Replacement battery for HP Pavilion 14-AL and 14-AV

This TOPKTEAM SE03XL lithium-ion battery replaces part numbers including 849568-421, HSTNN-LB7G and SE03041XL. It fits HP Pavilion 14-AL and 14-AV series notebooks such as the 14-AL001NG, 14-AL102NG and 14-AV002LA. The cell chemistry is Li-ion and the colour is black.

Steady discharge at 11.55 volts and 3450mAh capacity

Rated at 11.55 volts and 3450mAh, the pack delivers 41.5Wh of energy for sustained operation. Under continuous load the voltage remains stable at the nominal level until the stored charge is depleted. No internal fan or active cooling is present, so heat dissipation relies on the laptop chassis.

Compatibility is restricted to the specific HP Pavilion 14-AL and 14-AV models and the part numbers shown in the compatibility list. It will not work with laptops outside that list or with systems requiring a different voltage, connector or form factor. Buyers who need a battery for another series or a higher capacity must choose a different product.
