Replacement Battery for Rugged Laptops

It carries the SP306-2 part number and is built to replace the original battery in compatible mobile workstations. The unit ships new and includes short-circuit, overheat and overload protection circuits.

Suited for Field Service and Industrial Users

Technicians who run LPG M3 through M6 series devices or Siemens Simatic Field PG M6 6ES7798-0AA10-0XA0 units will find a direct-fit replacement here. Buyers who need a different voltage, a higher capacity or a battery for another laptop family should look at other listings.

Capacity and Voltage Determine Compatibility

The decisive specification is the 89.42Wh capacity paired with a 10.8V nominal voltage. Matching both figures to the original battery label ensures the pack will fit physically and communicate correctly with the laptop's charging controller.

Questions about this item

How do I install the SP306-2 battery and what is the common mistake with the connector?

Open the back cover, verify the original battery model matches SP306-2, then connect the battery connector firmly to the motherboard; the step people get wrong is leaving the connector loose.

What maintenance will the SP306-2 battery need later?

Discharge the new battery to 5 percent, not zero, then charge and cycle three to four times to wake it up; repeat a full cycle every few months to maintain the 8280mAh capacity.

What limit appears first on the SP306-2 under sustained use?

The 10.8V 89.42Wh pack has short-circuit, overheat and overload protections that will cut power before the cells reach a thermal limit.
