Greetings All,

It seems that there is some confusion/misconceptions about Sentry battery chargers...Actually all chargers, but with the recent years of newer technology in battery charging (switch mode or multi stage) when compared to the older (time proven) technology of Sentry & others being Ferro Resonant transformer type...below is a bunch of excerpts from a forum I visit...

All of this below is repeated info folks...Just wanted to try to centralize it...It's copies of posts & PM's I made & received...Hopefully it will answer some questions & dispel some BS... The names have been left out to protect the...

Please note: This all pertains to the long time produced, "C" & "G" series Sentry's, and still in production Sentry "FR" series, ferro resonant transformer models...The SM (Switch Mode 3 stage Smart Charger) models were imported, and had many failures & warranty issues, with NO replacement parts except for the main board (it was the only part except for the box it was in)  Cruisair/Sentry did not want to continue to offer a product with this kind of track record so they were discontinued...

Any questions on the original Ferro-Resonant model Sentry's...I'll try to answer, and they are completely field serviceable...

For the "SM" models the only answer is replacement...
