Milwaukee M18 Battery

Nuts and Bolts:

  • Good Battery: Yes
  • Super High Tech: No
  • Aftermarket Comparables: Yes for less!

The Milwaukee M18 Battery (RedLithium) is the newest “technology” out of Milwaukee tools. The RedLithium technology comes with the M12 and M18 tools (including Fuel and Brushless power tools).

The Milwaukee M18 18-Volt Lithium-Ion XC Battery Pack (battery part number 48-11-1828, 48-11-1815, and or N5.4330) comes in either a 1.5Ah, 3.0Ah or a 4.0Ah. The battery cells used are typically either Samsung, LG or Sanyo cells (all of which are perfectly good cell providers. Take a look at the OEM and the aftermarket Milwaukee M18 Battery and then let’s analyze both batteries. 

Both of these battery packs are constructed in the same manner and will act and operate the same and will charge on the same original charger. Both versions have a battery fuel gauge, slide pack design, an intelligent circuit board, an integrated welded frame, a cell separator, lithium ion cells, and a impact and vibration rubber to provide battery pack protection during usage.

Both batteries are 18V and 3.0Ah and both are optimized to operate in temperatures below 0 degrees farenhight and both have integrated power management circuits to protect against over-voltage and under-voltage conditions and maximize battery life between charges, minimize charging times, and improve overall battery life.

As I said above both batteries have:

  • 3.0 Amp hour – 54 Watt hour battery
  • High Current Discharge – Increased power and performance
  • Equivalent run-time with 40% less weight than an 18V NiCd battery
  • LITHIUM-ION battery delivers long life and run time with fade-free power
  • Fuel gauge onboard: Displays remaining runtime for less downtime
  • Integrated Overload Protection – Prevents user from damaging their cordless power tool
  • Temperature Management System – Keeps battery in ideal temperature range to provide maximum life
  • Individual Cell Monitoring – Ensures optimal charge and discharge for maximum life
  • Discharge Protection – Prevents cell damage from over-discharge
  • Integrated weld frame
  • Offers long-lasting performance and durability
  • Circuit Intelligence: Provides optimized performance and overload protection using total system communication between tool, battery and charger
  • Delivers fade-free power in extreme jobsite conditions
  • Versatility: Powers more than 40 Milwaukee M18 cordless power tools
  • Compatible Chargers: M18/M12 Multivoltage (48-59-1812), M18 AC/DC (2710-20)
  • MFG Model # : 48-11-1828
  • MFG Part # : 48-11-1828, 48-11-1815, and or N5.4330

So what is the difference? Price – the with the aftermarket version you will save yourself at least $30!
