Owned and used two cordless drills for years.
Eventually, the batteries would not hold a charge.
Purchased new batteries from a popular hardware store and more batteries from a popular online company. The batteries failed. Wasted time and money by the hardware store and online company.
Found MTO Battery Repair Company on the internet. Sent two different sets of batteries to be repaired. The batteries were repaired and sent back in a professionally packed parcel. Sent all the rest of my batteries for repairs.
Dependable quality work by MTO!
