Hychika batteries

[speccy]

I have a Hychika leaf blower, its so dam good but one of the 4.0ah batteries has failed. Well it wont charge at all and the batt test button will not light up.

I was considering taking the pack apart and replacing the 18650 cells, any advice? Not done this before i believe i need a spot welder. Anyone out here know of a service where they repair or done it yourself?

Make sure the 18650's are genuine capacity ones, Torchy sells genuine ones. You can make a spot welder using a car battery and a heavy duty relay. You can also solder to the end caps, using plumbers flux, in place of multi-core electronic solder, providing you clean it off well, after soldering.

But if you solder be very careful not to overheat the battery cells while you do it, hence the spot welding recommendation.

worth placing battery and charger in a warm house for 24 hrs
also try charging another battery or use another charger iff you have the choice
do the charger lights work ok??
