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.

Can you boost off a 99 crown victoria battery

Yes, you can. Be advised to hook the positive cable to the positive posts first ( + ) on both batteries, then the negative cable to the "good" battery negative post ( - ) next, then to the "bad" battery's negative post.
It is preferable to do the last step hookup to the engine block (or somewhere else that is steel) than the bad battery to prevent a spark which very rarely can make an explosion.
Also remember. Your alternator is not a battery charger. Therefore, if and when you decide to "boost" someone else off, after you hook up the cables you may well need to have your car engine running about 1,500 RPM and leave the cables to the "bad" battery on for about 5 minutes.

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.
