User Manual & Warranty Card
12V Repair can take up to four (4) hours to complete the recovery process and for use on 12-volt lead-acid batteries with a voltage higher than
2V only. Please note that not all batteries can be recovered. The effectiveness of the repair will depend greatly on the degree of damage to the
battery. In general, the more severe the damage to the battery, the more difficult, if not impossible, the repair will be.
When the connected battery's voltage is between 0.3V and 2V, and the 12V, 12V AGM or 12V Lithium mode is selected, this icon will flash
automatically. Press the Confirm button to enter a 5-minute force charge. (It can only be activated by pressing Confirm button)
