Questions about this item

Which Greenworks 82V tool models accept the GL250, GL500, GL900, GL600, G82B25 or GL400 battery part numbers?

This battery replaces the GL250, GL500, GL900, GL600, G82B25 and GL400 packs used in the GC82BC brush cutter, GBB600 string trimmer, GM210 21-inch push mower and PC82ST pole saw.

Will the 82.0V 4500mAh pack run my older 82V Greenworks mower and string trimmer without modification?

Yes, the 82.0V output matches the original specification so it powers existing 82V Greenworks tools such as the GM210 mower and GBB600 trimmer directly.

How can I verify the battery is delivering its rated 328.0Wh after the first charge?

Run a compatible tool until the pack cuts off; a full discharge close to 328.0Wh confirms the 4500mAh capacity is performing to spec.
