Will this fit my Kobalt 24V tools?

Yes. It is a genuine Kobalt 24V MAX pack and fits tools on that platform. It will not fit other brands or Kobalt's older 18V or 40V lines.

How long does a 2.0Ah pack run?

Runtime depends on the tool. Expect it to suit drills, drivers and light cutting, and to run down faster in high-draw tools like circular saws or grinders than a larger Kobalt pack would.

Is a charger included?

No. The package is the battery alone. You need a Kobalt 24V charger, which you likely already have if you own Kobalt 24V tools.

Is this a genuine Kobalt battery or a third-party one?

It is a genuine Kobalt-branded lithium-ion pack, not an aftermarket replacement. The retailer selling it is independent and not affiliated with Kobalt.

Should I buy this or a bigger Kobalt pack?

Choose this for lighter weight and spare-pack coverage on drills and drivers. Choose a higher-capacity Kobalt 24V pack if you run saws or grinders for long stretches and want fewer battery swaps.

Can I leave it on the charger?

Kobalt's 24V chargers are designed for their packs, but follow Kobalt's own guidance on storage and charging. Store the pack away from heat and out of direct sun.
