### How to wire rhe batterys for 24 volts... Example pos. To pos. Or neg. To pos. Ther are two batterys 12 volts

if you want the same voltage but with increased capacity connect positive to positive and negative to negative on each successive battery ---connected in parallel
example 6 X 12 batteries each of 200 crank hours will be equal to 12 volts and 1200 crank hours ( good for mobile fridges , winches , battery hoists etc)
if you want to increase voltage in the bank then connect positive to negative for each successive battery ---connected in series
for example
with 6 X 12 batteries of 200 crank amps you will have 6 times the 12 volts which equals 72 volts and the current flow is increase from 200 crank amps to exceed the 1200 crank amps because of the electrical principles and formula I think it works out to be around 72 times the 200 crank amps ( I am sure that there are mathematicians out there that will adjust the sum to make it correct)
However I think that you get the idea
when charging batteries it is always positive to positive with the battery leads to the first battery in the bank and the difference is if in parallel the charger has to be big enough the charge at the accepted rate of the batteries ( 12 volts charge at 14.5 volts and around 20 amps an drop back as the batteries charge
when the batteries are in series it all changes and best talk with a good battery supplier as to how it is set up and if you need to change the charging circuit and equipment

### How can i hook up a car stereo in the garage without using a car battery, and get the same juice as far as wattage and power???

Wire a 12 volt AC adapter to it. Connect the power to the positive wire, & the ground to the negative wire. If it's a low power unit a 1 amp adapter will work. If it's a high powered unit you might need a 12 volt 5-10 amp adapter designed for monitors, TVs, monitors, & some laptops. Beware some laptop AC adapters can be 16-36 volts. Make sure you use a 12 volt one, & know which wire is positive, or you'll burn it out.

### How do u charge a edelbrock power wheel corvette for kids 12 volt batteries and a 6 volt charger

Hello! Due to Charger Voltage Compatibility: Never use a battery charger unless the battery voltage matches the output voltage rating of the charger...Therefore do not use a 6-volt charger on a 12-volt battery and visa-versa...

### Need to purchase a battery charger, what type do you recommend?

It really depends on what you are going to use it for. I use a small charger when I just want to maintain a battery. I use mine also for keeping the battery up while I am performing computer diagnostics on a vehicle without the engine running.
The charger I use is a DSR Pro Series Model PSC 12500A It is fully automatic and has a 125 Amp boost. It is very compact and easy to use. It has LED's that tell you the condition of your battery, the charging rate, etc.
I purchased mine from Matco Tools (Matco part number MIC1200) It is available through many local parts suppliers as well as online automotive parts and equipment suppliers.

### I inherited the charger w/no manual - as I've

I can find no manual on line for the charger but the basic & most important things I can share with you.

On the charger should be your On & Off switch, possibly 6 volts / 12 volts switch, (you want 12 Volt) some have a meter to show how much amp draw is taking place as it is charging and you'll have to determine that from observation.

MOST important parts: It is best to disconnect the battery you are charging, at least the Negative post. This will speed up the charge process & prevent any mishaps with the electrical system on the vehicle. I prefer the battery completely removed & placed on an insulated material, plastic, wood, rubber, to prevent battery drain by sitting on concrete or the ground.

If you can check the battery first for swelling/cracked case=don't charge! Frozen inside=don't charge! Thaw first. The fumes from batteries charging are explosive & no sparks, or flames should be anywhere near. Upon reinstalling, Negative wire is always last to connect & be sure that everything inside as far as lights & ignition switch are off to prevent excessive sparking when you connect the final cable.

Charging & connecting. I prefer to test unknowns such as the connecting cables to make sure they are what they say they are. You need a multimeter for this but for now, I am expecting they are marked properly for this instruction. You need a Positive clamp , this one usually has Red handles, to connect to the Positive terminal of the battery (marked POS or +) The other cable, generally Black, connects to the Negative terminal (marked NEG or - ) and provides the ground to complete the circuit.

Make sure connections from the charger to the battery are all clean & well attached, then turn ON the charger. This will prevent sparks near the battery. Be sure to turn off the charger once charging is completed, then disconnect the cables from the battery. The unit you are charging with should give you some indication about when you're charged 100%, but these are the basics of charging a low battery. If by chance your charger shuts down on you & stops charging immediately, you either have the terminals reversed, or a shorted battery. good luck

### Battery in Jeep Grand Cherokee dead this am and less than 1 year old. I have a Everstart 100 battery charger plugged in and on the car. How long does it take to charge the battery. The charger is plugged...

How many amps does this charger put out????
A small trickle charger will take forever to fully recharge a dead battery, you'll need to have a battery charger that can put out enough amps to properly charge a dead battery.To clarify, the chargers sold at Sears, the large square types on wheels are the best for charging dead batteries and they also have an amp meter telling you how much the battery is accepting. After you charge your battery, you should be around 12.5 volts to 12.7 volts. DO NOT OVER CHARGE!!!

### Meter Explanation

You are correct on all accounts. A high number means you dying battery is sucking more juice from the Schumacker. A low number means the battery is not as thirsty. That's how I always think of how to read the meter on mine. Slow charge is a better, deeper charge. The quick charge will get you going, but you should maybe follow it up using the normal mode - car alternator and prolonged drive time. I never use quick charge, personally.

### Battery charger on 2008 Chevrolet Equinox

most chargers have a few different settings you want to put it ona slow charge for about 4-6 hrs bye slow charge I mean it should have a 2amp or a3amp trickle charge unless you are attempting to start the car immeditly the you will you the setting labled starting
