The Asus A A27 uses a lithium-ion battery that falls within this category’s 7.6 V to 14.4 V range and roughly 31 to 87 Wh capacity. Because the A line includes both removable and internal designs, the exact pack varies, so check the part number printed on your current battery against our listed options such as 0B200-01130100 or A31-K56. Prices for compatible A batteries run from $47.99 to $70.99. Matching your printed part number is the surest way to get the correct fit.

Find the exact model and part number printed on your current battery or on the label under the laptop, then match it to our listings. The Asus A category covers about 734 models across 15 distinct part numbers, including 0B200-01390000 and A31-K56, so the part number is what guarantees a fit. Voltage ranges from 7.6 V to 14.4 V and capacity from about 31 to 87 Wh, and similar-looking models can take different packs, so never guess based on the model name alone.

Asus A replacement batteries cost between $47.99 and $70.99, depending on the sub-series, cell count, and capacity. Lower-capacity internal packs around 31 Wh tend to sit toward the bottom of that range, while higher-capacity 6-cell removable batteries up to about 87 Wh sit higher. Across the category there are 15 distinct part numbers, such as 90R-N3VBA1000U and 70-NXM1B1200Z, so confirm yours to see its exact price before ordering.

No, Asus A batteries are not universally interchangeable, even between models with similar names. The line spans 7.6 V to 14.4 V and 31 to 87 Wh across both removable 6-cell and internal 2- to 4-cell designs, so a pack from one sub-series often will not fit another. For example, a classic A32-family removable battery will not work in a later internal-battery model. Always match the exact part number, such as A31-K56 or 0B200-01130100, to be sure.

The main differences are cell count, capacity, voltage, and whether the pack is removable or internal. Classic sub-series like A6000 and A32 commonly use removable 6-cell 11.1 V batteries, while compact A13 and modern configurations use slimmer internal packs that require opening the bottom casing. Capacities range from about 31 Wh to 87 Wh and voltages from 7.6 V to 14.4 V. That spread is why part numbers like 70-NXM1B1200Z and PP21AT149Q-1 are not interchangeable across sub-series.

Look at the label printed directly on your current battery, where you will see a code like 0B200-01390000 or A31-K56. On removable models, release the latch and slide the battery out to read the full label. On internal models, the number may also appear on a sticker on the underside of the laptop or inside the bottom casing. This part number is the most reliable way to match one of the 15 options in our Asus A category.

Yes, in most cases you can. On classic Asus A models like the A6000 and A32 sub-series, the 6-cell battery is removable with a latch and swaps out in seconds, no tools needed. On thin-and-light and modern models such as A13, the battery is internal, so you remove the bottom casing screws to access it. Either way, confirm your part number first, for example 90R-N3VBA1000U, so the replacement fits and seats correctly.

Common signs include much shorter runtime, the laptop shutting down unexpectedly, the charge percentage jumping or sticking, and the system running only when plugged in. If a battery that once held several hours now lasts well under an hour, it is likely worn. Asus A packs range from about 31 Wh to 87 Wh when new, so a steep drop from rated capacity points to replacement. Match your exact part number, such as PP21AT149Q-1, when ordering a fresh one.
