Negative plates in the battery are naturally this dark color. A short between plates causes a discharge or equalization in potential which more or less is changing the positive plates and post to the color of the negative. The battery will become useless.

The red wire goes to the positive battery post and the black wires connect to the negative post. If it will not turn over then possibly the starter is defective.

You connect the cables BEFORE you plug in or turn on the charger. Positive (red) to battery positive first, then negative (black) to battery ground. Then you turn on your charger and set the timer.

What do you charge a lawn mower battery?

Not sure if the question is what to charge the battery with or how to charge the battery. So, I will address both: A regular battery charger can be used. IF you are going to purchase one, you really don't need a top-of-the-line, expensive charger. A simple 2 to 6 amp slow-trickle charger will do the job. To charge the battery, connect the red charger cable to the positive battery post and the black charger cable to the negative battery post, then turn on the charger until the battery is charged. If necessary, clean the battery posts and cables before charging. The battery charger will have more complete details for charging the battery.


How do you identify battery terminals without any marking?

Best way would probably be to use a multimeter or voltmeter. Turn the meter on to volts DC and connect the probes to the battery terminals, if the voltage is shown as a negative, then switch the meter's probes around at the battery end so it shows the voltage as a positive reading on the meter. Mark the positive and negative terminals on the battery after this. Some car batteries have the negative terminal as the small post, but on some as the big post.


My f 150 pickup won't start have replaced battery and starter still wont turn over will start when jumped?

You replaced the battery, is it good?? You really haven't given sufficient info. Check the Battery, Cables, Solenoid, Starter. The way I read this is that you put in a new battery and the truck's engine will not turn over when you turn the key. When you jump the truck, it turns over, starts, and runs. Are you jumping from positive to positive and negative to negative on the batteries OR are you going battery post negative on the vehicle giving the jump to a frame, engine bracket, or body metal point on your F150? If you are going positive to positive/negative to negative on the batteries, then I suspect your new battery. If you are hooking the negative jumper up to a ground other than the negative post on your battery, then I would suspect a bad negative cable. Speaking of cables, did you clean any corrosion off of the terminals when you replaced the battery? Corrosion does funny things. If in doubt, replace the battery cables.
