原创 vent tube expensive bike

The original factory supplied 53030, Y60-N24AL-B, or 61 21 1 459 650  utilizes a flooded cell type construction and incorporates a .  In Siemens PLC sports bike applications the battery does not spend a lot of time in a .  Because the conventional flooded cell battery has a vent tube, the battery being at anything other than vertical may result in acid leaking from from the battery through the vent tube, and usually onto parts.

First, the Xtreme Volts XIX30L is rated at 30 amp hours.  This is a 2 amp hour increase over the stock BMW supplied battery, giving you almost 10% more starting power.  The Xtreme Volts XIX30L also carries a higher Cold Cranking Amp (CCA) factory rating.  The  also eliminating the venting of hazardous  CR123A lithium battery  hydrogen gas under normal operating and charging conditions.  In addition, the absence of a vent tube means no acid leaking from the battery. 
 The Xtreme Volts version of the XIX30L is constructed as a true factory sealed Gel Cell, maintenance free (MF), valve regulated lead acid battery (VRLA).   What does this means to the battery user? First, factory sealed means the battery comes with the acid already installed. The battery is permanently sealed, so there is no acid to handle.  Next, Gel Cell construction incorporates a geling agent in the acid.  This give the acid a jello like consistency when fully charged.  This eliminates free floating acid in the battery, and  the chance of acid leaking from the battery even when the battery case is damaged.  The gel also acts a dampener, or cushion against shock and vibration, making this battery well suited for motorcycle applications, as well as rugged, pounding conditions as may be encountered with Yamaha snowmobile, PWC, and ATV applications.  Third, ghd hair straightener   it is maintenance free (MF).  There is no need to check or maintain fluid levels in the battery.  Finally, a valve regulated lead acid (VRLA) battery does not have a vent tube.  Vapors produced by the battery are re-circulated back into the battery.
