Battery YTX4L-BS Yuasa Combipack with electrolyte

The manufacturer Yuasa is one of the best known in the world of batteries; quality is assured.
The battery comes unactivated. Supplied with acid

The Yuasa batteries are manufactured to exceed the expectations of drivers and vehicle manufacturers, being the number 1 manufacturer of motorcycle batteries. The positive electrode of Yuasa brand batteries is made of lead dioxide, while the negative is made of porous lead.
The other way to send them is dry, that is, empty. They are shipped together with the electrolytes stored in plastic containers to fill them when they are ready for activation. Once the seal is removed, it must be installed immediately or it may oxidize.

The Yuasa brand batteries are recommended for their high quality and durability.

For starting up and charging the battery with acid:
You just have to remove the plugs from the battery tubes (top part), fill it with acid, wait two hours (without putting the plugs back), then clean any acid that has come out with paper or a cloth and put the plugs back on.
And depending on the battery, it is already ready to use.
You need to connect the red to positive and black to negative and start the motorcycle; the same ride will charge the battery. Some people prefer to charge it before use to ensure the battery is at 100% of its charge.
