I have only had my cordless trimmer/clipper for two months and it won't work anymore, or it only works for a few minutes before it stops, is there a problem with my unit?

On any cordless rechargeable product, you must use the unit frequently to keep it operating properly. As stated in the instruction booklet, you should run the trimmer's/clipper's battery completely dead at least once a month, otherwise, if you only use the unit two minutes every day eventually it will work for only two minutes between charges. Thus, to prolong the life of your unit, you should completely discharge the battery at least once a month.
