A two-battery starter kit for RIDGID's 18V cordless line: two 4.0 Ah MAX Output lithium-ion packs plus a compact charger. MAX Output packs talk to RIDGID brushless tools, and RIDGID rates them at up to 3X the runtime and 2X the power of its older 1.5 Ah battery. The 4.0 Ah size is a middleweight — more capacity than compact 1.5–2.0 Ah packs, lighter than 6.0 Ah and larger. It suits owners of RIDGID 18V tools who want longer runs without a heavy pack, and anyone adding spare batteries to a kit.

Owners of RIDGID 18V tools generally rate the 4.0 Ah MAX Output packs as solid everyday batteries with good runtime for their size. Complaints center on capacity limits under heavy load and on the charger being basic.
The RIDGID AC8609340SB is an 18V starter kit with two MAX Output 4.0 Ah lithium-ion batteries and a charger. MAX Output batteries communicate with the tool, which lets any RIDGID 18V Brushless Tool use the battery's full potential for more power and more runtime.
Compared to the 1.5 Ah lithium-ion battery (AC870015), the 4.0 Ah batteries provide up to 3X more runtime and 2X more power. The batteries are compact and lightweight, which reduces user fatigue.
The charger has a smart charging indicator that shows the battery's charge status. It is an energy-saving charger and uses maintenance charging to preserve battery life. It can also be mounted on a wall for storage. The kit is compatible with all RIDGID 18V tools and chargers.
