Are Milwaukee M18 and M12 batteries interchangeable?
No. M18 batteries fit M18 tools only, and M12 batteries fit M12 tools. Many users run both platforms side by side.
What is Milwaukee FORGE?
REDLITHIUM FORGE is Milwaukee's latest battery technology: more power, faster charging and longer life than standard packs.
Which battery size should I buy?
A higher Ah rating (for example 5.0Ah, 8.0Ah or 12.0Ah) means longer runtime and, on FORGE, more power - ideal for demanding tools.
