Yes, in the overwhelming majority of Acer Chromebook models, the battery is a replaceable module. It is held by screws and connected by a plug-in cable or ribbon, with no soldering and no structural adhesive in most clamshell designs. The practical answer, however, depends on the model. Acer has shipped Chromebooks across a wide range of chassis generations, from budget education models to premium convertibles, and the access path to the battery varies from a straightforward ten-screw bottom cover removal to a more involved disassembly that some manufacturers recommend leaving to authorised service centres.<\/p>\n
This guide covers which Acer Chromebook models have replaceable batteries, the battery part numbers associated with the major model families, the replacement procedure and its difficulty, global cost data for DIY and professional replacement, and the calibration steps required after installation.<\/p>\n
Acer Chromebook batteries fall into three categories based on how they are secured and how deeply they are buried in the chassis.<\/p>\n

The second category is less common and applies mainly to convertible and ultra-thin designs. The third category is a support classification rather than a physical constraint: a battery can be physically replaceable while still being designated as a field-replaceable part rather than a customer-facing procedure. The practical reality is that most Acer Chromebook batteries are reachable with a Phillips screwdriver and a plastic pry tool.<\/p>\n \n 2. Battery Part Numbers by Model Family<\/h2>\nThe single most important step before ordering a replacement is identifying the exact battery part number for your specific Chromebook. Acer has used a wide range of battery models across its Chromebook line, and they are not interchangeable across chassis generations.<\/p>\n 2.1 Chromebook 714 and 715 (CB714, CB715, Spin 7 SP714)<\/h3>\nThe Chromebook 714 and 715 families use the AP18F4M<\/strong> battery, also designated KT.00404.001<\/strong> and 2ICP5\/54\/90-2<\/strong>. The specification is 7.6V, 56Wh, 7380mAh, 4-cell Li-ion<\/strong>. Fitment covers the CB714-1W, CB714-1WT, CB715-1W, CB715-1WT, and Spin 7 SP714-61NA series.<\/p>\n Replacement pricing for the AP18F4M spans a wide range depending on source and certification. A genuine Acer replacement battery is listed at approximately $55.41<\/strong> (approximately US$42.50 before tax) from one retail source. A third-party replacement from a marketplace seller is listed at $125.99<\/strong> for the 56Wh variant. The price gap illustrates the importance of checking whether a listing is for a genuine OEM pack or a third-party equivalent.<\/p>\n This family uses the AC14B8K<\/strong> battery, with cross-compatible part numbers including AC14B3K<\/strong>, AP14B8K<\/strong>, KT.0030G.004<\/strong>, KT.0040G.004<\/strong>, and MS2392<\/strong>. The specification is 15.2V, 48Wh, 3220mAh, Li-ion<\/strong>.<\/p>\n Fitment covers the Chromebook 13 and 15 series, C810, C910, CB3-531, and CB5-571, and the same battery is used across a wide range of Acer Aspire, Swift, and Nitro laptops. A replacement is listed at approximately $104.98<\/strong> from one North American retailer.<\/p>\n The C720 and C740 families use the AP13J7K<\/strong> long-cable battery, with cross-compatible part numbers including AP13J3K<\/strong>, AP13J4K<\/strong>, KT.00304.001<\/strong>, KT.00304.004<\/strong>, and KT.00304.008<\/strong>. The specification is 11.4V, 44.6Wh, 3920mAh, 3-cell Li-ion<\/strong>.<\/p>\n Replacement pricing for this family is listed at approximately $155.00<\/strong> from one marketplace seller, though availability and pricing fluctuate significantly for older Chromebook generations. The same battery family is also used in some Spin 512 configurations under the AP13J3K and AP13J4K part numbers.<\/p>\n This broad family uses the AP18C8K<\/strong> and AP18C4K<\/strong> batteries, with a specification of approximately 11.25V\u201311.55V, 50Wh<\/strong>. Fitment covers the Chromebook 311 (C722), 314 (C933LT, C933L, C933), 315 (CB315-3HT, CB315-3H), C871 (C933T), R753T, and Spin 512 (R856TN).<\/p>\n A separate Spin 512 battery family uses the AP13J3K<\/strong> or AP13J4K<\/strong> at 11.25V, 3950mAh, 44.44Wh<\/strong>, with cross-compatible part numbers including KT.00307.006<\/strong>, KT00304001<\/strong>, and 3ICP5\/67\/90<\/strong>. A replacement for this variant is listed at approximately $50.44<\/strong>.<\/p>\n An additional Spin 512 battery option is the AP23A7L<\/strong> at 11.25V, 53Wh, 4750mAh, Li-polymer<\/strong>.<\/p>\n The newer CB315-4H and CB314-4H chassis use a battery that is reached after removing ten Phillips screws<\/strong> from the base cover. A replacement guide for the CB315-4H-P8FZ specifies battery discharge below 25%, removal of ten 6mm Phillips screws, and careful release of the battery connector after lifting transparent and black tape. The CB314-4H service documentation follows a similar procedure: ten base-cover screws, base cover removal, then detachment of transparent mylar and battery cable tape before the pack can be lifted from its guide pins.