I appreciate your assistance about attached pictures for Battery Cartridge RBC140 burnt jumper cable that burn cable connector? what is cause of issue? it started burnt and smell of smoke?
The battery age is four years.
It does look like that battery has corrosion from some leaked electrolyte. The expected lifecycle of the batteries are generally between 3 and 5 years. This does depend on factors such as environment (temperature etc) and usage how many discharges the battery has gone through. Often over temperature batteries (and older batteries near end of life) will swell and may start to vent and leak after a continued time of continued use in this status.
I can't say for sure but this would be the most common cause.
Thanks for your quick response. This is what I thought.
