Compatible HP Series

This replacement battery fits HP 248, 248 G1, 340, 340 G1, 350 and 350 G1 notebooks. It matches part numbers including 776622-001, 728460-001 and 752237-001. The 4-cell lithium-ion pack delivers 2200mAh at 14.8V for 32Wh of capacity. UL, CE, FCC and RoHS certifications cover the safety circuitry.

Upgrade From Worn Packs

Owners replacing a depleted original battery will regain full mobile runtime. The jump is worth it when the existing pack no longer holds a charge through a typical work session. Grade A cells and a smart control board protect against overloading and overheating during daily cycles.

For HP 248/340/350 Owners

This unit suits users of the listed HP series who need a direct-fit replacement. Buyers with other HP models or non-HP laptops should look elsewhere, as the connector and form factor are specific to the TPN-Q129 through TPN-Q132 platforms.

Questions about this item

Does the 4-cell 2200mAh 14.8V pack match the original HP 776622-001 dimensions and latch positions for the 248 G1 chassis?

Yes — the replacement is built to the same 4-cell form factor and connector layout as HP part numbers 776622-001, 728460-001 and 752237-001, so it seats in the 248, 340 and 350 series battery bay without modification.

Which step do installers most often skip when fitting this Li-ion battery into an HP 340 G1?

After sliding the pack home until the latches click, many forget to enter the BIOS and run the battery calibration cycle; without it the fuel gauge can misreport the 32 Wh capacity.

What component inside this FOCUSTEC pack will degrade first and require a full battery swap?

The four grade-A lithium-ion cells and the integrated protection circuit board age together; once the cells no longer hold a useful charge the entire 14.8 V pack must be replaced.
