20 year old Mathmos Colour changing LED light with inductive charging and remote control. look like frosted pillar candles
battery dead not reading remote control commands properly. still kinda works on the charging plate
remove base with sharp knife
badly swollen little lipo cell no helpful idenfifying marks test voltage of dead battery and the induction coil to determine cell type needed, add referrer link to appropriate lipo cell on amazon
cut battery connectors one at a time with wire cutters to slightly different lengths
take new wire and add 2pin jst female connectors
then solder to + and – on the circuit board
quick test with 18650 cell as the voltages are the same..
