Makita 40V Max XGT 8.0 Ah Lithium-Ion Battery- Next generation ultra-high capacity battery designed with revolutionary XGT technology offering 288 Wh of maximum total energy and superior energy efficiency up to 60% more autonomy compared to 5.0 Ah batteries, equipped with an integrated LED indicator for precise monitoring of the state of charge, an ultra-sophisticated XGT electronic management system protecting against overload, overheating and over-discharge, with an ultra-robust reinforced, impact-resistant case resistant to extreme professional conditions and exceptional cold resistance down to -20°C for the most rigorous Quebec winters.

Advantages of the Makita 40V Max XGT 8.0 Ah Battery

Unmatched Maximum Battery Life- The exceptional 8.0 Ah capacity combined with the high 40V Max voltage delivers an impressive total energy of 288 Wh, offering the highest absolute runtime available in the Makita XGT range. This ultra-high capacity allows for full days of work without recharging, even with the most power-hungry XGT tools: up to 600 cuts in 2x4 timber with a circular saw, or 90 minutes of continuous grinding with a high-power angle grinder, completely eliminating interruptions for recharging on remote job sites, urgent projects, or continuous applications requiring absolute maximum productivity.

XGT Technology Superior EfficiencyThe next-generation XGT technology represents a revolution in the energy efficiency of professional high-voltage batteries, extracting up to 50% more usable energy from each stored watt-hour compared to previous high-voltage batteries. This exceptional efficiency translates into dramatically longer runtimes, minimized heat generation, significantly extended battery life, and consistent performance from the beginning to the end of each charge. This allows XGT tools to maintain maximum speed and high torque even under prolonged heavy loads, unlike previous batteries that gradually slow down.

Unrivaled and Exceptional Winter Performance- Cold resistance down to -20°C combined with an ultra-high 8.0 Ah capacity ensures optimal performance even during the harshest Quebec winters. Unlike standard batteries that lose up to 50% of their capacity in very cold weather, this XGT 8.0 Ah battery maintains exceptional runtime and power even at -20°C thanks to its sophisticated advanced thermal management and next-generation XGT cell chemistry specially developed for extreme climates, allowing Quebec professionals to work efficiently year-round without compromising performance.

Maximum Profitability InvestmentWhile this ultra-high-capacity battery represents a higher initial investment, its long-term cost-effectiveness is exceptional for professionals using high-power tools daily. The complete elimination of charging interruptions increases daily productivity by 15 to 25%, the extended lifespan thanks to XGT technology reduces replacement costs over 5 years, and the ability to work full days without multiple batteries simplifies logistics and reduces the total investment required for batteries for professional teams.

Regular Maintenance

Monthly Checks

• Inspect the XGT high-power electrical contacts and clean them gently with a dry cloth if necessary.
• Check the overall condition of the ultra-rugged reinforced case for cracks or damage.
• Test the LED indicator to ensure it is working correctly and accurately.
• Ensure that the XGT ventilation openings are not blocked by debris

Ultra-High Capacity Charge Management

• Recharge the battery before it is completely discharged to optimize its extended lifespan.
• Use only Makita chargers certified as compatible with the 40V Max XGT high power standard.
• Take advantage of the exceptional 60-minute fast charging to maintain maximum productivity
• Avoid leaving the battery completely discharged for extended periods.

Performance Monitoring

• Note any significant decrease in XGT's exceptional range or energy efficiency
• Carefully monitor the temperature during prolonged intensive use with ultra-powerful XGT tools.
• Immediately replace any battery that shows signs of swelling, leakage, or abnormal behavior.

Cleaning and Maintenance

Clean the exterior of the Makita XGT 8.0 Ah battery with a slightly damp cloth after use on dusty or dirty job sites, taking care to avoid getting water inside the new generation high-power XGT electrical connectors. Never use solvents, gasoline, or harsh chemicals that could damage the ultra-rugged reinforced casing or compromise the sophisticated XGT electronics.

For XGT high-power electrical contacts, use a pencil eraser or a dry cloth to gently remove any oxidation or metallic residue buildup that could reduce maximum power transmission. Ensure the contacts are completely dry and clean before inserting the battery into a tool or charger to prevent short circuits or performance loss that could affect XGT's exceptional energy efficiency.

Regularly inspect the sophisticated ventilation openings and use low-pressure compressed air (maximum 40 PSI) to remove any accumulated dust, sawdust, or debris. Never attempt to open the casing of the ultra-high-capacity XGT 8.0 Ah battery, as this will immediately void the 3-year warranty and irreparably damage the premium, next-generation, ultra-sophisticated XGT electronic management system.

Precautions for Use

Never expose the Makita 40V Max XGT 8.0 Ah battery to temperatures above 50°C, as this could damage the next-generation high-density lithium-ion cells and compromise the ultra-sophisticated XGT electronic system. While this battery is exceptionally cold-resistant down to -20°C, avoid extreme thermal shock by allowing the battery to acclimatize gradually when moving between very different temperatures—this is especially important for this premium ultra-high-capacity battery.

Avoid violent shocks, drops, and severe impacts that could damage the ultra-complex internal structure or the sophisticated XGT electronic protection system. Although the ultra-rugged, impact-resistant reinforced casing is designed for the most demanding professional use, the 2.0 kg weight of this ultra-high-capacity battery can cause significant damage if dropped from a considerable height.

Never use a battery that shows any signs of physical damage, cracks, bulges, or leaks. Due to its exceptional 8.0 Ah capacity, high 40V voltage, and impressive 288 Wh total energy, a damaged battery poses a significantly increased risk. If you notice any of these issues, stop use immediately, isolate the battery in a non-conductive container, and contact Polar Industrial Equipment for safe disposal advice.

Keep the battery away from flammable materials and never charge it near heat sources or in confined spaces without adequate ventilation. Never immerse the battery in water or any other liquid, even partially, as moisture ingress could short-circuit the highly sophisticated XGT electronic system and pose significant risks due to its high 288 Wh capacity.

Storage Tips

Store your Makita 40V Max XGT 8.0 Ah battery in a cool, dry place, ideally at a controlled room temperature between 15°C and 25°C, away from direct sunlight and excessive humidity. The ultra-sophisticated XGT management system is designed to protect the battery even during storage, but optimal conditions will further extend the lifespan of this exceptional, next-generation, premium ultra-high-capacity battery.

For extended storage of more than one month, maintain the battery at a charge level of approximately 40 to 60% rather than fully charged or completely discharged. This practice is particularly critical for the new generation XGT 8.0 Ah ultra-high capacity batteries, as it optimizes the preservation of the high-density lithium-ion cells and maintains the superior energy efficiency of XGT over the long term.

Use the original robust packaging or a reinforced protective case specifically designed for ultra-high capacity batteries to prevent accidental contact between the electrical terminals and metal objects. XGT 8.0 Ah ultra-high capacity batteries can deliver an extremely high current in the event of a short circuit, presenting a significant fire hazard due to their high energy capacity of 288 Wh.

Check and recharge the battery at least every 2 to 3 months, even if it is not in use. Although the XGT system minimizes natural self-discharge, ultra-high-capacity batteries benefit from periodic recharging to maintain optimal electrochemical health and ensure they are ready for immediate use with exceptional maximum XGT performance.
