ITS Expert Says

These Milwaukee 18V batteries are the lifeblood of all the entire heavy-duty Milwaukee M18 range of cordless tools. They have a battery state indicator and soft rubber protection.

Remember - with batteries the higher the Ah the longer the runtime... not more power! A 3.0Ah could last 30mins doing a task - a 5.0Ah could last 50 mins doing the same task - they both produce the same amount of power it's just that the 5.0Ah will last longer!
