Diehard Battery maintainer, a must have for stored vehicles September 10, 2010
a must have for all of us who store vehicles for long periods of time and would like to save our batteries.
this unit maintains the batteries at proper charge levels without ruining your battery and you don't need but to checks it's operation once in a while.
only problem is if you don't catch in time that the unit has failed and allow it to sit a while, it will kill you battery.. (but that is why you buy diehard batteries, as they have great warranty).

Keep an eye on the status lights!!! April 25, 2011
I've had one of these devices for a year and it's been working fine. Recently I noticed a problem with my unit, which I will put in bold so others can easily find it (because it seems to be a fairly common problem)...
THE YELLOW AND GREEN LIGHTS ARE BOTH ON AT THE SAME TIME.
This indicates that the battery is completely charged (green light) but also that the charger is still in charging mode (yellow light). If this is the case, the battery will be damaged by over-charging.
Thankfully this item is covered by a 3 YEAR WARRANTY. I still had my original box and receipt, so I exchanged it for a new one and it's working normally.
So my advice to you is to monitor the lights on the front of the device and keep your receipt...just in case!

Convienient battery maintainer December 29, 2011
By harrisdm
of Hollywood, MD
Pros:
Price,Good value,SizeCons:
None,noneI have four different battery maintainers. I bought this unit because it was the only one that included a cigarette lighter connection plug. It allows me to quickly hookup and disconnect to an interior connection and not have to raise the hood. As for performance it works about the same as the other units I routinely use on my boat and tractor. The unknown is how long it lasts. I have used it continuously for about three weeks to maintain the battery in my 2009 chevy 1 ton truck. It frequently sits for two to three weeeks with no use. The doors or opened frequently during the non-use period which along with the vehicle computer consumes battery power without recharging.
