sparky on Jul 16, 2016
BEST ANSWER: Depending where you are located Batteries Plus can rebuild these batteries but is usually about same a getting a new battery.Milwaukee has several repair centers all over the US if under warranty or just needing a new one. I have had good service withCPO purchasing a recon set for just a small amount more than a battery replacement and getting 2 batteries and a charger and a tool. 
I have a red lithium 4.0 battery that's malfunctioning where can I get it rebuilt if possible

BEST ANSWER: Thanks for your question.
DO NOT under any circumstances purchase or buy a rebuilt Lithium-ion battery from anyone.� Also do not purchase aftermarket Lithium-ion batteries.� All Lithium-ion batteries are subject to causing fires if not handled carefully and charged correctly.� For example, low quality (cheap brand xxx) Lithium-ion batteries were the cause of recent Hoverboard fires that made national news.� I am one of the fire investigators that investigated a Million Dollar house fire in Nashville, TN caused by a Hoverboard.� I also investigated two other non-hoverboard Lithium-ion fires the same month.� That being said, I own and use several devices that use Lithium-ion batteries.� They include Milwaukee M18 REDLITHIUM XC 18V 5.0 AH and M12 REDLITHIUM 2.0 batteries, Dell Lithium-ion computer batteries, drone Lithium-ion batteries, and Hoverboard Lithium-ion batteries manufactured by Samsung. � Lithium-ion batteries are great (high power density) if purchased from a major well-known manufacturer and charged only with that manufacturer's Lithium-ion battery charger.� The batteries must not be exposed to high heat (summer temperatures inside a vehicle), excessive vibration or blunt force, overcharged or undercharged.� Overcharge can result from leaving the battery on the charger too long or using an aftermarket charger with poor voltage regulation.� Undercharge can also damage the battery.� Undercharge can occur when the the battery sits for several months without being charged.� They store best when charged to 2/3 capacity and not letting the battery capacity drop below the last bar of charge.� Again, I trust Milwaukee REDLITHIUM batteries.� I wear them in my Milwaukee heated jacket and use them in my tools. � Only charge Lithium-ion type batteries when you can keep an eye on them and never leave them charging overnight or when you are not at home.� It is better to be safe than sorry.� Thanks again for the question, I hope this helps. �
