Details
The Milwaukee M12 REDLITHIUM XC4.0 Battery 2-Pack (48-11-2442) gives you two 4.0Ah extended-capacity packs for the M12 12V system — long runtime, even in sub-zero temperatures, with REDLINK Intelligence to protect against overload and over-discharge. Compatible with most M12 tools, and backed by a 3-year warranty.
Why it's a smart pick
- Extended runtime — 4.0Ah (48 watt-hours) per pack for more work between charges.
- All-weather — fade-free power in extreme conditions with REDLINK overload protection.
- Two packs — keep one charging while you work; recharges in about 60 minutes on a rapid charger.
Is this the right battery for you?
Ideal for M12 users who want more runtime than a compact pack for tools like drills, ratchets, and heated gear. Note: M12 batteries fit M12 tools only — they are not compatible with M18 tools.
