Kobalt has introduced two 24V Max Ultimate Output TXP batteries using tabless cells: 4.0Ah and 8.0Ah packs. Kobalt claims up to 40% more power than its standard 24V batteries, but the available report does not provide independent test results or a direct comparison showing that Kobalt has caught up to Ryobi.
Kobalt has introduced two tabless 24V Max Ultimate Output TXP batteries, adding a 4.0Ah pack and an 8.0Ah pack to its cordless-tool lineup. The launch brings Kobalt into a battery technology already used by competitors including Ryobi, but the available information does not establish that Kobalt has caught up in overall performance: the headline comparison has no direct test data behind it.
The new packs are rated at up to 2,400 watts for the 4.0Ah battery and up to 1,200 watts for the 8.0Ah battery, according to Kobalt, as reported by Pro Tool Reviews. Kobalt says the packs provide up to 40% more power than its standard 24V batteries and offer the longest runtimes among its 24V batteries of the same capacity. Those are manufacturer claims; the source does not include independent runtime or output testing.
Pro Tool Reviews reports that the batteries are priced at $99 for the 4.0Ah pack and $159 for the 8.0Ah pack. They are sold through Lowe’s, where Kobalt tools are exclusive, and carry a three-year warranty. The packs work with Kobalt’s 24V Max lineup, according to the report, so owners can use them with existing compatible tools rather than waiting for a new battery platform.
The exterior includes updated charge-indicator lights, while the main change is inside the cells. The report says tabless connections reduce electrical resistance compared with conventional cell designs. That can help a battery deliver power with less heat, but it does not increase the pack’s voltage or stored energy capacity. The listed 4.0Ah and 8.0Ah ratings remain the capacity figures; tabless construction is presented as a way to use that energy more efficiently.
What Kobalt’s Tabless Packs Change
For Kobalt 24V owners, the practical news is an option to seek higher output and potentially longer runtime without replacing compatible tools. That may matter most to users who regularly run demanding equipment or push batteries hard, since the claimed reduction in heat and resistance is relevant under heavier loads. Occasional home users may see less reason to replace batteries that still meet their needs.
The launch also narrows a visible gap in Kobalt’s battery offering: major power-tool brands have been adding tabless designs, and Ryobi is among the competitors named in the source. But joining the same technology category is not proof of parity. A meaningful “catching up” comparison would require comparable tests of output, runtime, charging time, temperature, price and tool compatibility across specific Kobalt and Ryobi packs. Those results are not provided here.
The distinction matters for buyers deciding whether to spend $99 or $159 on a new pack. Kobalt’s stated power ratings and runtime claims offer a reason to investigate the batteries, but they do not show how much improvement a user will see with a particular tool or workload. Existing Kobalt users can weigh the upgrade against their current battery condition and usage rather than treating the launch as a required switch.

Tabless Batteries Reach Kobalt
Tabless cells have been appearing in power-tool batteries for several years. Pro Tool Reviews says Milwaukee introduced tabless cell connections with its Forge batteries more than three years before this Kobalt report, and that Ridgid, Metabo HPT and Ryobi have also added tabless products. Kobalt is therefore entering an established industry trend, not introducing the design.
In a conventional cell, internal tabs connect parts of the cell to carry current. The source describes tabless construction as expanding the pathways available for energy transfer and lowering resistance. In principle, that can reduce heat and support stronger power delivery or faster charging. The benefits depend on the battery and tool, however, and the report does not give comparative test results for Kobalt’s new packs against older Kobalt batteries or Ryobi models.
Kobalt’s lineup is positioned toward do-it-yourself users and entry-level prosumers, according to the source. Its new batteries remain within the existing 24V Max platform. Pro Tool Reviews also raises the possibility of future tools designed around the higher-output packs, pointing to Kobalt’s XTR line, but reports no confirmed tool announcement.
“The batteries deliver up to 40% more power compared with standard 24V packs.”
— Kobalt, as reported by Pro Tool Reviews
Performance Claims Need Testing
The report does not give an announcement date, independent test results, charging times, measured temperatures or runtime figures for the new packs. It also does not identify which tools or test conditions support Kobalt’s up to 40% power increase and longest-runtime claims. “Up to” describes a maximum claim, not a guaranteed gain in every tool or task.
Most importantly, the source does not compare these Kobalt batteries directly with specific Ryobi tabless models. It offers no matched tests of output, runtime, charging, price or warranty across the two brands. The question of whether Kobalt is “catching up” therefore remains a broad interpretation, not a confirmed performance finding. Kobalt has also not, in the material provided, confirmed new tools developed specifically for the packs.
Watch for Tests and Tool Launches
The immediate next step for buyers is to check product listings and compatibility details for their particular Kobalt 24V Max tools, then compare independent testing as it becomes available. Results under similar loads would help establish whether the claimed output and runtime improvements translate into noticeable gains over standard Kobalt batteries and competing Ryobi packs.
Any future Kobalt tools designed to take advantage of tabless batteries would be a separate development. Pro Tool Reviews suggests that new high-output tools could follow, but reports no confirmed products or release dates. Until Kobalt announces them or comparative tests appear, the confirmed development is the battery launch itself—not a demonstrated overall lead over Ryobi.
Key Questions
Has Kobalt caught up to Ryobi?
The available report does not prove that. Kobalt has introduced tabless 24V batteries, a technology also used by Ryobi, but it includes no direct performance comparison between the brands.
What new Kobalt batteries were reported?
Kobalt introduced a 4.0Ah and an 8.0Ah 24V Max Ultimate Output TXP battery. The report lists prices of $99 and $159, respectively, and says both carry a three-year warranty.
What does tabless battery technology change?
According to Pro Tool Reviews, tabless cell connections reduce electrical resistance, which can help limit heat and support power delivery. They do not, by themselves, raise the battery’s voltage or amp-hour capacity.
Will the new batteries work with existing Kobalt tools?
The report says the packs are compatible with the Kobalt 24V Max lineup. Owners should still check the listing or product documentation for their specific tool and battery before buying.
Are the claimed power and runtime gains independently verified?
Not in the source material. Kobalt’s claims include up to 40% more power than standard 24V packs and the longest runtime among same-capacity Kobalt batteries, but the report provides no independent test results or detailed test conditions.
