Thank you for this great question, I would be happy to assist you. Regarding this Glas Votive Flameless Candle, the 2032 battery is positioned so the writing on the battery is visible when the battery cover is removed. In regards to the 4 pieces, if the pieces are more than the battery cover and battery having separated from the light, the unit is damaged and broken. Please contact us at 1-800-383-7323 and one of our representatives would be happy to help you get this replace.
Again, thank you for contacting us
