Kobalt is the latest power tool brand to introduce tabless batteries, launching the 24V Max Ultimate Output TXP line. This move follows a trend started by Milwaukee more than three years ago, with competitors like Ridgid, Metabo HPT, and Ryobi already offering similar technology. Kobalt’s entry into the tabless market highlights a shift toward more efficient energy transfer in cordless tools. This technology represents a fundamental change in how energy moves from the cell stack to the tool’s motor, moving beyond the limitations of traditional interconnect designs.
How Tabless Technology Improves Performance
Tabless cells differ from standard designs by eliminating internal tabs that carry energy. This reduction in resistance creates more direct energy pathways within the battery. The result is more available power, faster charging, and cooler operation. The amount of stored energy remains the same, but the efficiency gains allow these batteries to sustain higher output levels without overheating. By maximizing the interior surface area for conduction, the design minimizes the distance electrons must travel, which reduces the thermal load on the cell chemistry during high-demand tasks.
Kobalt offers two sizes in this new lineup: a 4.0Ah pack and an 8.0Ah pack. The 4.0Ah model produces up to 2,400 watts, while the 8.0Ah unit generates 1,200 watts. These figures represent up to 40% more power than standard 24V packs. The company also claims these batteries provide the longest runtimes available for their respective capacities. This efficiency means a user can expect significantly longer operation on a single charge, particularly when using power-hungry tools like chainsaws or rotary hammers that typically drain batteries quickly.
Compatibility is a key selling point for Kobalt. The Ultimate Output TXP batteries work with the entire 24V Max lineup. This means existing users can upgrade without replacing their entire tool collection. The packs also feature updated charge indicator lights and come with a three-year warranty. Both packs carry a 3-year warranty, ensuring that users are protected against defects for a substantial period. This warranty coverage applies equally to the 4.0Ah and 8.0Ah models, providing peace of mind for both casual and professional users.
Who Should Buy the New Batteries?
The new batteries retail for $99 for the 4.0Ah size and $159 for the 8.0Ah version. Like all Kobalt products, they are exclusive to Lowe’s. The market for these batteries sits between casual DIY users and professional contractors. For someone who uses tools regularly on demanding jobs, the increased power and runtime offer a clear advantage. The higher wattage output allows for cleaner cuts and more consistent performance in heavy-duty applications where standard batteries might struggle to maintain voltage under load.
