It depends on the exact Precision model, since this line spans about 327 compatible laptops and 29 distinct battery part numbers. Voltage runs from 11.1 to 15.2 V and capacity from roughly 51 to 97 Wh in 4-cell and 6-cell lithium-ion packs. Common part numbers include P45E001, 05041C, DVG8M1C, M59JH23, 451-BBG0, and 0M033W. To pin down the right one, match your model number (for example a Precision 5550 or 7750) or check the Service Tag.

Start with your exact model number or Service Tag, then match it against the part number printed on your current battery. The Precision line uses 29 different part numbers, such as P45E001 or 451-BBG0, across 327 models, so a close model name is not enough. Confirm the voltage (11.1 to 15.2 V) and capacity (51 to 97 Wh) listed on the pack match the replacement. Matching the printed part number is the surest way to get a compatible battery.

Precision replacement batteries in our catalog range from $42.99 to $89.99. Where your model lands depends on capacity and cell count, since packs run from about 51 Wh up to 97 Wh in 4-cell and 6-cell lithium-ion configurations. Higher-capacity 7000 series flagship batteries tend to sit at the upper end of that range, while smaller packs for entry-level units fall lower. Match your exact part number, such as M59JH23 or 0M033W, to see the price for your specific model.

No, not across the board. The Precision line uses 29 distinct part numbers with voltages from 11.1 to 15.2 V and capacities from 51 to 97 Wh, so a pack from one sub-series often will not fit or power another. For example, a 5000 series thin-and-light battery and a 7000 series flagship battery are different sizes and ratings. Always match the printed part number, such as DVG8M1C or 451-BBG0, rather than assuming two Precision models share a battery.

The main differences are physical size, capacity, and cell count. 3000 series entry-level units use lithium-ion packs that vary by model, 5000 series thin-and-light machines favor thinner high-capacity packs, and 7000 series flagships fit larger-capacity batteries up to about 97 Wh. Across all three, voltage ranges from 11.1 to 15.2 V in 4-cell and 6-cell formats. Because the chassis and component layouts differ, part numbers like P45E001 and 05041C are not shared between series.

Look at the label on the battery itself, which lists the part number alongside the voltage and watt-hour rating. On most Precision models you reach it by removing the bottom panel of the laptop. The part number is usually a short alphanumeric code such as 05041C, DVG8M1C, or 0M033W. You can also cross-reference your model number or Service Tag to confirm which of the 29 Precision part numbers applies before you order.

Yes, on most Precision models the battery is an internal pack reached by removing the bottom panel with a screwdriver. Power down, disconnect the charger, remove the base screws, unplug the battery connector, and swap in the matching pack, such as a 4-cell or 6-cell rated between 11.1 and 15.2 V. Match the printed part number, for example M59JH23, before you start. Take your time with the connector and screws so nothing is forced.

Watch for sharply reduced runtime, with a charge that drains far faster than when the laptop was new. Precision batteries are often used in heavy workstation roles, so noticeable degradation after 2 to 3 years is common. Other signs include the system shutting down before reaching zero percent, the battery refusing to hold a full charge, or the operating system flagging poor battery health. If runtime on your 51 to 97 Wh pack has dropped well below normal, it is time to replace it.
