Battery Function The battery stores the electricity generated by the spool and magnet on the machine. It also acts as an electric drive/driver for components that need it, such as lamps, horns, electric starters, and others. It also serves as the voltage stabilizer of your Honda motor. More Safe The valve/safety filter helps remove excess gas caused by over-charging pressure. More Stable The grids are made of special materials that have low-resistivity values so that the storage of the current in the battery is maximized. Stronger & Leak-Proof The cover is a precise fit with the battery cover (sealed cover) so that the Honda Genuine Battery is stronger and does not leak.
