This bundle pairs the Milwaukee 48-59-1862S M18 REDLITHIUM HIGH OUTPUT XC 6.0Ah Battery 2-Pack Starter Kit with the Milwaukee 48-11-1850R M18 REDLITHIUM XC5.0 Oil & Solvent Resistant Battery — turning a two-battery starter kit into a three-battery M18 lineup, all charged by the one included charger. Model Numbers: 48-59-1862S (HIGH OUTPUT XC6.0 2-Pack Starter Kit), 48-11-1850R (XC5.0 Oil & Solvent Resistant Battery).

The 48-59-1862S kit includes two M18 REDLITHIUM HIGH OUTPUT XC6.0 battery packs and an M18 charger. HIGH OUTPUT XC6.0 delivers 50% more power and runs 50% cooler than standard M18 REDLITHIUM XC packs, with REDLINK Intelligence overload protection, an onboard fuel gauge, and compatibility with 150+ M18 solutions. Each pack measures 3.22"H x 3.30"W x 5.46"L, weighs 2.30 lbs, and carries a 3-year battery warranty.

The bundled 48-11-1850R adds a standard-format M18 REDLITHIUM XC5.0 battery built with a resistant housing for increased protection against exposure to common oils, greases, and solvents found in automotive and manufacturing environments. It delivers the same 2.5X-more-runtime, 20%-more-power performance as a standard XC5.0 pack, with the same REDLINK Intelligence, onboard fuel gauge, and compatibility across 200+ M18 solutions.

Good fit for anyone already running Milwaukee M18 tools who wants more batteries in rotation without a second charger — especially useful for shops or job sites where a battery is exposed to oils and solvents and a resistant-housing pack is worth having on hand.

Two Batteries Become Three

This bundle turns Milwaukee's HIGH OUTPUT starter kit into a three-battery M18 lineup without buying a second charger.

• Who it's for: M18 platform owners who want more batteries in rotation, especially anyone whose work exposes batteries to oils, greases, or solvents.
• Why it stands out: It combines two high-power HIGH OUTPUT XC6.0 packs for your most demanding tools with a specialty resistant-housing XC5.0 for harsher environments — all on one charger.
• Worth knowing: The bundled 48-11-1850R is currently a Tool Nut promo item (promo ID MKE607, running through 11/1/2026) — it's included here at that promotional price, so bundle economics may shift once that promo ends.

• What's included in this bundle? Two M18 REDLITHIUM HIGH OUTPUT XC6.0 battery packs, one M18 Charger, and one M18 REDLITHIUM XC5.0 Oil & Solvent Resistant Battery.
• Do I get a charger with this bundle? Yes — one M18 Charger is included (from the 48-59-1862S starter kit) and charges all three batteries in the bundle.
• What makes the resistant battery different from a standard XC5.0? It has the same 5.0Ah capacity and performance as a standard M18 REDLITHIUM XC5.0 pack, but with a housing built to resist exposure to common oils, greases, and solvents — useful in automotive and manufacturing environments.
• Will these batteries work with my other M18 tools? Yes — the HIGH OUTPUT XC6.0 packs work across 150+ M18 solutions and the XC5.0 resistant battery works across 200+ M18 solutions.
