The Gateway T Thinkpad uses a 6-cell lithium-ion pack, typically rated at 10.8V or 11.1V with capacity in the 4400mAh to 5200mAh range. Part numbers in this family include the SQU-715 and SQU-719 series, with some units carrying factory numbers like 934T2920F. Because configurations changed across the line, confirm the number printed on your existing battery before ordering. The replacement price in this category is $57.99.

Start with the specific model number on the label on the underside of your laptop, such as a T-1625 or T-6836. Then match it to the part number printed on your current battery, for example an SQU-715 or 934T2920F. Voltage runs 10.8V or 11.1V and cell count is usually 6-cell, but the exact part varies by sub-series and year. Matching both the model and the battery number is the reliable way to get a pack that fits and connects correctly.

A Gateway T replacement battery in this category is priced at $57.99. These are 6-cell lithium-ion packs in the common 10.8V or 11.1V range, with capacity around 4400mAh to 5200mAh. Since part numbers differ across sub-series like the T100, T580, and T61, confirm your exact model and the number on your old battery so the one you buy matches your machine.

Not always. Some models share a part-number family, such as the SQU-715 and SQU-719 series used across several T-1600 and T-6000 units, and voltages of 10.8V and 11.1V are often cross-compatible. However, the line spans multiple sub-series and years, so the connector, dimensions, and exact part can differ between models. The safe approach is to match the number on your current 6-cell pack rather than assume a battery from a similar-looking Gateway T fits.

The main differences are part number, capacity, and physical fit across sub-series like the T30, T100, and T580. Most use 6-cell lithium-ion cells at 10.8V or 11.1V, but capacity ranges from about 4400mAh to 5200mAh, with the higher figure giving longer runtime. Part-number families such as SQU-715 cover some models while factory numbers like 934T2960F appear on others. Always confirm the number on your existing pack before choosing a replacement.

Look on the battery itself. Remove the pack and read the label on its face, where you will see a number like SQU-719 or 934T2920F along with the voltage, usually 10.8V or 11.1V. You can also check the sticker on the underside of the laptop for the model number, such as T-6815. Having both the model and the battery part number makes it simple to confirm you are ordering the correct 6-cell pack.

Yes. Gateway T batteries on most models are removable packs that slide out of a bottom or rear bay after you release the latch. Power down, unplug the adapter, release the lock, and lift the old 6-cell pack free, then seat the new one until it clicks. No tools are usually needed. Confirm the replacement matches your part number, such as an SQU-715 family pack, and check the voltage of 10.8V or 11.1V before installing.

Common signs include much shorter runtime than before, the laptop shutting down even though it shows remaining charge, and the system running only when the adapter is plugged in. You may also notice the battery no longer reaching a full charge or draining quickly at idle. On a 6-cell Gateway T pack rated near 5200mAh, a steep drop in usable hours points to worn cells. When that happens, a fresh replacement at $57.99 restores normal unplugged use.
