How long will my battery last?
The lifespan of a battery will vary considerably with how it is used, how it is maintained and charged, temperature, and other factors.
What are the advantages of the AGM battery?
The advantages of AGM batteries are no maintenance, sealed against fumes, hydrogen, leakage, or non-spilling even if they are broken, and can survive most freezes. AGM batteries are "recombinant" which means the Oxygen and Hydrogen recombines inside the battery. These use gas phase transfer of oxygen to the negative plates to recombine them back into water while charging and prevent the loss of water through electrolysis. The recombining is typically 99+% efficient, so almost no water is lost. Charging voltages for most AGM batteries are the same as for a standard type battery so there is no need for special charging adjustments or problems with incompatible chargers or charger controls. Since the internal resistance is extremely low, there is almost no heating of the battery even under heavy charger and discharger currents. AGM batteries have a very low self-discharger rate (from 1% to 3% per month). So they can sit in storage for much longer periods without charging. The plates in AGM's are tightly packed and rigidly mounted, and will withstand shock and vibration better than any standard battery.
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.
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).
