HOW TO RECHARGE YOUR CAR BATTERY

customer questions and concerns so I

just might pick yours quick tip on

battery chargers before we get started

now at the shop we use a big old bulky

bulletproof bomb-proof roll-around

charger it's awesome it's old-school it

works great for the home DIY or though I

recommend a microprocessor controlled

charge now this charger was 89 bucks at

O'Reilly's and you can get them for as

low as 59 dollars and what that means is

it's going to give you a safer quicker

more effective charge because most of

them have protection built in that keep

them from overcharging while maintaining

the charge this charger has a percentage

feature that shows you the percentage of

the charge so you can monitor the

progress it also has a voltage feature I

am in no way affiliated with this

charger I'm just a fan so let's go ahead

and get started let's hook up red to

positive black to negative okay let's go

ahead and set this thing up for charging

the first thing we're going to do is

choose our battery type now keep in mind

a lot of chargers won't have this

feature if you've got an older or you

know more basic charger you may not have

this feature but if you do you're gonna

have three choices standard AGM or gel

type battery nine times out of 10 you're

gonna choose the standard battery

feature that is what is in your daily

driver vehicle

a GM and gel batteries are for

high-performance and marine applications

and deep discharge applications such as

those used in trolling motors and

watercraft so we've got the standard

selected next thing we're going to do is

select our rate of charge how intensely

we want to charge the battery now you've

got an 85 amp engine start feature here

and most Chargers will have this feature

this is for jump-starting this is not

for charging keep that in mind you've

got a 30 amp boost feature now this

feature right here you can charge the

battery with it but you don't want to

charge it for too long because if you're

not careful and if you're not monitoring

the battery you can toast the battery if

you just want to throw it on for a

couple hours and give it a quick charge

you can get away with a 30 amp but the

safest and fastest and most effective

way to charge a battery is with the

lowest setting and here it's a two amp

setting now it may take a little longer

it may even take overnight but as I said

it's the safest and most effective way

to charge the battery so we're gonna go

ahead and select that as you can see the

charging icon lit up and we're good to

go now this charger it has a cool

function that shows you when the battery

is completely charged in maintaining

this will illuminate green now in the

case that your charger does not have

this function in a second I'm going to

show you how to tell if the battery is

fully charged after letting your charge

overnight we come back and the battery

is fully charged the green icon tells me

so I also know because the voltage

percentage shows one hundo the voltage

shows 12 and it's ready so if your

battery charger doesn't have a function

on it that shows you when the battery is

fully charged and ready to go and you

don't have a battery tester like this to

check it with all you have to do is

check the voltage periodically

throughout the charging process with a

multimeter the magic number is twelve

point four to twelve point six volts a

fully charged battery sits between that

range twelve point four to twelve point

six so if you hook

and you know let it charge for four

hours and come back and check the

voltage and it's at eleven point eight

volts well you know you still got some

charging left to do to get it in that

magic range it's not perfect but it will

get you in the ballpark and that's it

too easy right guys

super simple stuff or at least I hope

it's super simple now I hope you

understand how to properly recharge a

battery and what some of the options are

in battery chargers nowadays that can

make that process a lot easier for you
