Maxmech ULB 20-4.0Ah Battery 4Ah

The Maxmech ULB 20-4.0Ah Battery is a higher-capacity Lithium-Ion battery designed for the Maxmech 20V cordless tool system. With 4.0 Amp-hours (Ah), it offers double the runtime of the 2.0Ah battery, making it ideal for more demanding tools and extended work sessions.

Key Features & Specifications:

• Model: ULB 20-4.0Ah
• Battery Type: Lithium-Ion (Li-ion) – Provides all the benefits of Li-ion technology: lightweight, no memory effect, slow self-discharge, and consistent power delivery throughout its discharge cycle.
• Voltage: 20V (often referred to as “20V MAX” or “20V Peak Voltage”) – This is the operating voltage for all tools in the Maxmech 20V cordless line.
• Capacity: 4.0 Amp-hours (Ah) – This is the key difference from the 2.0Ah battery. A 4.0Ah battery stores twice the energy, resulting in significantly longer runtime for power-hungry tools and less frequent recharging.
• Compatibility: Fully interchangeable with all Maxmech 20V cordless tools and chargers. This is a major advantage for users who own multiple Maxmech 20V tools.
• LED Fuel Gauge (Highly Likely): Like most modern cordless batteries, it almost certainly features an integrated LED indicator to display the remaining charge, allowing you to monitor power levels at a glance.
• Charging Time: While charging time will be longer than a 2.0Ah battery on the same charger, using a fast charger (which often comes with higher-end tools or can be purchased separately) can still charge a 4.0Ah battery relatively quickly.
• Protection Features: Includes built-in protection mechanisms against overcharging, deep discharging, overheating, and short circuits to ensure safety and prolong the battery’s lifespan.
