Pulsetech QuadLink 100x004
The QuadLink works with any 6-volt or 12-volt battery maintenance charger up to 8 amps using the standard 2-prong output connector. The capabilities of your current charger are simply being passed through to the batteries via the QuadLink so the battery charger is always in full control of the charging process. In other words, the QuadLink is almost transparent to the battery. The QuadLink does NOT change the charging capabilities of the battery charger it is connected to, but simply increases the number of batteries that can be charged.
