Good product!!

I haven't used these a lot yet. However, so far so good. Both charged up fine with no problems and worked just as well as the OEM batteries. Of course, with these types of batteries it can be a long time before you find out there are issues with short life span, but for the price this is a hard deal to beat.

After several full workdays using these JUNWOOD 4.0Ah 12V batteries, their performance holds up impressively. The increased capacity over the standard 2.0Ah packs means noticeably longer runtime, especially on high-draw tools like drills and impact drivers. They charge consistently without overheating, and fit snugly in all Dewalt 12V Max tools I tested, with no issues clicking into place or staying secure during use. The only minor drawback is that they’re slightly bulkier and heavier than lower-capacity packs, which may affect balance for precision tasks. Still, the trade-off is more than worth it for the extra juice they deliver. For anyone running multiple tools or working away from charging stations, this 2-pack is a practical and cost-effective upgrade.
