RECOMMENDED CHARGERS FOR POWERSPORTS APPLICATIONS
(PC535, PC545, PC625, PC680, PC925)
There are two types of chargers for powersports applications, depending on the way the battery is used. The first type is the cyclic use charger, required in situations where the battery will be deeply discharged each time and must be recharged relatively quickly. All recommended chargers can be connected and operated indefinitely.
The second type is the storage use charger, required when the battery must be maintained at a high state of charge. Custom V-twin motorcycles are a typical application requiring this type of charger. These bikes are typically ridden for short distances and the battery has to provide multiple starts. Several days’ of this type of usage causes the battery to fail prematurely due to insufficient charge. A storage use charger must be connected to the battery whenever the bike is not in use. This will keep the battery at a high state of charge and eliminate premature failure due to repeated undercharge.
