PM coins like the opal series have a built in light and button Li battery. I know Li batteries have a long shelf life but is there a risk of leakage, corrosion or other incidence when stored for years that may damage the coin or box. Is it best to take the batteries out for storage ? Any thought on this ?
this is a good point. I would take it out,just for precaution.Thanks for this.I will take mine out tomorrow
Yes take them out, risks of leakage. Keep away from flammable stuffs or even high temperature might have a risk of explosion. Just write on a piece of paper the size of the battery just my 2 cents
