Milwaukee USB Battery Now Runs 20% Longer
The Milwaukee RedLithium USB 3.0 Ah battery delivers 20% more capacity for USB Rechargeable products. The updated batteries were released to retailers in May 2020, with a price tag only slightly higher than the original Redlithium USB batteries.
Features of Milwaukee USB 3.0 Ah Batteries
Currently, the following tools use the Milwaukee RedLithium USB platform and can achieve upgraded run-time with the new 3.0 Ah cell:

- Low-Profile USB Rechargeable Headlamp
- USB Rechargeable Pivoting Flashlight
- Rover USB Rechargeable Pivoting Flood Light
- USB Rechargeable Hard Hat Headlamp
- USB Rechargeable Rover Pocket Flood Light
- Beacon USB Rechargeable Hard Hat Light
- RedStick Digital Levels w/ Pin-Point Measurement
This is great news for anyone on the RedLithium USB platform or using any of these tools. Where the older model RedLithium USB featured a 2.5Ah capacity battery, the update jumps it up to 3.0Ah. The end result is a battery that runs for 20% longer on a charge.
As before, you can charge the RedLithium USB 3.0 cells in the tool or in a separate charger. Milwaukee optimizes RedLithium USB charge times with its hardware, so as to minimize downtime. It takes around two hours to fully charge this battery using either method. At a 2.1-amp charging rate, you also get at least an 80% charge in under 1 hour.
