12 volt 35 amp batteries contain 12*35=420 watts so 8000 divided by 420 is 19.05 batteries.
How big of a battery do I need car audio?
Can I use an extra battery for car audio?
Adding a second battery is a good idea if you want to be able to run your car audio system longer when the engine is off, but it won’t do you any good when the engine is actually running.
What is the best battery to use for car audio? – Related Questions
What happens if you put a too big battery in a car?
If you use the wrong size battery, this could cause changes in the flow of electrical currents, resulting in power surges that can damage the onboard computers or other components.
What size alternator do I need for 3000 watt amp?
To obtain 3000 Watts AC at 120 Volts from an inverter, you must replace your 100 AMP alternator with an expensive 250 AMP alternator and install MULTIPLE heavy duty batteries. In addition, 50 more amps are required to operate your vehicles accessories, lights, flashers etc.
Can you run two batteries one alternator?
Can you run two batteries one alternator? Yes, as long as the batteries match. Your alternator actually recharges your batteries while your engine is running. If you have 2 batteries connected, and they’re the exact same type, then your alternator will charge both of them.
Can you put an extra battery in any car?
If you think that you could use some extra battery capacity in your car, whether to run a powerful car audio system or anything else, it is possible to install an auxiliary battery in just about any car or truck.
How do I hook up a second battery to my alternator?
What will happen if you add another battery?
The electrical capacity of different types or batches can differ. If such different batteries are used the difference in electrical capacity will grow during usage which could eventually cause one of the batteries to over discharge, leak and even explode.
Will adding a second battery help my audio system?
Having an extra battery will help your system sound better at higher volumes and can dramatically increase the longevity of your amplifiers.
How many 12V batteries can I connect in parallel?
There is no limit to how many batteries you can wire in parallel. The more batteries you add in a parallel circuit, the more capacity and longer runtime you will have available. Keep in mind that the more batteries you have in parallel, the longer it will take to charge the system.
Is it OK to mix battery brands together?
Q: Can you mix different brands of batteries? A: As chemistries and voltage vary across both battery types and brands, we recommend that you do not mix batteries. Mixing of cells can result in battery leakage and sub-optimal device performance.

Frequently Asked Questions.
Can you connect 2 batteries with different amp hours?
You cannot connect batteries of different amp-hours in series with good results. We strongly recommend you DO NOT attempt to mix battery sizes (amp-hours) and connect together. Due to differences in battery management systems and battery cell counts, there may be a charging and voltage discrepancy between batteries.
Can you run different size batteries in parallel?
It’s just fine to put different batteries (capacity) in parallel providing they are the same technology (all lead acid all LiPo all NiCad etc), You don’t need balancing electronics and cannot overcharge a smaller capacity one in parallel with a larger capacity one.
Do you need to balance batteries in parallel?
Balancing is only necessary for packs that contain more than one cell in series. Parallel cells will naturally balance since they are directly connected to each other, but groups of parallel wired cells, wired in series (parallel-series wiring) must be balanced between cell groups.
What happens when 3 batteries are connected in parallel?
When two or more batteries are placed in parallel, the voltage in the circuit is the same as each individual battery. That is two, three, four or more 1.5 volt batteries in parallel will produce a voltage of 1.5 Volts!
Can you charge two 12V batteries in parallel at the same time?
