Care and Usage

First Use

Activating your new Milwaukee FORGE battery:

  1. Initial inspection- Visually inspect the battery for any transport damage. Examine the electrical contacts and ensure they are clean and free of debris.
  2. Full charge recommended- Before first use, fully charge the battery for 80 to 120 minutes with a Milwaukee M18 charger. The LED indicator will display 4 illuminated segments when fully charged.
  3. Conditioning cycle- To optimize performance, perform 3 to 5 complete charge/discharge cycles during the first week of use. This calibrates the integrated management system and maximizes capacity.
  4. Compatibility test- Install the battery on your M18 tools to check for a secure connection. You should hear a distinct click when correctly installed.

Regular Maintenance

To maximize the lifespan of your Milwaukee FORGE battery:

After each use:

  • Remove the battery from the tool to prevent unwanted discharge.
  • Wipe the contacts with a dry cloth to remove dust and debris
  • Check the LED indicator to plan your next charge

Load management:

  • Recharge when the indicator shows 1 segment remaining
  • Avoid repeated full discharges which reduce lifespan
  • Do not leave the battery discharged for more than 48 hours.

Recommended rotation:

  • If you have multiple batteries, alternate their use for even wear.
  • Label your batteries with a permanent marker to track cycles
  • Inspect contacts monthly for corrosion or wear

Cleaning and Maintenance

Deep monthly cleaning:

  1. Electrical contacts- Clean with a soft pencil eraser or a dry, lint-free cloth. Absolutely avoid solvents, alcohol, or chemicals that will damage the protective coating.
  2. Outdoor enclosure- Wipe with a slightly damp cloth and mild soap. Dry immediately and completely before use or storage.
  3. Ventilation grilles- Use low-pressure compressed air (less than 40 PSI) to dislodge accumulated dust. Keep the nozzle at least 15 cm away.
  4. Visual inspection- Check for cracks, casing deformation, or signs of overheating. Any physical damage requires immediate replacement.

Suggested frequency:Light weekly cleaning in intensive use, complete monthly cleaning.

Precautions for Use

For your safety:

  • Avoid exposure to water- Although splash-resistant, immersion or prolonged exposure to moisture will permanently damage lithium-ion cells and void the warranty.
  • Never disassembleOpening the case poses a risk of short circuit and release of hazardous substances. Repairs should only be carried out by authorized Milwaukee service centers.
  • Operating temperature- Do not use if the battery temperature exceeds 70°C to the touch. Allow to cool for 30 minutes before recharging to avoid permanent damage.
  • Avoid violent impacts- Drops from more than 2 meters can crack internal cells even without visible external damage. Test performance after any significant impact.
  • Secure storage- Keep away from metal objects (keys, coins, tools) that could short-circuit contacts and cause a fire. Use a protective cap if available.

Storage Tips

Short-term storage (less than 2 weeks):

  • Optimal charge level: 40 to 60% (2 LED segments)
  • Ideal temperature: 15 to 25°C
  • Location: Dry place, away from direct sunlight
  • Verification: None required

Long-term storage (more than 2 weeks):

  • Mandatory charge level: 50% (2 LED segments)
  • Recommended temperature: 10 to 20°C
  • Humidity: Less than 60% relative humidity
  • Verification: Check the charge monthly, recharge if necessary
  • Recommended cycle: Perform a complete charge/discharge every 3 months

Winter storage in Quebec:

  • Never leave in an unheated vehicle during freezing temperatures.
  • Store in a heated garage or basement (temperature > 0°C)
  • Before using in very cold weather, preheat the battery to room temperature for 30 minutes.
  • After winter outdoor work, allow the battery to reach room temperature before recharging.

Expected lifespan with proper storage:5 to 7 years with 80% of original capacity maintained.

Our answers to your questions about the Milwaukee FORGE 8Ah Battery

How long does the Milwaukee 18V 8Ah battery last on a full charge?

Runtime varies depending on the tool used and the intensity of the work. On a standard drill/driver, expect approximately 1,200 to 1,500 holes of 25 mm drilled into hardwood.

On a circular saw, you can make up to 600 cuts in 2x4 lumber. An angle grinder will run for 90 to 120 minutes of continuous use.

For light tasks such as an impact driver, runtime can easily reach a full 8-hour workday. High-power tools such as chainsaws or rotary hammers consume more energy, providing 45 to 90 minutes of intensive use.

What is the difference between the Milwaukee FORGE 8Ah battery and a standard 5Ah battery?

Three major differences distinguish these batteries:

Capacity and runtime:

  • 8Ah provides 60% more energy than 5Ah
  • Allows 1.6 times more work without recharging
  • Ideal for intensive applications requiring long runtime

Technology and performance:

  • FORGE uses exclusive high-density cells
  • Superior thermal management reduces overheating
  • Extended lifespan (2000+ cycles vs 1500 cycles)

Size and weight:

  • 8Ah measures 13.7 cm vs 11.2 cm for the 5Ah
  • Weight: 1.2 kg vs 0.9 kg
  • Slightly bulkier but with excellent balance

Price:

  • 8Ah costs approximately 40–50% more
  • Investment justified for professionals
  • Better long-term runtime-to-price ratio

Is this battery compatible with all the Milwaukee 18V tools I already own?

Yes, universal compatibility is guaranteed across the entire M18 platform. This battery works with more than 250 different Milwaukee 18V tools, including drills, impact drivers, circular saws, grinders, work lights, jobsite radios, and specialized tools.

Any tool bearing the M18 logo or 18V Milwaukee marking accepts this battery without an adapter. REDLINK technology ensures optimal communication between the battery and the tool for maximum performance.

The only exception: Milwaukee 12V (M12) tools use different batteries and are not compatible.

  • Recommended temperature: 10–20°C
  • Check and recharge monthly

Québec winter protection:

  • Never leave in an unheated vehicle
  • Store at temperatures above 0°C
  • Pre-warm for 30 minutes before use in extreme cold

Consult the Maintenance and Use section above for complete detailed instructions.

Does this Milwaukee battery work properly in cold Québec winter conditions?

Yes, performance is maintained even in harsh winter conditions. The Milwaukee FORGE 8Ah battery operates effectively down to -18°C according to manufacturer specifications.

Lithium-ion cells specially formulated for cold climates retain significant capacity even at sub-zero temperatures. The REDLINK thermal management system automatically preheats the cells during the first seconds of use to optimize performance.

Winter use recommendations:

  • Store the battery at room temperature overnight
  • Keep it on you or in an inside pocket between uses
  • Pre-warm for 15–30 minutes before intensive outdoor work
  • Performance reduced by approximately 15–20% between -10°C and -18°C
  • Below -18°C, periodically bring the battery indoors to warm up

Cold climate advantages:

  • Extended lifespan (cold temperatures slow degradation)
  • Lower risk of overheating during intensive work
  • Ideal for winter construction, snow removal, and outdoor repairs

Extreme temperatures below -20°C are not recommended to preserve optimal longevity.
