Why This Deal Is Worth It
Batteries are the single most expensive part of any cordless platform, and MAX Output packs sit at the top of the RIDGID lineup. Getting two 4.0Ah MAX Output batteries plus a charger for $79 is essentially paying bargain bin prices for premium power.
MAX Output is not just a bigger number on the label. These packs deliver up to 2X more power and up to 3X more runtime than a 1.5Ah lithium ion battery, which is the difference between a saw that pulls through a cut and one that bogs down halfway.
The compact size is worth noting too. A lot of high capacity batteries turn a drill into a club, but these stay small enough to keep the tool balanced and cut down on arm fatigue during long sessions.
Then there is the Lifetime Service Agreement. Register within 90 days of purchase and RIDGID covers batteries, tools, and chargers for free parts and service for life. On a $79 battery kit, that alone makes this a hard deal to beat.

Who This Is Best For
Anyone already running RIDGID 18V tools should jump on this. If you are sharing two old batteries across a drill, an impact driver, and a circular saw, adding two MAX Output packs fixes the bottleneck in one purchase.
It fits the garage woodworking shop, the home renovation setup, and the contractor truck box. Small shop owners who cannot afford to stop and wait on a charger get the biggest immediate payoff.
This is also the cheapest possible entry into the RIDGID platform. Get the batteries and charger at $79, then pick up bare tools as your projects call for them. That is how you build a full cordless lineup without paying kit prices every time.
When This Deal Ends
Today only. This price ends September 2, 2026, and a battery kit discounted this hard will sell out well before the day is over.
