This 7.7 V lithium-polymer pack delivers 38 Wh and 4960 mAh for the HP EliteBook Folio G1 and V1C37EA models. It matches part numbers EO04XL, 827927-1B1, 827927-1C1, 828226-005, HSTNN-I73C and HSTNN-IB7I. The unit is supplied new and ready to install.

Upgrade From a Depleted Original

Questions about this item

Will the EO04XL battery fit my HP EliteBook Folio G1 without modification?

The EO04XL is listed as compatible with the HP EliteBook Folio G1 and V1C37EA models. The supplier notes that even with the same laptop model the internal battery can differ, so verify the original battery matches the product photo before fitting.

What is the correct way to install the EO04XL and what step do people often miss?

After placing the battery, reconnect the cable securely and ensure the connector orientation matches the original. A common mistake is not checking that the connecting wire length and battery size suit the chassis, which can prevent proper installation.

How should I maintain the EO04XL to prolong its lifespan?

Use the original charger, avoid discharging below 5 percent and stop charging at 95 percent. Do not let the battery reach 0 percent and do not keep it fully charged for long periods.
