Frequently Asked Questions
Q: What Kobalt 24V Max tools are compatible with this battery?
A: This battery fits 14-plus Kobalt 24V Max tools including: KCS 6524B-03 circular saw, KCW 5024B-03, KDS 124B-03 drill, KDSA 124-03, KHD 524B-03 hammer drill, KIW 3824B-03 impact wrench, KJS 324B-03 jigsaw, KMC 124B-03, KRAIW 124B-03, KRH 124B-03, KRS 124B-03 reciprocating saw, KRS 1824B-03, KRW 124B-03, KXCS 124B-03, and KXRS 124B-03.
Q: What Kobalt OEM battery part numbers does this replace?
A: This 6.0Ah battery replaces 7 Kobalt 24V Max OEM battery part numbers: KB624-03 (6.0Ah), KB524-03 (5.0Ah), KB424-03 (4.0Ah), KB224-03 (2.0Ah), KB124-03 (1.5Ah), 0673802, and 1051230. It is a direct upgrade from lower-capacity packs — a 6.0Ah provides 4 times the runtime of a 1.5Ah KB124-03.
Q: How long does the 6.0Ah battery last on Kobalt 24V tools?
A: Runtime depends on the tool. Light-duty use with a drill or impact driver gives hours of intermittent work. A circular saw under continuous cutting drains faster but still delivers significantly more cuts than a 2.0Ah or 4.0Ah pack. The 6.0Ah capacity provides roughly 4 times the runtime of the KB124-03 (1.5Ah) and 3 times the KB224-03 (2.0Ah).
Q: Which Kobalt chargers work with this battery?
A: This battery charges on Kobalt 24V Max chargers including the KRC 2490-03 and KRC 2404-03. A full charge takes approximately 60-90 minutes depending on the charger. The 2-pack lets you charge one battery while using the other.
Q: What is NOT compatible with this Kobalt 24V battery?
A: This battery is for the Kobalt 24V Max platform only. It is NOT compatible with Kobalt 40V or 80V outdoor tools, or any other brand's cordless system (DeWalt, Milwaukee, Makita, etc.). Always verify your tool says 24V Max on the label and accepts KB-series batteries before ordering.
Q: How long does it take to charge the 6.0Ah battery?
A: Charging takes approximately 60-90 minutes on Kobalt 24V Max chargers (KRC 2490-03 or KRC 2404-03). The 2-pack means zero downtime — swap batteries and keep working while the depleted pack recharges.
Q: What is included in the package?
A: The package includes 2 x 24V 6.0Ah lithium-ion replacement batteries for Kobalt 24V Max tools and a user manual. Batteries are brand new with blue housing. Free shipping with 24-hour dispatch and 1-6 day delivery.
