The BLS uses patented Wave² Technology to handle the problem of sulfate build-up in lead acid batteries. It sends a signal that matches the frequency of the sulfate crystals, causing them to dissolve into lead and sulfuric acid. This restores the battery to a like new condition and/or extends the life of the battery.

Using the BLS

Connect the BLS directly to the batteries, in parallel with the charging source, the red wire to the main positive battery terminal and the black/red wire to the main negative battery terminal. Then use the battery system as normal.
