Automotive Batteries
Think of the battery as the heart of your car. You need a battery you can count on to get your motor running and keep it pumping all day long.

The Most Common Chemistries Used in Laptop Batteries
The most common chemistries used in laptop batteries are: NiCad (Nickel Cadmium) - This is the oldest technology and is the least commonly used nowadays. NiCad batteries are prone to the "Memory effect" and are heavier than the newer technologies. NiCad is not environmentally friendly chemistry as it contains heavy metals, which cannot be disposed of in landfill sites. Most manufacturers have stopped producing batteries of this type chemistry. As an end user it will be increasingly difficult to source these batteries. The best alternative is external battery packs. This is an external battery, with run times of up-to 10hours and is compatible with most manufacturers.

Why You Need a Battery Isolator
Cars fitted with bigger stereo needs an alternative power source as they can't rely entirely on the single battery to which they are connected If we have an habit of listening to music when the car ignition is off the consequence will directly lead to complete drain of the primary battery source which results in problem with starting engine, the battery won't have sufficient energy to crank the engine
