Smart battery repair shops use a computer program and a standard 12C parallel port adapter to reset the data in smart batteries’ EEPROM chips. The program can be downloaded from the internet and doesn’t require extensive knowledge of electronics or programming. The program resets the internal battery codes and clock to match the actual battery charge, preventing overcharging or overdischarge. Smart chargers also use the clock, voltage, or temperature to charge batteries, and misalignment can lead to under or overcharging.
A smart battery repair shop typically has a computer program that resets the data contained within a smart battery. The program typically works when used in conjunction with what’s called a standard 12C parallel port adapter, which connects the battery to the computer via an electronic relay. Smart batteries typically contain electrically erasable, programmable, read-only memory (EEPROM) chips that hold battery data. When this data is not synchronized with the actual energy level of the battery, an overcharging or overdischarge may occur. The smart battery workshop fixes these settings.
Different versions of the smart battery workshop are readily available on the internet. Each program’s website generally specifies which devices are compatible with which particular smart battery workshop. The program does not usually require people using the Smart Battery Workshop to have extensive knowledge of electronics or computer programming. People can purchase the appropriate parallel port adapter, download the program, and connect the battery to the computer via the adapter. Users with basic electronics knowledge can build their own parallel port adapter, using inexpensive materials, in less than an hour.
The battery is connected to the adapter, which is connected to the computer. The program is then started. By accessing the program’s EEPROM reset window, the user can choose the reset function, automatically resetting the internal battery codes. The program often contains windows showing bit flags, serial bus data, and EEPROM read/write information.
In addition to containing the negative and positive terminals, the smart battery usually has a data terminal containing the temperature and charge level of the battery. The terminal also contains the clock which monitors elapsed time on a current charge. The clock setting is usually synchronized with the amount of energy stored within the battery. When a smart battery is completely discharged, this internal clock usually resets itself. Misalignment of clock and capacity level can occur when a battery dies during storage or when basic functions operate contrary to a collection of programs running simultaneously, requiring more power.
Smart Battery Workshops reset this watch to match the actual battery charge. Smart chargers, also called smart battery backups, charge batteries by measuring the battery voltage, internal clock, or temperature. If the charger uses an incorrectly programmed clock to determine the amount of charge applied, the battery will typically become under or overcharged.
