Kobalt 24 Volt -12in String trimmer ( Battery and Charger not Included)

What It Is

This is a Kobalt 24V battery and charger kit designed for the 12-inch string trimmer model, intended for users who already own the trimmer but need a replacement or spare power source. It does not include the trimmer itself.

Fitment & Compatibility

Before buying, confirm your trimmer model number (look on the trimmer body or manual) to ensure it matches Kobalt’s 24V platform. This kit is compatible only with Kobalt 24V tools that use the same slide-in battery interface—not with older 18V or 40V Kobalt models. Measure the battery compartment: the included battery is a standard 2.0Ah or 4.0Ah pack (check listing for exact amp-hours). If you have a different brand (e.g., Ryobi, DeWalt), this will not fit. For third-party compatibility, verify the battery’s voltage and terminal shape match your existing charger—this kit is OEM, so no adapter needed.

Key Things to Know

• Quality: Rated 4.4/5 from 174 reviews—generally reliable, but some users report shorter runtime than expected with 2.0Ah batteries on heavy grass.
• Installation: Trivial—slide battery into trimmer until it clicks. No tools required. Charger plugs into standard 120V outlet.
• Gotchas: Battery and charger are sold as a kit; if you only need a battery, check if a standalone option is cheaper. The charger may not work with older Kobalt 24V batteries (pre-2020) due to slight design changes.
• Runtime: Expect 15-25 minutes of continuous trimming per charge, depending on grass thickness and trimmer speed setting.

Should You Buy It

Buy this if you need a backup battery and charger for your Kobalt 24V string trimmer and want OEM reliability without hunting for third-party options. Skip it if you already have a compatible Kobalt 24V charger—then just get a standalone battery for less.
