Genuine HP 51Wh 3-cell battery

This genuine HP TPN-DB1E battery supplies 11.55V and 51Wh from three lithium-ion cells. It fits HP Envy 13-AY, 13-BD, 15-ED, 15-EE, 15-ES and Pavilion 14-EH series laptops. Owners of those models can restore original runtime with a direct replacement part number L76965-2C2.

No bundled accessories included

The unit ships alone without cables, manuals or extra hardware. Buyers reuse their existing charger and mounting hardware. The bare-battery format keeps cost down for users who only need the cell pack itself.

51Wh capacity for compatible ultraportables

The 4195mAh pack delivers typical all-day office use on supported 13-inch and 15-inch Envy models. It will not fit laptops outside the listed Envy and Pavilion 14-EH families. Buyers needing higher capacity or different form factors must choose another part.

Questions about this item

How many charge cycles before the 51 Wh BN03XL 3-cell pack drops below 80 % capacity?

HP does not publish a cycle-count rating for the TPN-DB1E; treat it as a consumable and plan replacement when runtime no longer meets your needs.

What is the first limit reached during continuous discharge of the 11.55 V 4195 mAh battery?

The 51 Wh energy capacity is the hard limit; once depleted the pack must be recharged before the laptop can run again.

Does the 3-cell Li-ion unit generate noticeable heat or fan noise during all-day use?

The battery itself is passive and silent; any warmth or fan activity comes from the laptop's own thermal management, not from the pack.
