    Its better to buy one which is able to stop the charging if the battery is full because it will be always connected to the battery. If you buy one which is not able to do this the battery will be destroyed. Also, i suggest you to buy a bigger battery (about 2mAh) because the one you have will last for about an hour.

    What does your circuit do and what type of battery are you using?
