Will these fit my existing Ridgid 18V tools?

Yes. They work with all Ridgid 18V tools and chargers, and any Ridgid 18V battery works in the same tools.

Is the 2.0 Ah capacity enough?

It is fine for drills, drivers and lights. For circular saws, grinders or long run times, a larger Ridgid 18V pack is a better fit.

How long does charging take?

About 40 minutes on a compatible Ridgid 18V charger. The charger is not included.

How does it compare to the older R840086?

It is the same 18V 2.0 Ah class but about 10% lighter, which makes tools feel less nose-heavy.

Two R87002 2.0 Ah lithium-ion batteries and an operator's manual. No charger.

When is the price lowest?

Battery two-packs tend to dip during tool-and-battery promotions and holiday sales. The current best new price is $49.88 at eBay as of November 4, 2026.

Our take on the Ridgid 18V Lithium-Ion Battery

This is a two-pack of Ridgid's R87002 18V 2.0 Ah lithium-ion batteries, the compact packs that fit every tool and charger in the Ridgid 18V line. They charge in about 40 minutes and weigh roughly 10% less than the previous R840086 pack, so they suit drills, drivers and other light-to-mid duty tools. The best new price is $49.88 at eBay as of November 4, 2026, with two stores listing new stock.
