Owning jumper cables is like owning a truck. When you own a truck, people seem to cozy up to you when they are moving. When you own jumper cables, you're suddenly like Batman but for dead batteries. You might as well give your friends a Jumper Cables Signal that they can point at the cloudy sky in times of crisis. With great power comes great responsibility, I guess. (And now I am mixing metaphors.)
Car batteries are full of toxic chemicals and have to be dealt with specially when they die. The green thing to do is to squeeze as much life out of them as possible and decrease the overall amount of batteries that you are going to need in your lifetime. Here are some tips for that.
A thoroughly insulated garage will keep your battery warm in the winter. Skip heated garages. They will rust your car.
Remove the clamps and clean away grease, dirt and oxidation. A filthy battery connection will weaken the charge.
You can purchase an inexpensive solar charger for your car battery. The charger refills your battery's charge with solar energy. Combo this device with a monitor so you don't overcharge the battery.
If you're stretching the life of a conventional battery, you may have to add some water to it. Here is how this is done.
If your battery is jiggling around, it could tip over. A loose battery bashing against other parts of your engine is bad. Battery acid spilling all over your motor is also bad. Keep the battery tray clean. Make sure the battery sits correctly.
