I have another rechhargeable battery question. Ive noticed that if i dont use my mp3 player for a while that the battery power is less when i use it after that period of time. Doesa lithium ion battery lose charge if its left unused or uncharged for say 3-7 days? thanks…just seeing if this is my bad luck with mp3 players or just the batteries behavior.
Generally, batteries do self-discharge over time, particularly rechargeable types. Also, many electronics draw a small amount of standby current to keep clocks running or to keep memory contents, even when the unit is “off”.
