12v 9Ah Sealed Motorcycle Batteries Overcharging Protection Long Service Life

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.

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.
