What is HCA rating?
The full form of HCA is hot cranking amperes. It is the same thing as the MCA or the CA or the CCA, except that the temperature at which the test is conducted is 80°F.
How can a standard automotive or marine battery's state of charger be accurately measured?
The state of charger of a lead acid battery is most accurately determined by measuring the specific gravity of the electrolyte. This is done with a hydrometer. Voltage also indicates the level of charger when measured in an open circuit condition. This should be done with a voltmeter. For an accurate voltage reading, the battery should also be allowed to rest for a period sufficient to let the voltage stabilize.
What Are The Different Types of Rechargeable Battery Chemistries & Technologies?
Batteries in portable consumer devices (laptops and notebooks, camcorders, cellular phones, etc.) are principally made using either Nickel Cadmium (Ni-Cd), Nickel Metal Hydride (Ni-MH) or Lithium Ion (Li-ion) technologies. Each type of rechargeable battery technology has its own unique characteristics.
My new laptop battery is not Charging. What is wrong?
New batteries are shipped in a discharged condition and must be charged before use. We generally recommend an overnight charger (approximately twelve hours). Refer to the user's manual for charging instructions. Rechargeable batteries should be cycled (fully charged and then fully discharged) two to four times initially to allow them to reach their full capacity. (Note: it is normal for a battery to become warm to the touch during charging and discharging).
