Do you have a volt ohms meter? If so you can test the wires and find the correct ones. If not you might want to look at the cord for any sign of polarity, last resort take the cover off the charger and look at the board for the positive terminal going to the cord and trace it out. That is all I can think of to help.

Trying to charge battery for first time. It says connect two red connectors. Do you charge it first then connect the connector afterwards?

1. I assume this is a car battery so the first thing you do is to disconnect the vehicle cables from the battery terminals. The negative first and then the positive. The positive terminal is marked with a plus sign ...+ ... When refitting the cables to the
battery after it is charged you fit the positive cable to the positive battery terminal(+) first and fit the negative(-) last.

2. Now that the battery is unconnected from the vehicle you can fit the charging cables to the battery terminals. The charger you have should have 2 cables leading from it , a positive with a red plastic insulation on the clip and a negative cable probably with black insulation on the clip.The instructions with the charger will tell you in which order the cables are to be attached to the battery and the order you remove them. Each of the 2 cables has to be clipped onto the correct battery terminal. The positive cable(+) from the charger goes to the positive battery terminal (+)and the negative cable(-) from the charger goes to the negative battery terminal(-).

3. Once the cables from the charger are properly connected to the battery, you can plug in the charger and turn on the power.

4. Batteries generate explosive gasses when being charged and it only takes one small spark to ignite them. Don't reconnect the battery after charging for a half hour or so and make sure the area where you are charging is well ventilated.

Car battery is dead. I have a Black and Decker Simple Start car battery recharger. I can figure out how to plug the outlet part into the wall but I do not know what to do about the part that goes onto...

You should have 2 wires with clips = one red that you clip on the Positive [ + ] post of the battery, this may be marked red on the cable. The other black clips to the Negitive [ - ] post of the battery.
Don't plug in the charger untill you clip the wires to the battery, make sure the charger is set to 12 volts. If your cherger has a cigar lighter wire just plug it in to the dash port.

I just purchased a Deltran Battery Tender Junior to charge the weak battery on my motorcycle. I was told to hook it up to the battery of my 2008 Yamaha Royal Star Venture. Butl in reading the directions,...

Jerry ,
An alligator clip is not required . just connect your terminals the right way . The red ( positive ) to the positive + on the battery terminal and the negative to the - of the battery . Please ensure to have the ignition turned off while you are charging the battery of you may " cook " some relay or CDI unit which is the main brain of the ignition system . Make sure to have good contact between the charger and the battery . The best way to recharge a battery is to disconnect the terminals from the bike to the battery and connect the charger alone to the battery to avoid any damage . Best of luck with that

Charging the battery safely

I wish more people would ask this question.First of all get yourself a good charger,one that will do 2 AMPS and up on a positioning switch.Take the positive lead from the charger(RED) and clip it to the postive terminal of the battery,it will be clearly marked with a + sign or the lead will be red as well.Then take the negative clip(black) and attach it to the negative terminal OR a good clean section of the frame.Then turn the charger on/plug it in. When removing the clips remove the negative first and then the positive(this is really important because you don't want to cause a spark). If it is wet damp,or really foggy DO NOT try to charge the battery,I have seem them explode under these conditions.The other alternative is to purchase the type of charger that connects permanently to the battery and all you have to do is plug it in. This is a good option to keep the battery up in cold weather.Hope this helps ,good luck

Need to charge battery on my chevy venture. Please show me how

Okay... One can not see the negative battery terminal so.... Connect the negative clip from your charger to the chassis and then remove the RED plastic cover in front of the black relay box above the battery OR the plastic cover from the positive battery terminal and connect the positive cable. Make sure you have good connections by watching the meter on your charger. Then plug in the charger and turn it on. Charge time depends on the strength of your charger. I'm going to go hook mine up again because I need to go out for a bit. I don't think I'm going to like changing this battery..... Just thought I'd share..... Good luck.

How do I get my battery to recharge?

two things.

you can remove your battery and have it charge somewhere else if you dont have a home charger or if you have a home charger, you can just hook up the red cable to the positive terminal of the battery and the black cable to the negative terminal.

if you have a jumper cable, these cables have a pair of black and red alligator clips, use them to connect another car's battery in parallel to yours.

use a pair in your battery, put the red one in your positive terminal and put the black one in the negative terminal. be careful that the other pair on the other end dose not touch with each other. somebody should be holding them apart.

then o the other end where there is a good battery, start the car , now put the black clip to the negative terminal of the battery and then put the red clip to the positive terminal.
there should be a spark as you put the last red clip so be careful.

let it be for about 15-20 mins. you can rev up the running cars from time to time.

then after 2- min, you can start your car.

you will only fry your computer if there is a wrong lead on a wrong terminal so be very careful in choosing which terminal is positive and which is negative.

the positive terminal is marked with a plus sign "+ "
the negative terminal is marked with a minus sign " - "

tnx 4 using fixya,
