PACK OF 4 MILWAUKEE M18 5.0 AH BATTERIES.

Contents of the 4-pack of Milwaukee M18 5Ah batteries

This economical pack includes four identical high-performance batteries to maximize your autonomy on the job site while making substantial savings compared to buying them individually.

Included in your order:

4x Milwaukee 48-11-1850 REDLITHIUM XC 5.0 Ah Battery

Each lithium-ion battery provides 5 hours of runtime on a standard drill/driver and features a 4-level LED indicator to monitor the charge level. Its robust construction includes a reinforced housing and a shock-resistant overmolded base that can withstand drops of up to 3 meters. REDLINK Intelligence technology ensures optimal communication with M18 tools and provides protection against overload, overheating, and deep discharge.

Advantages of the 4-Battery Pack

Substantial savings on multiple purchases

By choosing this 4-battery pack, you save approximately 15% to 20% compared to purchasing four individual batteries. This configuration represents the most cost-effective option for equipping a professional team or building up a sufficient reserve for large-scale projects.

Continuous rotation without stopping time

With four Milwaukee M18 5Ah batteries at your disposal, you maintain maximum productivity all day long. While two batteries power your tools, the other two recharge, ensuring an uninterrupted workflow even on the most demanding job sites.

Complete solution for professional teams

This complete Milwaukee battery kit is ideal for contractors equipping multiple workers simultaneously. Distribute one or two batteries per team member to standardize your tool inventory without compromising performance or managing multiple platforms.

Sustainable investment with proven technology

REDLITHIUM XC batteries offer up to twice as many recharge cycles as standard batteries, significantly extending their lifespan. This four-pack secures your investment for years of reliable service.

Recommended Additional Accessories

Optimize your investment:

Milwaukee M18/M12 Multi-Voltage Rapid Charger (48-59-1812)- Simultaneously charges M18 and M12 batteries, charging time 60 minutes for 5.0 Ah, intelligent temperature management. Sold separately.

Milwaukee M18 FUEL High Performance Tools- M18 FUEL drill/driver, M18 impact driver, M18 circular saw, all compatible with your new 5.0 Ah batteries.

Milwaukee M18 HIGH OUTPUT 6.0 Ah battery (48-11-1865)- Upgrade for ultra-demanding applications requiring maximum power, compatible with the same M18 system. Sold separately.

First Use

Optimal activation of your new Milwaukee M18 5ah batteries:

1. Initial load check

Before use, check the charge level of each battery by pressing the LED indicator button. Batteries are usually pre-charged to 30-40% at the factory, which is sufficient for testing but requires a full charge for optimal performance.

2. First full charge recommended

Place each new battery on a compatible Milwaukee charger and allow it to charge fully until the indicator light goes out, approximately 60 minutes. This initial full charge conditions the lithium-ion cells and maximizes their capacity from the start.

3. Compatibility test with your tools

Install a charged battery on each of your M18 tools to confirm a secure connection and proper operation. The REDLINK Intelligence system will automatically activate and optimize settings for each specific tool.

4. Establishing a rotation system

Label your four batteries with markers or numbered labels to facilitate rotation and track individual usage. This helps distribute wear evenly and maximize the overall lifespan of your pack.

Regular Maintenance

To maximize the lifespan of your Milwaukee M18 batteries:

After each use:

Remove the batteries from the tools once the job is finished to avoid passive discharge.

Wipe the contacts with a dry cloth to remove dust and debris accumulated during use.

Visually check the case for any damage, cracks, or deformations.

Load management:

Recharge the batteries as soon as the LED indicator shows 1 bar remaining or less, avoid repeated complete discharges.

Do not leave the batteries completely discharged for more than 48 consecutive hours.

Use only genuine Milwaukee chargers to preserve warranty and performance.

Recommended rotation:

Alternate between your four batteries regularly to even out the charge and discharge cycles.

Perform monthly inspections of all four units to detect anomalies early.

Record approximately the number of cycles per battery if used intensively for professional purposes.

Cleaning and Maintenance

Deep monthly cleaning:

Electrical contacts:Clean with a cotton swab lightly moistened with 70% isopropyl alcohol, dry completely before reuse. Never use harsh solvents, gasoline, or abrasive cleaners.

External casing:Wipe with a damp cloth and mild soap to remove grease, oils, and residue. Avoid immersion in water despite the water-resistant coating.

Ventilation vents:Use low-pressure compressed air to dislodge accumulated dust from the side cooling grilles. Keep the nozzle at least 15 cm away.

LED indicator:Check the LED display monthly by pressing the test button. If the display malfunctions, contact Milwaukee service.

Frequency: Light cleaning weekly in intensive use, thorough cleaning minimum monthly.

Precautions for Use

For your safety and the safety of your batteries:

Avoid significant shocks and falls:Although built to withstand harsh environments, repeated drops from heights greater than 3 meters can damage internal cells despite reinforced casing.

Never modify or open the batteries:Any attempt to disassemble the product will immediately void the warranty and may result in fire or explosion. Repairs should only be carried out by authorized Milwaukee service centers.

Keep away from sources of extreme heat:Do not expose batteries to temperatures above 60°C, including inside vehicles parked in the sun during summer or near radiant sources.

Use exclusively with compatible M18 tools:Forcing insertion into non-M18 tools or attempting to adapt them may result in short circuits and permanent damage.

Monitor for signs of abnormalities:Stop use immediately if the battery emits an unusual odor, excessive heat, visible swelling, or leaks. Isolate the defective battery in a non-flammable container and contact Milwaukee.

Storage Tips

Short-term storage (less than 2 weeks):

Keep batteries between 40% and 80% charge to preserve cell chemistry.

Ideal temperature between 10°C and 25°C in a dry place away from direct light.

Leave batteries on a shelf or in a PACKOUT case, avoid metal surfaces.

Long-term storage (more than 2 weeks):

Charge batteries to 50-60% before prolonged storage, the optimal level for cell preservation.

Check and recharge to 50% every 3 months to avoid damaging deep discharge.

Store in a climate-controlled environment between 15°C and 20°C with relative humidity below 60%.

Store in original packaging or insulated case for protection against moisture and dust.

Winter storage in Quebec:

If storing in an unheated garage or shed, insulate batteries in an airtight container with desiccant packets.

Avoid prolonged direct exposure to freezing temperatures below -20°C even if batteries tolerate -18°C in use.

Warm gradually to room temperature before use after cold winter storage.

Expected lifespan with proper storage: 3 to 5 years (500 to 1000 recharge cycles) depending on usage intensity and storage conditions.
