Lowe’s has cut the Craftsman 20V tabless 6Ah battery starter kit to $99, half the $199 price that Amazon and Acme Tools still list, with the sale running through July 15, 2026. The kit bundles the new Craftsman Advanced 6Ah tabless lithium-ion battery with a basic charger. A discount this steep, this soon after launch, is unusual, and it is a useful window into two things at once: what tabless battery technology actually changes inside a pack, and how to judge whether any battery promotion is a real deal. The value of any deal comes down to the same discipline as valuing battery promotions: know what the cells deliver and what the baseline price per amp-hour really is.
What Makes a Tabless Cell Different
A conventional cylindrical cell, like an 18650 or 21700, is a wound jelly roll with a thin metal tab welded to each electrode. Those tabs carry current to the terminals, and under heavy draw they become a bottleneck: resistance builds, heat rises, and voltage sags. A tabless cell removes the bottleneck by letting the current collector foil itself carry current to the cap, or by integrating many contact points along the roll. The result is lower internal resistance, less heat, higher sustained discharge, faster charging, and typically more charge cycles over the pack’s life.
Craftsman describes the new battery as built for DIYers who always think ahead and calls it a true project powerhouse. Marketing aside, the tabless construction is a real engineering change, the same approach that powers Dewalt’s PowerStack packs and Bosch’s first 18V tabless battery.
For a DIY-focused brand, tabless cells matter because DIY tools get abused in bursts: a saw that stalls, a grinder run until the pack is hot, a battery left on the charger overnight. The lower resistance of a tabless pack shrugs off those habits better than a conventional pack, which is why Craftsman leads its V20 lineup refresh with the technology rather than a new tool.
Better cells do not rewrite the care rules, though. The truth about cordless power tool battery care has little to do with the memory effects that modern packs do not exhibit, and a tabless pack still wants partial discharges, cool storage, and a charger that matches its chemistry.
Why Battery Prices Are Falling Right Now
A $100 price drop on a starter kit a few months after it started shipping is surprising enough that the deal report called it shocking. The market context explains a lot. Battery pricing is in a broad slide: Metabo HPT’s tabless multivolt 4/8Ah battery is sitting at $119 at Lowe’s, Ego batteries are roughly half off, and the daily ads are full of buy-a-tool-get-a-battery promotions. Even Dewalt’s 8Ah tabless pack sold for less than $99 shortly after its release, and Ryobi’s 4Ah tabless battery with charger plus a tool has been bundled at $135.
Theories for the crash include an EV slowdown that freed up cell supply, tariff pricing unwinding, retailers clearing stock, and simple overproduction. For buyers the effect is the same: high-capacity packs are suddenly affordable, and the promotions need checking against a per-amp-hour baseline instead of a headline price.
The discount timing matters as much as the depth. Starter kits are the entry point for a platform, and retailers use them to pull in buyers who will spend on bare tools later. Pricing a 6Ah starter at $99 sends a clear signal about where Craftsman wants to sit against Dewalt and Ryobi, both of which have pushed tabless packs into the same price band.
The same lithium cells flow into tool packs and into whole-home storage, and a detailed home battery backup system case study shows how storage pricing moves across the whole market. When cell supply loosens, both shelves get cheaper at once.
How to Value a Battery Starter Kit
The working rule of thumb in the 18V class is that normal pricing runs about 4 amp-hours per $50, or $12.50 per amp-hour. Tabless construction adds a small premium, a budget brand shaves a little off, and a bundled charger adds $30 to $50 of real value. Run the numbers on the $99 kit and the picture changes fast.
- Price per amp-hour: $99 divided by 6Ah comes to $16.50 per Ah.
- The same kit at full price: $199 divided by 6Ah is $33 per Ah, more than double.
- The 3Ah starter kit at $129 works out to $43 per Ah, the worst value on the board.
- Against the 4Ah baseline of $12.50 per Ah, the sale kit carries a premium of about $4 per Ah.
- Count the charger: subtract $30 for the charger and the pack itself costs about $69, or $11.50 per Ah, which lands under the baseline.
The $99 kit is close to the normal baseline once the charger is counted, and the $199 list price is the outlier. Sales that look dramatic are often just returning the price to something reasonable.
How the current deals compare
| Kit | Capacity | Price | Price per Ah | Read on the deal |
|---|---|---|---|---|
| Craftsman 6Ah tabless starter, Lowe’s sale | 6Ah | $99 | $16.50 | Near baseline with charger included |

| Craftsman 3Ah starter, Lowe’s | 3Ah | $129 | $43 | Poor value per amp-hour |
| Metabo HPT multivolt 4/8Ah, Lowe’s | 4Ah at 36V, 8Ah at 18V | $119 | From $14.88 | Solid dual-voltage value |
| Ryobi 4Ah tabless, charger, plus tool, Home Depot | 4Ah plus tool | $135 | Varies with tool value | Good if the tool is needed |
| Dewalt 8Ah tabless, post-launch sale | 8Ah | Under $99 | Under $12.38 | Below the baseline |
Craftsman’s retail strategy has shifted repeatedly since the sale of Craftsman tools to Stanley Black and Decker, which planted the brand’s V20 lineup at Lowe’s. That history explains why the brand’s deals land at a different retailer than its rivals.
Voltage, Compatibility, and the Rest of the System
A tabless pack still has to match the platform. The Craftsman kit is V20, the 20V Max class, so it works with V20 tools and chargers. Most tools in the class accept newer packs, but high-capacity packs are sometimes physically longer, so check that the pack seats in the tool and the case closes.
Charger compatibility is the part buyers skip. A basic charger that comes with a starter kit fills a 6Ah pack slowly, often in two hours or more, while a rapid charger can cut that to under an hour. The charger in the box matters if the pack is the crew’s only one, so check its output rating before relying on it for a full day of work.
Platforms are living systems, and how cordless power tool battery systems evolve decides whether today’s deal works with next year’s tools. Voltage transitions, compatibility, and battery management all matter more than the color of the plastic.
Before You Buy: A Checklist
Use a short checklist before any battery promotion goes into the cart.
- Confirm the platform matches your tools. V20, 20V Max, and 18V class labels are not interchangeable.
- Compute price per amp-hour and compare it with the $12.50 baseline.
- Note the sale end date. The Lowe’s price holds through July 15, 2026, and deals like this rarely repeat at the same depth.
- Value the charger. A starter kit with a charger is worth more than a bare pack at the same price.
- Check warranty and return policy before opening the clamshell.
- Think about future tools. Tabless packs pay off most in high-draw tools like saws and grinders.
Bundles that ship with tools
A bundle like Ryobi’s 4Ah tabless battery, charger, and a tool at $135 changes the math. Price the tool at its normal street value first, then see what the battery effectively costs. If the battery portion lands near $12 to $15 per amp-hour, the bundle is fair. If the tool is one you do not need, the bundle is just a battery at a worse price.
Packs have gotten bigger and cheaper over time, and the broader cordless power tool battery evolution story shows why capacity upgrades keep landing at lower prices.
Capacity Planning for Real Work
What does 6 amp-hours actually buy? Roughly double the runtime of a 3Ah pack, and more importantly, sustained current for high-draw tools. A tabless 6Ah pack runs a circular saw or reciprocating saw harder before voltage sags, which means fewer stalls and less heat.
Crews that plan around high-capacity battery packs can work a full day without a charger visit, and the same logic that makes a 15Ah pack a site changer makes a $99 6Ah starter a sensible first step. For a homeowner or a small crew, the practical test is simple: does the pack finish the task without a recharge, and does it still hold voltage at the end of a hot afternoon?
