The advertised 8.0Ah capacity is significantly larger than many standard M18 batteries.

• 48-11-1840
• 48-11-1820

This broad compatibility makes them useful for users already invested in the Milwaukee ecosystem.

LED Charge Indicator

An integrated battery indicator allows users to quickly check remaining charge levels without attaching the battery to a tool.

This feature helps reduce unexpected downtime on job sites or during DIY projects.

Built-In Safety Protection

Worthmah includes multiple electronic protection systems designed to guard against:

• Overcharging
• Over-discharging
• Overheating
• Short circuits

These protections help improve operational safety and battery longevity.
