Hi Stacy! Our M12™ Heated Jackets utilize our M12 batteries.
Yes... All m18 chargers charge all m18 batteries
I’ve had no issues with my 9 amp/hours. The only batteries i’ve had stop working are the ones I didn’t charge for 2 or more years, they just die and don’t charge
Hi there! You can use any M18 battery on any of our M18 products.
Hi Mattie! You can use any M18 battery on any M18 tool.
Hi there! You will typically get longer runtime with a larger battery. Our largest M18 battery is our M18 REDLITHIUM™ HIGH OUTPUT™ HD12.0 Battery Pack (48-11-1812).
You get longer run time with a 9.0 Amp-Hour battery than a 3.0 Amp-Hour battery. Higher ah batteries are better suited for "high demand" tools like a leaf blower or any tool that generally stays on/in use for longer periods of time.
No fan in battery!
