These premium Power House maintenance-free AGM and VRLA batteries for 12V models from Hazelwood, Missouri based Mid-USA Motorcycle Parts have been designed to eliminate the need to ever add water to the battery.
The sealed enclosure allows mounting the battery in any position (except upside-down) and to help improve vibration resistance, the battery acid is absorbed between the plates with fine microfiber glass mats (AGM) and the internal gas pressure is valve-regulated (VRLA) to prevent any water loss.
|AGM and VRLA maintenance-free 12 volt batteries for increased cold cranking amps and dramatical sulfation reduction.|
The AGM and VRLA construction, combined with lead calcium grid plates, is said to "provide more cold cranking amps than lead acid type batteries, with up to three times the life span."
They include a sulfation retardant that dramatically reduces the battery-killing plate sulfation that is commonly associated with conventional batteries.
They have an extremely slow rate of self-discharge when not in use, and must be slow charged at least every three months if not in service. Cable mounting hardware is included. They are available for a wide range of Touring, Softail, Dyna, V-Rod and Sportster applications from 1973 and up.
Also made in the USA by Yuasa, these lead acid batteries are the same batteries that are made for Harley-Davidson. The Power House standard line features patented separators that allow two extra plates per cell for +30% more power and between 5% and 8% more cold cranking power than the standard hi-torque low maintenance output series. There is less maintenance required because of advanced lead calcium technology instead of conventional lead antimony.
This means a massive -90% reduction in water loss due to gassing. By incorporating the latest in battery technology, each Power House hi-torque battery "delivers the ultimate in value". All batteries are shipped dry, without acid, and include instructions on how to fill the battery. Terminal hardware and a vent tube also included.
If you are increasing the power available to start a bike, then Mid-USA says that dealers could do worse than installing a Power House ignition module - available as stand-alone units or complete install kits for selected single cam Big Twins from 1970 to 1999 (except EFi) and Sportsters 1971-2003 (plus 1996-2003 1200S), except those equipped with a lean angle switch.
Fully adjustable and for use with kick or electric start, they can be used as dual or single fire with choice of single or multi-spark mode and have 10 different advance curves.
