  • Our take on the Kobalt 24-Volt Max 4.0Ah Lithium Battery KB 424-03

    The Kobalt KB 424-03 is a 24-volt max, 4.0Ah lithium-ion pack for the Kobalt 24V cordless line. It has an on-board charge indicator that reads whether the pack is on a tool or off, plus internal protection against overheating, over-discharge and over-charge. It recharges in about an hour on a compatible Kobalt charger, which is sold separately. It suits Kobalt 24V owners who want a mid-capacity pack for regular DIY and light trade work, and it competes with the brand's smaller 2.0Ah packs on runtime and its larger packs on weight.

    Questions and answers

    Does this battery fit all Kobalt 24V tools?
    Yes. Kobalt lists it as compatible with all Kobalt 24-volt max cordless tools. It will not fit other brands' tools.
    Is the charger included?
    No. The charger is sold separately. Recharge time is about one hour with a compatible Kobalt charger.
    How long does it run compared with the 2.0Ah pack?
    At 4.0Ah it holds roughly twice the charge of Kobalt's 2.0Ah pack, so expect about double the runtime in the same tool, at more weight.
    Can I check the charge while it's on the tool?
    Yes. The power indicator shows charge status whether the pack is attached to a tool or detached.
    What does the protection system do?
    Internal circuitry guards the pack against extreme temperatures, over-discharge and over-charge.
    Is it worth it over a larger pack?
    It is a middle option: more runtime than the 2.0Ah pack and less weight than the bigger packs. Choose it if you want a balance of both for regular DIY work.
    Where is the Kobalt 24-Volt Max 4.0Ah Lithium Battery KB 424-03 cheapest?
    At TaskHolt, for $68.74, as of our latest check.
