myVolts JC03 laptop battery 41.6Wh 3-cell 14.6V

Replacement battery for HP 15 17 246 255 series

The myVolts JC03 is a new lithium-ion battery rated at 14.6 volts and 41.6 watt-hours in a three-cell black pack. It replaces original HP part numbers including 919681-421 HSTNN-LB7V HSTNN-LB7W HSTNN-PB6Y and the JC04 reference. The unit fits HP 15-BS 15-BW 17-BS 15Q-BU 15G-BR 17-AK 15Q-BY Pavilion 17z and HP 246 G6 255 G6 250 G6 notebooks listed by the supplier. Buyers with other HP models or non-HP laptops should verify compatibility before purchase.

Lithium-ion chemistry and three-cell layout

The pack uses standard lithium-ion cells at a nominal 14.6 volts, a voltage fixed by the three-cell series arrangement. Capacity is set at 41.6 watt-hours, which determines the energy available per charge cycle. No higher-capacity or alternative-chemistry version is described in the data. Systems that require a different cell count or voltage will not accept this battery.

41.6 watt-hour capacity decides fit

The single figure that confirms whether this part suits a given machine is the 41.6 watt-hour rating paired with the 14.6 volt output. Match both numbers against the original battery label or the HP service part list for the exact notebook model. If the original shows a different watt-hour value or voltage, this pack is not the correct replacement.
