The Battery Tender Waterproof 800 12-volt/.80-amp Battery Charger is the ultraportable solution to the challenge of keeping vehicle batteries optimally powered when not in use, and in situations where water may be present. It is able to charge any lead-acid battery, including standard and sealed AGM and GEL Cell battery types, and is also designed to be easy to use in small spaces, to utilize a 3-step charging program and safely function in a fully automatic mode. Taken together this makes the Waterproof 800 an excellent means of ensuring that the batteries for your ATV's, watercraft, motorcycles and boats are fully and safely charged and ready to go when you are.

Safe, 3-step Battery Charging
The engineers at Deltran led the way in innovation and convenience by introducing the International Battery Tender Waterproof 800. Since its introduction in 2003, it has been widely accepted as a solid new addition to the Battery Tender family of charger products. This compact 800 mA battery charger has all the charge characteristics of its cousin the Battery Tender Junior. It incorporates highly efficient surface mount technology electronic components. The interior is completely encapsulated, protected from shock, vibration, and moisture by an electrically insulating, thermally conductive, flame retardant, UL recognized, synthetic epoxy resin compound. It's tough, affordable, and a strong, innovative battery charging solution. This charger is no larger than a standard computer mouse yet packs 800 millamps of pure constant current charging power. Coupled with a "brain" (IC chip) and a 3-step charging system that constantly cycles through monitoring, charging, and then maintaining your battery--even while totally submersed under water--it's perfect for all outdoor types of ATV's, watercraft, motorcycles, boats, or anywhere water is a threat.

Key Features:

  • 100% waterproof.
  • Complete 3-step charging program (initialization, bulk charge, and float mode).
  • Automatically switches to float / maintenance voltage after fully charging the battery.
  • 12v-800mA "Super Smart" technology.
  • Spark proof and reverse polarity protected.
  • Designed for use on all AGM sealed maintenance free, lead calcium, and flooded batteries.
  • Three year warranty.

*Note: All Deltran battery chargers will charge all types of lead acid batteries: either flooded (standard STD), sealed maintenance free Absorbed Glass Mat (AGM), or sealed maintenance free gelled electrolyte (GEL) batteries. However, for optimum battery performance in deep cycle applications (for example, running a trolling motor), it is best to chose the Deltran charger that has the charging software specifically designed for the battery type. Fortunately, since the technical staff at Deltran has developed charging software that works equally well for both STD & AGM batteries, the only choice to be made is between 2 models: either STD & AGM or GEL software.

Three-year Limited Warranty

Warranty is void in cases of product misuse, disassembly or modification.

Deltran Battery Tender 12-Volt 800 milliamp Waterproof Battery Charger

The 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 and discovered a PDF that indicated the Tender would try to reach 14.5 VDC for the absorption phase, at which point it would switch to a trickling charge and finally the maintenance charge. I logged all of the readings and confirmed that once the battery reached 14.4-14.5 VDC, it would start to trickle down finally remaining at about 13.12-13.22 VDC @ 20-100 mA. A modern car's parasitic draw is about 10-50 mA, so the maintenance charge is to compensate for the parasitic draw and for self-discharging of the battery. I discovered the Tender does a much better job at a maintenance charge because I have yet to see the Tender go into the Amber-LED mode, whereas my Vector/B&D occasionally switches back and forth even on a fully charged battery.

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.

I have three of these. In the northern Ohio winters where temps can sometime go down to single degrees at night, I know the truck will start in the morning. I keep one on the generator and tractor for battery maintenance during storage. They work perfectly.

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.

I really like it. It looks really well made. And it works very well. It charged my bike quickly when I accidentally drained the battery because I left the lights on. I bought the 25 ft extension with it also. The only thing that you have to be aware when using this charger/tender is that the battery must NOT be completely drained out. If the battery reads less than 3 Volts( I think), it will NOT charge it. There is only one light on the charger. It will light orange when it is charging and it will turn green when the battery is fully charged (or it won't light at all if the battery is completely dead). If you own a motorcycle the supplied hook up will allow you to charge the battery without having to remove it from bike. The only downside it that this model is on the more expensive side. Having said that, being water proof and having a built-in fail safe switch (won't hurt the charger or battery if you hook it up wrong) is worth it, I think.

I have 2 of these now, and they work great. I have them hooked up outside, and I dont have to worry about bringing them in. Light indicators on the chargers seem to be accurate. I have never had any problems with this product. Plus the kit come with clip or permanent attachment setup. Nice product!!

Used this to keep jet ski battery charged. After 15 months into a 10 year warranty it has failed. Deltran charges $9.95 plus postage for repair or replacement.

This charger gets used in my barn. The waterproof nature is a must for the damp and dusty conditions there. A big plus is the fact that I can leave it on 24/7, ensuring that the equipment has a full charge and a battery that lives a long time. The low power is perfect for this kind of duty - it won't run up my electric bill. It's 800 mA, not 800 A; it's a smart trickle charger, not a welder. A big plus is the smart circuitry that prevents overcharging. I won't buy a dumb charger ever again.

I also got the cigarette lighter adapter so that I can use it in the other car, which doesn't always get regular use.
