What are the blue crystals on a car battery?
Corrosion from the sulfuric acid. The electrolyte (water) inside the battery is a mixture of sulfuric acid and water. Those blue crystals is just corrosion. You need to clean it off. Remove the negative black (-) cable first and then the positive red (+) cable. With a mixture of 25% baking soda and water, clean all this corrosion off the battery and the cables. You can also use vinegar. Dry everything off and then clean the connections with a battery post wire brush you can buy at any parts store. Reconnect the battery cable positive first then negative.
How to Positive battery terminal replace 05 Acura TL?
Getting a factory terminal is likely not worth it. First make sure the battery cable has enough slack to cut off the terminal, shave back the insulation and use a new terminal. If you don't have enough slack, you'll need to replace the entire cable. If you have enough, remove the battery to save yourself from accidentally grounding/shorting our the battery. Remove the negative battery cable, then remove the positive. Remove the battery. Cut the battery cable where the terminal is. Strip about an inch of insulation. For my 2003 TL, I had to use the truck size terminal from Autozone as the normal one would not fit the 2 battery cables. Truck size = $3.50, car size = $2.99, not a big difference. Make sure the cable is free of corrosion. If there is any of the powder blue dust, clean it all out with a wire brush. Get the battery cable into the new terminal and tighten. Use electrical tape to cover any excess uncovered battery cable. Pop the battery back in, install the positive terminal then the negative terminal.

How do you jump a 2006 Honda Shadow Aero battery?
The procedure is basically the same for cars and motorcycles, the brand does not matter. First, make sure the bike ignition is switched off. Next, locate the bike's battery. This is under the seat. You can use a car battery or another fully charged motorcycle battery for jumping but first you should ask yourself a question: why is the bike battery without power? If the battery is old, then there is no option but changing it as jumping is an emergency procedure, not a permanent solution. Next, get jumper cables. Connect the red cables to the positive poles and then connect the black or blue cables to the negative poles. Always connect to the jumper battery before connecting to the bike battery. Now, leave the cables in place for a minute or two, then try starting the bike. You will normally be able to start the engine soon unless there is a mechanical or other problem preventing its start. As soon as the bike engine starts, disconnect the jumper cables, beginning with the negative cable at the bike battery, then the positive cable. Be careful, it is normal for some sparks to fly, keep gasoline and other flammable materials away from the place at a safe distance.
