Heavy-Duty Waterproof Charger, a little slow but very effective
Deltran Battery Tender 12-Volt 800 milliamp Waterproof Battery ChargerThe Battery Tender Waterproof Tender operates in essentially 3 stages. It first initiates an absorption charge that attempts to charge your battery to 14.5 VDC at up to 0.8A (or 800mA). This bit of information was not readily advertised, so I was concerned when I heard my battery making gurgling noises while the LED was "amber" for the past 8 hours. This battery was only 2 years old with less than 5000 miles and had been maintained since day 1, so I was sure it wasn't a problem with the battery. It turns out that it was nothing to be concerned about since this charger was designed to be used for long-term storage of batteries.My previous charger, a Black & Decker / Vector 2A "smart" automatic maintainer tried to keep my battery voltage at 14.75 VDC at 2A for over 24 hours. Needless to say, I was concerned when I saw this happening with a brand new Battery Tender. I dug around on their website...

Nice Unit
I have been using battery tenders for a while now, but needed one that could be placed on outside vehicles without worrying about precipitation. This one was perfect. It's a simple little device - if you can plug a cord in and connect like colored clips - it's all you need.The construction seems even hardier than I anticipated - it seems very rugged. It has rained and snowed on it already with no issues. My biggest pet peeve is dead batteries, and battery tenders have worked great for me! My Harley battery is 5 years old and still functions like new.I highly recommend you pick one up if you have a battery that sits idle for more than a few days at a time.

Error in Amazon listing: 800 mAmp, not 800 amp
The Amazon title says this is an 800 Amp charger (which is a bit ludicrous -- most houses are only set to handle 60-150 amps). This device is actually an 800 milliamp charger, or 0.8 amps. This places it as comparable to the 0.75 amp Deltran Battery Tender Junior.The package includes high quality adapter cables, including both traditional claw-style clips (useful for charging/maintaining a stand alone battery) and o-rings to screw onto a battery for direct hookup while still installed in a vehicle. This latter option makes it supremely useful for maintaining a motorcycle over the winter, even outdoors.Deltran's "Battery Tender" brand series of trickle chargers are excellent quality. The Waterproof model maintains the high standard.
