Beisite T0TRM 61Wh replacement battery

The Beisite T0TRM is a new 61Wh lithium-ion cell rated at 11.1V. It replaces Dell part numbers including T0TRM, 245RR, 0H76MY, H76MV, 07D1WJ, 7D1WJ, Y758W and 31CP6/44/77-2. Designed for XPS 15 9530 and Precision M3800 series laptops. The pack ships as a single black battery with a 12-month warranty.

Straightforward swap with basic precautions

Installation typically involves removing the bottom case screws, disconnecting the old pack and connecting the new one. Ensure the laptop is fully powered off and unplugged before starting. A common issue is forgetting to detach the internal battery cable first, which can cause a short. Handle the connector gently; forcing it may damage the motherboard header.

Ideal for XPS 15 9530 and Precision M3800 owners

This unit suits users restoring runtime on those specific Dell models. It is not for buyers needing a different voltage, capacity or form factor. Builders working on other Dell series or non-Dell machines should look elsewhere. Anyone requiring a higher-wattage pack or a different connector layout will need an alternative solution.

Questions about this item

How can I verify the 11.1V 61Wh battery is working correctly after installing it in my XPS 15 9530?

After installation, power on the laptop and check the operating system's battery report or BIOS to confirm the reported voltage reads near 11.1V and the design capacity shows 61Wh.

What is included in the package and do I need to purchase any tools or cables separately for my Precision M3800?

The package includes 1x battery only. No tools, cables, or additional hardware are included; reuse the existing screws and connectors from your Precision M3800 during replacement.

Which part number should I match — 31CP6/44/77-2 or 7D1WJ — to ensure compatibility with my XPS 15 9530?

Both part numbers are listed as direct replacements for the XPS 15 9530 series; match either 31CP6/44/77-2 or 7D1WJ against the label on your original battery to confirm fit.
