagnose your vehicle’s charging system.

Battery light stays on and overnight battery drain. 2006 Land Rover LR3
ANSWER : Hello – this problem can be diagnosed by connecting an ammeter to the positive (red) battery cable, observe the current drain (likely less than 1 amp), then, one at a time, remove each fuse, check to see if the current drain has dropped to near 0, then reinsert the fuse. This process should identify the faulty circuit in most cases. The specific components on that circuit can then be checked for current drain problems. A professional mechanic, like YourMechanic, can come to your location, and perform this procedure for you, and identify, replace or repair the failing component.

My car is behaving strangely after replacing the battery
ANSWER : Taking off the battery cable while the car is running is not a good test of the charging system. In fact, if you do that to a modern car it’s possible to do some serious damage to your alternator and the control modules in your car.. Taking off the battery cable to test the charging system is an old carryover method that dates back to the 1960’s when cars were equipped with DC generators and had no computer systems. That being said, you may never know if you have done any damage until later on down the road when some of the car’s modules start behaving strangely. I would normally expect to see a check engine light after that has been done. Since you didn’t report one, I wonder if the check engine light is working.
If you replaced the battery without having anything on the system to maintain power, there are a number of settings on the car that will have to be re-learned. Many of them will take care of themselves after a period of driving. But if you have persistent problems, you may have to use a few re-learn procedures: procedures that are a little too involved to talk about here. A code read should reveal if any of these settings are a problem.
The noise you have in your engine is a little worrying. Even though you used low-octane gasoline, your car should still run OK except for some spark knock under load. Most of the time you should notice no difference at all. There is a knock control system on your car that should be able to manage the spark knock and I think there might be a problem there. That and the difficulty starting are going to take some diagnostic work.
I expect there are a handful of trouble codes stacked up in the car’s memories. Some will be from the battery change, some will be from the cable being removed, and there may be some there from a previous fault. If you contact Your Mechanic, They can send a technician to your home or office to read the codes on your car and tell you what needs to be done to sort things out.

Battery drain.
ANSWER : This suggests you may have an alternator that is not working properly. As you may know, the alternator is responsible for keeping the battery charged properly. There is also a unit called a voltage regulator that regulates the charging of the battery by the alternator. Either of these two components, when not working properly may cause the battery to be drained prematurely as you describe. I would recommend having a professional from YourMechanic come to your location to diagnose and inspect your charging system.

Battery light stays on and overnight battery drain. 2006 Land Rover LR3
ANSWER : Hi there – yes, something is going on here that’s draining your battery. Perhaps the pressure of the engine wash dislodged wiring which has shorted, or there was a chemical reaction to the cleaning solution that caused electrical damage in the alternator or voltage regulator. These componnents can be checked off of the vehicle. Vehicle wiring can be diagnosed by connecting an ammeter to the positive (red) battery cable, observe the current drain (likely less than 1 amp), then, one at a time, remove each fuse, check to see if the current drain has dropped to near 0, then reinsert the fuse. This process should identify the faulty circuit in most cases. The specific components on that circuit can then be checked for current drain problems.
