Query: Fried My Battery!

Hugh disappointment. Instead of disconnecting my battery cables when going to Florida for the season, decided to use what I though was a reputable battery charge maintainer by Schumacher. Read all the instructions, followed to a fault and left. Came home three months later and the car started, no problem. All of a sudden a day later, it wouldn't start after a short trip, after a jump, came home and charged battery with my normal battery charger. Went out again the next day, same thing, wouldn't start. Took it into dealer, and they advised " fried battery ". They informed my it was the charger maintainer that fried the battery. (new battery by the way). Wrote to Schumacher and told them about their charger maintainer " float mode " didn't work. Never received a reply. Buy one if you want, but if your battery fries, don't be surprised. Wouldn't buy anything from Schumacher again.
