high amp motorcycle battery,
agm sealed lead acid battery
Notice of motorcycle battery use:
1, Flames, sparks,burning cigarettes or other ignition sources must be kept away from battery when it is charging because the battery generates explosive gasses during vehicle operation.
2, When charging batteries, work in a well ventilated area - never in a closed room. Always turn the battery charger or ignition off before disconnecting a battery.
3, Keep out of the reach of children or the personnel who do not understand the manual. It may cause blindness or severe burn.
4, When using the battery ,handle with care,sulfuric acid may cause blindness or severe burn.
Sealed Lead Acid battery
The first sealed, or maintenance-free, lead acid emerged in the mid-1970s. Engineers argued that the term “sealed lead acid” was a misnomer because no lead acid battery can be totally sealed. To control venting during stressful charge and rapid discharge, valves have been added that release gases if pressure builds up. Rather than submerging the plates in a liquid, the electrolyte is impregnated into a moistened separator, a design that resembles nickel- and lithium-based systems. This enables operating the battery in any physical orientation without leakage.
The sealed battery contains less electrolyte than the flooded type, hence the term “acid-starved.” Perhaps the most significant advantage of sealed lead acid is the ability to combine oxygen and hydrogen to create water and prevent dry out during cycling. The recombination occurs at a moderate pressure of 0.14 bar (2psi). The valve serves as a safety vent if the gas buildup rises. Repeated venting should be avoided as this will lead to an eventual dry-out.

Answers to Common Questions about Batteries
1, Do lead acid batteries discharge when not in use?
All batteries, regardless of their chemistry, will self-discharge. The rate of self-discharge for lead acid batteries depends on the storage or operating temperature. At a temperature of 80 degrees F. a lead acid battery will self-discharge at a rate of approximately 4% a week. A battery with a 125-amp hour rating would self-discharge at a rate of approximately five amps per week. Keeping this in mind if a 125 AH battery is stored for four months (16 weeks) winter without being charged, it will loose 80 amps of its 125-amp capacity. It will also have severe sulfation, which causes additional loss of capacity. Keep your batteries charged while not in use!
2, Do lead acid batteries develop a memory?
Lead acid batteries do not develop any type of memory.
3, Do I need to completely discharge my lead acid battery before recharging it?
No, in fact you should never discharge your lead acid battery below 80% of its rated capacity. Discharging it below this point or 10.5 volts can damage it.
4, When do I need to perform an equalization charge?
Equalizing should be performed when a battery is first purchased (called a freshening charge) and on a regular basis (every 10 discharge cycles or at least once a month). Reduced performance can also be an indicator that an equalizing charge is needed.
5, What is an equalizing charge?
An equalizing charge for a 12 volt battery requires that it be charged with a voltage of at least 14.4 volts for a period of at least one hour once a month, or every 10 discharge cycles. An equalizing charge prevents battery stratification and reduces sulfation, the leading cause of battery failure.
