HP C Chromebook models use a lithium-ion battery in the 7.7 to 11.4 V range, with L42550-1C1 being a common part number for several builds. Capacity falls within the line’s 35 to 103 Wh span depending on the configuration. Because Chromebook packs are usually internal, you reach them by removing the bottom cover. Confirm the part number printed on your current battery before ordering, since closely related Chromebook units do not always share the same pack.

Match your full laptop model number with the part number printed on your current battery. Start by checking the label on the pack or under the bottom cover for a code such as HSTNN-IB72 or L42550-1C1. Then confirm the voltage matches one in the 7.7 to 11.4 V range. With 24 distinct part numbers across roughly 1847 compatible models, the exact model and part number are what guarantee a correct fit rather than the sub-series name alone.

HP C replacement batteries range from $55.99 to $87.99. Where your pack lands in that range depends on the sub-series, the cell count, and the capacity, which spans about 35 to 103 Wh. A smaller, lower-capacity Chromebook pack typically sits toward the lower end, while a higher-capacity multi-cell battery for a C14 or C300 trends higher. Matching your exact part number, such as HSTNN-IB8W, helps you confirm the right price for your model.

Not reliably. While some closely related models within the older Compaq Presario C-series shared packs, the broader HP C line uses 24 different part numbers across voltages from 7.7 to 11.4 V and capacities from 35 to 103 Wh. A Chromebook pack like L42550-1C1 will not fit a model that takes an HSTNN-series battery such as HSTNN-DB72. Always confirm both the model number and the part number on your current battery before treating any two packs as interchangeable.

The sub-series differ in cell count, capacity, voltage, and part number. Capacity across the line runs from about 35 to 103 Wh, and voltage from 7.7 to 11.4 V, so a compact Chromebook pack is built differently than a higher-capacity C14 or C300 battery. Part numbers also vary by sub-series and year, ranging from L42550-1C1 to HSTNN-IB72 and HSTNN-IB8W. The install approach is similar across most sub-series since these packs are generally internal.

On the battery label itself, which usually lists a code such as HSTNN-DB72, HSTNN-Q36C, or HP484170-001. For internal packs, you reach the label by removing the bottom cover. You can also check the service sticker on the underside of the laptop for the full model number, then cross-reference it. Having both the model number and the printed part number ensures you pick the correct one from the 24 part numbers covering this line.

Yes, in most cases. Many HP C sub-series use internal lithium-ion packs, so you remove the bottom cover, unplug the connector, and seat the new battery, often with a small Phillips screwdriver. Older removable-style packs release with a latch and no tools. Either way, match the part number first, for example HSTNN-IB72 or L42550-1C1, and confirm the voltage falls in the 7.7 to 11.4 V range before installing.

Watch for runtime that drops sharply from a full charge, the laptop shutting down well before it reaches zero percent, or the system staying on only while plugged in. A battery health reading far below its rated capacity (these packs are rated from about 35 to 103 Wh) is another clear sign. If your charge no longer holds, a replacement in the $55.99 to $87.99 range that matches your part number, such as HSTNN-IB8W, will restore normal runtime.