<\/p>\n The C810 and C910 use the AC14B8K family. A replacement guide for the C810-T7ZT specifies removal of thirteen 6.0mm Phillips #1 screws<\/strong> from the bottom cover, followed by prying the cover along the edge to release the clips. The battery connector is released by alternating pressure on both sides with a spudger, and the battery itself is secured by two 3.0mm Phillips #0 screws<\/strong>.<\/p>\n The CB3-431 uses a battery secured by two 4.5mm Phillips screws<\/strong> after the bottom cover is removed. The bottom cover is held by ten screws<\/strong>: eight 6.6mm screws and two 4.2mm screws. The battery connector is released by lifting the small tabs on either side of the connector with a fingernail or spudger.<\/p>\n Despite differences in screw counts and battery part numbers, the structural logic of Acer Chromebook battery replacement is consistent across the models covered here. The sequence below describes the common path, with model-specific deviations noted where relevant.<\/p>\n Discharge the battery to below 25%<\/strong> before disassembly. A pack near full charge stores more energy, and accidental damage during removal carries a higher risk of thermal event. Power off the Chromebook completely\u2014not sleep\u2014and disconnect the charger and all peripherals.<\/p>\n If the battery is visibly swollen\u2014indicated by a lifted trackpad, a bulging bottom panel, or a chassis that no longer sits flat\u2014stop using the device and disconnect AC power immediately. Swollen lithium batteries are a fire risk and should be handled carefully or by a professional. Do not puncture, bend, or compress a swollen pack.<\/p>\n Place the Chromebook face down on a soft, non-abrasive surface. Remove all Phillips screws from the bottom cover. The count varies by model: ten 6mm screws<\/strong> on the CB315-4H, thirteen 6.0mm screws<\/strong> on the C810, ten screws<\/strong> on the CB3-431 (eight 6.6mm and two 4.2mm), and ten screws<\/strong> on the CB314-4H.<\/p>\n Insert a plastic pry tool or opening pick into the seam between the bottom cover and the chassis. Work around the perimeter, levering every two centimetres or so, until the cover releases. If resistance is encountered, re-check for a missed screw rather than prying harder.<\/p>\n The battery connector is the first internal connection to sever. On most models, it is a press-fit connector on the system board, often covered by transparent mylar tape or acetate tape that must be lifted first. Release the connector by sliding a plastic spudger under the connector edge and lifting gently, or by alternating pressure on both sides of the connector with a fingernail. On the C810, the connector may require significant alternating pressure before it releases; do not pull on the cables.<\/p>\n Most Acer Chromebook batteries are secured by two to six Phillips screws<\/strong>. The C810 uses two 3.0mm screws. The CB3-431 uses two 4.5mm screws. The CB315 and CB314 families use screws that are revealed after the tape is lifted. Remove the screws in a diagonal pattern to distribute pressure evenly.<\/p>\n Once the connector is free and the mounting screws are removed, lift the battery out of its bay. Some models use guide pins that the battery sits on; lift to release the pack from the guide pins. Avoid touching the exposed gold contacts on the battery connector.<\/p>\n Chromebook batteries are inexpensive relative to most laptop batteries. The general range for Acer Chromebook replacement parts is $25\u2013$60<\/strong> for compatible third-party packs, with genuine Acer batteries typically ranging from $60 to $150<\/strong>. Representative pricing for specific part numbers:<\/p>\n Third-party alternatives from reputable brands typically cost between $35 and $80<\/strong>. For a budget Chromebook, the difference between a $50 pack and a $100 pack is meaningful, but the cheapest listings may use lower-quality cells that deliver reduced capacity within months.<\/p>\n Professional service adds labour on top of the part cost. The general range for Chromebook battery replacement labour is $30\u2013$60<\/strong> at independent repair shops, with some models using adhesive that requires careful heating and adds to the labour time. A national repair chain quotes approximately $99<\/strong> including labour and a one-year warranty for a Chromebook battery replacement.<\/p>\n Regional pricing varies widely. Service centres in New Zealand quote battery replacements from $150<\/strong> (NZD), with OEM-grade cells at $120\u2013$180<\/strong>. Service centres in Slovakia quote Acer Chromebook battery replacement from \u20ac50<\/strong>. Service centres in Vienna quote cell replacement from \u20ac149<\/strong> with a six-month warranty, following a \u20ac25<\/strong> diagnostic check. Service centres in Singapore quote HP laptop battery replacement at S$108 to S$186<\/strong> depending on model, which is a comparable range for premium laptop service in that market.