• Power tool replacement lithium battery BL1830 BL1840 BL1850 Lithium-Ion battery 
• The 18volt lithium ion battery that widely used in power tools 
• The voltage 18V, capacity can be 3AH, 4AH and 5Ah in the same case.
• The 18V Lithium-Ion battery charges faster and works longer than standard lithium-ion batteries, giving you and your cordless tools unmatched performance and productivity to take on the most demanding applications.
• The 4.0 Ah battery combines more run time (35% more run time per charge than the BL 1830 battery) with a category-leading charge time of only 40 minutes, so it spends more time working and less time sitting on the charger.
• For added convenience, it also features an L.E.D. charge level indicator to monitor battery charge.

Cost Performance

♦ Long-run Cost: LiFePO4 battery could work at 60°c, with long life 5-10 years.

♦ Smaller Space: 1/3 of the lead acid battery.

♦ Low Maintenance Cost: maintenance free, centralized monitoring and module installatin also to reduce cost for transportation.

♦ Safety Cost: stable discharge platform to avoid euipmet exception.

♦ Save Electricity Power: with same capacity, LiFePO4 battery is more powerful hank lead acid battery, and could support longer.
