What happens if you use the wrong size battery?
Manufacturers precisely match their alternators and batteries to the vehicle’s power requirements. A mismatched battery/alternator combo could cause your alternator to overheat and shorten its life.
Can I replace a 12v 7Ah battery with a 12v 9Ah battery?
As the dimensions of the 12 Volt 7Ah battery and the 12 Volt 9Ah battery are exactly the same, they are interchangeable.
Can I replace my laptop battery with a higher mAh?
The battery will only supply as much amperage as the device requires, so a higher mAh rating is not a problem (and indicates longer battery life). What matters here is that the voltage of the battery matches that of the computer. Actually, it indicates capacity, not maximum current.
Is 2Ah better than 5Ah?
So in addition to having double the cells, the 5.0Ah battery also has a higher energy density in each one. In general, higher amp hours mean more runtime and higher voltage means more power.
How do you know what size battery your car needs?
Your car’s battery group size can be found in the battery section of the owner’s manual. If you no longer have access to your original owner’s manual, you may also consult the reference guides provided by battery retailers to determine the appropriate battery group size for your car.
What happens when you change the size of a battery?
Under normal conditions, if you change only the battery capacity and make no other system modifications, it will take the same amount of time to charge both batteries (obviously if resistance is not the same, this will affect charging, regardless of the total capacity of the battery).
What happens when you charge a lower capacity battery?
When you charge the batteries, the reverse happens–the battery with lower capacity will be charged faster, and can be overcharged. You can probably see where this is going–the battery with lower capacity degrades faster, lowering its capacity, which accelerates the process.
Where can I buy a higher capacity battery?
The Batteries are offered on multiple outlets like Ebay.com, Amazon.com and various other online stores. The prices for those batteries are usually 50% higher than for a regular battery. That by itself would not be bad, if those batteries truly have higher capacity storage. No parts specified.
What happens when you mix different types of batteries?
Each battery acts like a resistive load, and current will flow to the battery with the lowest resistance, or highest capacity, more than the rest. All of them will reach the end of bulk charging together, when they’ve all reached the same voltage (remember, they’re connected together–they have no choice!).
