Car batteries are electrical storage units that convert chemical energy to electrical energy. The basics of how a car battery works haven’t really changed much in 70 years. The battery in your car is a lead-acid design; acid, or electrolyte, reacts with the lead plates inside the battery to produce electricity. Not surprisingly it takes more power to turn over a big engine than a small one, so your battery needs to be sized and rated accordingly. Vehicles today also have far more demanding electrical loads from numerous computers, modules, and accessories and will need a battery with enough power for those systems to work properly. Overworking an automotive battery by installing one that's too small to meet all the vehicle's power demands may cause the electrolyte reaction to fail prematurely.

No matter how well you treat your vehicle, car batteries still wear out every few years and need to be replaced. It's just one of those regular maintenance items we deal with as car owners. Luckily, installing a new battery is a straightforward job, and one we'd recommend for all DIYers. Do it yourself in the garage Saturday morning, and have confidence that your vehicle will start Monday morning—and every morning, even in the coldest weather. Here's how to disconnect a car battery and install a new battery.

Each cell in a battery contains a plate group, called element. An element consists of a designed number of positive and negative plates, both plates insulated by the separators. These prevent the plates from touching and causing a short circuit. Separators are a nonconductive, microporous materials that has the function to prevent the short circuit while allowing a good electrolyte diffusion between the plates. The most important property of the separator is the electrical resistance, which is directly related to the cranking capability of the battery. The main factors that determine the separator resistance are the microporosity and the raw materials used in the separator production processes. The polyethylene separator meets the requirements for high microporosity and lower electrical resistance as well, so that for major battery manufacturers it is the best choice to provide high cranking power performance, which is one of the features of the PROBE MF PREMIUM Battery The number of plates in each element determine the battery electrical performance. Increasing the number or size of the plates increases the overall plate surface area, exposes more reactive lead to the electrolyte, increasing the discharge capacity and the electrical current available during a cranking discharge. Each cell , consisting of one element, has an open circuit voltage of about 2,13 volts, and in a 12 volts battery there are six cells connected in series for a total open circuit battery voltage of approximately 12,80 volts. The intercellular connections between the cells are made using through partition connectors, welded by a process called extrusion-fusion process.

A UPS for your computer equipment provides two primary services. It can condition the AC voltage, eliminating or at least vastly reducing surges and noise that can disrupt or damage your computer system. A UPS is also capable of providing your computer system with temporary power when the electrical service to your home or office goes out. In order for a UPS to do its job, it must be properly sized to deliver sufficient power to the devices you have connected. Sizing includes the minimum amount of power needed to run your devices, as well as the length of time you wish to have the UPS battery provide backup power. In order to size a UPS, you need to know the amount of power used by all the devices connected, as well as the amount of time you would like the UPS to be able to provide power to the devices in the event of a power outage. The more devices connected, and the longer you wish to have them be able to run in a power outage, the larger the UPS you need.