<\/p>\n These figures establish the professional-service range: roughly 2\u20133\u00d7 the DIY part cost<\/strong> in higher-labour-cost markets, and closer to 1.5\u00d7<\/strong> in lower-labour-cost markets.<\/p>\n After installing a replacement battery, charge to 100% and discharge to the low-battery warning before returning to normal use. This allows the battery management system to learn the new pack’s full and empty points. Without this cycle, the reported percentage may be inaccurate for the first few days. A more thorough calibration involves draining the battery until the Chromebook shuts down on its own, leaving it off and unplugged for a few hours to reset the gauge’s zero point, then charging uninterrupted to 100%.<\/p>\n Chromebooks expose battery diagnostics through the ChromeOS Diagnostics app, which reports design capacity and current full-charge capacity. After calibration, the full-charge capacity should be close to the design capacity for a new pack. A substantially lower reading suggests a low-quality cell, an incorrect part, or a calibration error.<\/p>\n For a more detailed report, open the Chrome Shell (CROSH) by pressing Ctrl<\/kbd>+Alt<\/kbd>+T<\/kbd> and run the battery diagnostic command. The CROSH interface also provides access to the Powerwash function for a factory reset, though Powerwash is not required for battery replacement and does not affect battery calibration.<\/p>\n Chromebooks do not expose the same charge-threshold controls as Windows laptops through Dell Power Manager or HP Battery Health Manager. The operating system manages charging automatically, and there is no user-facing 80% limit in the standard ChromeOS settings. For a Chromebook that spends most of its life on a desk, the practical intervention is to avoid leaving it plugged in at 100% continuously where possible, though the OS does not provide granular control over this behavior.<\/p>\n Two scenarios warrant professional service rather than a DIY attempt. The first is a battery that is severely swollen and firmly wedged against the chassis. The extraction force required in this situation risks puncturing the cell or cracking the trackpad, and a repair shop with the correct pry tools and replacement chassis parts is the safer path. The second is any uncertainty about whether the fault is the battery or the charging circuit. Replacing a battery will not fix a failed charging port or motherboard circuitry, and a diagnostic step before purchasing a part is worth the cost.<\/p>\n Some Chromebook 15 CB315-1H configurations carry documentation stating that battery replacement must be performed by an Acer-authorised repair facility. This is a support classification rather than a physical constraint, but it is worth checking the documentation for your specific model if the device is still under warranty. A DIY repair may void warranty coverage even if the procedure is physically straightforward.<\/p>\n For a non-swollen, out-of-warranty Acer Chromebook with confirmed capacity loss, the replacement is a 10-to-20-minute task with a Phillips screwdriver set and a plastic pry tool. The chassis is not glued shut on the generations covered here, the battery connector is accessible, and the fastener layout\u2014while varied across models\u2014is documented in iFixit guides and Acer lifecycle extension manuals.<\/p>\n The Acer Chromebook battery is a replaceable module in the overwhelming majority of models. It is held by two to six screws, connected by a plug-in connector, and free of solder and structural adhesive in the clamshell designs that make up most of the line. Replacement parts range from $25 to $60<\/strong> for compatible packs, and the procedure is rated “Easy” with a 10\u201320 minute completion time for most models.<\/p>\n The caveat is model identification. Acer has used at least six distinct battery families across its Chromebook line\u2014AP18F4M, AC14B8K, AP13J7K, AP13J3K, AP18C8K, and AP23A7L\u2014and they are not interchangeable. The battery label inside the chassis and the full model number are the only reliable identification methods. For a Chromebook line that shipped the same product name with different energy envelopes across generations, that extra step is not optional.<\/p>\n For a desk-bound Chromebook, the combination of a replaceable pack and a periodic calibration cycle is what determines whether the laptop still delivers usable runtime in year four. The battery will degrade; the question is whether you replace it on your own schedule or the degradation schedule chooses for you.<\/p>\n Battery part numbers and capacities vary by exact model, region, and configuration. Always verify the correct part using the label on the existing battery and the Chromebook’s full model number before purchase. Lithium-ion batteries require disposal through a certified recycling facility.
