The battery, after being filled with acid needs to be initially charged to avoid the risk of sulfation. There are two common types of batteries convention lead acid batteries and sealed batteries also known as absorbed glass matt(AGM) batteries.
The battery is stored without sulfuric acid (electrolyte) and to activate it acid is added. Without acid it has an indefinite shelf life.
Conventional Battery Activation
A conventional battery is normally filled with acid at the place you buy it from. They should allow 30 minutes to let all the air bubbles escape from the battery while filling it and fill it exactly to the upper line. Yuasa actually recommends that the initial charging be done on the battery without the caps on. They recommend you charge it at an amperage equal to 1/10 of the batteries rated capacity, but in practice most people will only have a 2amp option available to them. They then recommend that you top off the acid level and this is the last time you will ever add electrolyte to the battery. Any additional top off should be pure water.
Sealed Battery Activation
First of all only use the acid pack that comes with the battery do not add any additional acid or water. After the acid pack is completely drained you should let the battery sit for 20-60 minutes (high performance batteries 1-2 hours). This allows the electrolyte to permeate into the plates for optimum performance. After the electrolyte is added your battery will have about 75-80% of its potential charge. On new motorcycles many manufacturers require the battery to be fully charged with the cap off with a deep solid state trickle charger to be eligible for warranty replacement. If you don't have a fancy automatic charger you should refer to any instructions included with the battery and aim to have a voltage of 12.8v after the battery is fully charged.
