About Garage Almanac

Garage Almanac is a reference site for people with a truck and a garage. We start with the question that costs the most wasted money and burned-out tools: does this battery fit that tool?

Our Mission

#

Cordless power-tool batteries are a mess of competing brands, voltages, and lookalike adapters — and a wrong “yes” can damage an expensive tool. We publish clear, source-checked compatibility facts: per-platform battery hubs, cross-brand adapter guides (with the real products that exist), and within-brand interchange answers.

What we cover

#

• Battery adapters: which cross-brand adapters exist, what they cost, and their limitations.
• Platform compatibility: which batteries fit which tools, by brand and platform.
• Interchange & legacy: mixing old and new packs within a brand, safely.

Every compatibility claim is backed by a cited source, and adapter listings link to real products. The reference is refreshed on a regular schedule.
