Which Milwaukee Charger Fits Your Battery Mix and Charging Routine?
Pick the 48-59-1812 for a mixed M12/M18 battery collection. Pick the 48-59-1806 for an M18-only station where staging up to six packs in a sequential queue matters. Neither model charges its staged packs simultaneously.

The buying question
Should you choose a charger that covers both M12 and M18 packs, or a six-bay M18 charger for organizing several M18 packs?
The 48-59-1812 covers both battery platforms and charges sequentially; the 48-59-1806 is M18-only and can stage up to six packs in its sequential charging rotation.
Quick verdict
Choose Milwaukee M18 & M12 Multi-Voltage Charger 48-59-1812 if
- You use both Milwaukee M12 and M18 batteries and want one charger model that accepts both platforms.
- You usually charge one or a small mix of packs rather than stage as many as six M18 packs.
Choose Milwaukee M18 Six Pack Sequential Charger 48-59-1806 if
- Your batteries are M18 and you want up to six M18 packs placed in the charger for sequential charging.
- The skip control and six-bay layout are useful for organizing a rotating group of M18 packs.
When the recommendation changes
- If you add M12 tools or batteries, the 48-59-1812's documented platform coverage becomes more useful.
- If you regularly stage several M18 packs together, the 48-59-1806's six-bay queue may fit that routine better.

Limitations
- Both models charge sequentially; this comparison does not claim simultaneous charging or compare measured charge speed.
- The 48-59-1812 product-page graphic identifies a bay for each battery platform. The manuals and product pages do not establish a universal workday charging schedule for a given battery mix.

Questions shoppers ask
Does the 48-59-1812 charge M12 and M18 batteries at the same time?
It accepts both battery platforms, but Milwaukee describes its charging as sequential. The product comparison graphic lists one bay for M12 and one for M18; that does not mean both packs charge simultaneously.
Does the 48-59-1806 charge six M18 batteries simultaneously?
No. It can stage up to six M18 packs and charges them in sequence. Its manual also describes a skip control for moving to the next pack.
