Milwaukee RED Lithium Forge 8.0a hr works all day

The Milwaukee RED Lithium Forge 8.0amp hour battery allows me to operate both my 1/2 drill and Orbital sander for an 8 hour day without needing to change batteries. This is much easier to manage batteries when they have the power to last all day, I have eneough batteries to use the same battery every 3rd day. Excellent quality product at a reasonable cost

Real Forge

These are actually legit Forge batteries as far as I can tell. Gone through all the checks I know of to discern real from fakes, and these pass every test I know of. Plus they run my miter and circ saws at least 10-15% higher rpm... high enough you can pick up a difference in pitch over standard XC5.0's. How they're selling them ~80 bucks less than Home Depot I have no clue, but I'll take it... This is my second purchase of this battery over two months, and both were identical aside from the dat of manufacture on the bottom. One was Sept 2025, the other April 2025. "Mass" is the seller you want; I can't verify other sellers

Great Walmart Service, Powerful Forge Battery

Walmart made this purchase easy from start to finish. Ordering, shipping, and updates were all handled smoothly, and they offered the best price compared to other retailers. I'm a big fan of Milwaukee tools, but their battery prices can be steep. Walmart had the most competitive deal that day, which sealed the decision. • ⭐⭐⭐⭐⭐ Walmart's service and value • ⭐⭐ Milwaukee's battery pricing • ⭐⭐⭐⭐⭐ Forge series performance I own multiple drill motors, a chainsaw, and several batteries, but this Forge battery is a game‑changer. I'm excited to use it in my brushless drill mounted to a modified ice auger, and I know the chainsaw will be throwing chips with serious power.
