Purpose-built power

The Beisite 3581A7PH-1S4P is a 68.4Wh lithium-ion battery built to replace the original pack in Autel diagnostic scan tools. Technicians who rely on uninterrupted vehicle scans gain a direct-fit 3.8V 18000mAh unit that restores factory runtime without modification.

Sustained output

The cell chemistry maintains a stable 3.8V through long diagnostic sessions, avoiding the voltage sag that can interrupt data logging or ECU flashing. Consistent delivery means the tool stays active for the full 68.4Wh capacity rather than cutting out early under load.

Fit and finish

A black moulded housing matches the scanner’s original contours and latch points, so the battery seats securely with no gaps or wobble. The single-pack design replaces the OEM part number 3581A7PH-1S4P directly, letting technicians swap packs in seconds and return to work.

Questions about this item

Does the 3.8V lithium-ion cell generate noticeable heat or drain quickly when the Autel scanner runs all day?

The 68.4Wh pack is rated for full-day diagnostic sessions; lithium-ion chemistry keeps self-heating low under normal load.

What must I already own for this 3581A7PH-1S4P pack to power my tool?

You need an Autel diagnostic scanner that accepts the 3581A7PH-1S4P part number and a 3.8V charging circuit built into that device.

Will this 18000mAh replacement work alongside the original battery if I keep both?

Only one pack fits the scanner at a time; swap the old unit for this 68.4Wh replacement when the original no longer holds charge.
