After reading all the stories about Magnetek overcharging and people buying new batteries, I went with the Progressive Dynamics PD9255, with the remote Intellipower indicator. I now look at my water levels every 6 months and add maybe a cup of distilled water every year, between 3 batteries.
Very happy with the system.
