Need a New Car Battery? How to Choose the Right Type

rev up your engines, eventually car batteries go bad, how do you decide how

to buy the right one for your car, now years ago when I was young,

batteries didn't cost much, you could get up for 35 bucks it was no big deal

picking out a battery, but these days it is a pretty big deal, look at the prices,

they're not giving them away, so I'm going to give you a little battery lesson,

when I was a kid, we had batteries naked, they were vacuum sealed, we break the

vacuum seal, then fill them with acid when a customer needed a battery, and

they were vacuum sealed for a reason, they had an indefinite shelf life that

way, today at the factory, they're filled with acid, so they start to deteriorate

the minute they're built and the acid is put in, now filling the batteries with acid

at the factory is not a good idea because they start to deteriorate, and in

this case, if you look closely, you can see this one is made in Korea, so filled it

with acid in Korea, then they ship it on a boat here to the United States,

it can take a long time between it being made and you actually install it in your

car, I've seen that particular brand of battery

sometimes they last a year or two and that's it, because of this, in a sense

batteries are kind of like eggs, now all batteries are dated, this is an

easy one to read, it just says 8/13, so it was made 8 of 13, so when you're

buying a battery, look at the date and don't buy one that's more than one or

two months old, because it's deteriorated, so you want to buy your batteries from

the place that sells a lot of batteries, now don't be fooled by some of these chain

stores, where they have a pyramid of batteries sitting there, some of those

batteries are in that pyramid for months, and they're not going to last long, so

always check the date of your battery, then comes the question, should you buy a

battery that has a removable top where you can add battery water, or should get

a sealed one that you can't add battery water too, now this decision depends on

you, because if you're the type of person that's never going to check the battery

water, buy one of the sealed batteries, of course they're not perfectly sealed, they

still have vents to vent some gas, but the smaller vents, so they'll lose water

a lot slower than a non sealed battery, but

they will eventually run out of battery acid inside, then you got to replace the

battery, the open style batteries, they got tops you can take off, and you can look

inside and check the water level, so if you're diligent like me, you can add

distilled water when it gets low, and these batteries will actually last

longer, but if you aren't diligent, they'll last a shorter time, so that

depends on you, whether you're going to check the water or not, now there are

other types of batteries out there you can use it lasts a really long time, like

I have in my motorcycle here, it has a lithium iron battery, not lithium-ion but

lithium iron phosphate, now it's an entirely

electronic battery, with no acid in it at all, and it's about 100 bucks and it

works great in a motorcycle, but due to manufacturing process and economy of

scale, the ones for cars cost a whole bunch of money and generally only racers

use them, because here's a lithium iron phosphate battery for a car, and it

starts at six hundred and twenty dollars, so odds are you're going to be buying a

conventional battery for your vehicle, but if your vehicle comes with a more

modern battery like this absorbed glass mat battery, it is a good idea to still

use an absorbed glass mat battery when it's time to replace it, because your

charging system was designed for such a battery, these batteries do cost a little

bit more, but they still have acid in them and the same rules for buying them

applies as with regular water acid batteries, so the next time your car

battery goes bad, you know how to replace it, more quick fixes on the Scotty Kilmer
