Using this LED memorial candle is super easy. First, open the battery compartment at the bottom of the candle and insert three AAA batteries. Once the batteries are in, turn on the switch, and the candle will start to give off a warm, flickering light. You can place it anywhere you like, such as on a bedside table or a memorial shelf. When it comes to maintenance, keep the candle clean by using a soft, dry cloth to wipe off any dust. Make sure to turn off the candle when not in use to save battery life. Replace the batteries when the light starts to dim. Also, avoid dropping the candle as it's made of plastic and could break. And that's all you need to know to enjoy this beautiful LED memorial candle.
