Review: Excellent quality - Works fantastic to keep my lawnmower battery charged. It’s weather proof which I want for an outdoor storage space. This is my second one and it works great.
Review: Works great, I highly recommend for outdoor use! - I ordered this Battery Tender 800 waterproof charger a couple weeks ago and had installed it onto the battery of my mustang that sits for quite a while between starts and drives. Since the battery was at full charge it litterally took a very short time to go into storage mode and do what it was designed to do. Previous to this item I had the Battery Tender Jr that had failed after approx 6 months BUT, in Deltrons defense, I was using it between my jetski and my mustang. I knew it wasnt designed for outdoor use, especially here in the humidity of southwest Florida ( I did have the forementioned items under a carport and the item covered by the jetski seat or mustangs hood). I never blamed the Deltron company and never left a poor review as I was more to blame for using the wrong device for outside storing. I do also own the Battery Tender Plus and have used it inside my storage shed on my RV battery for about 1.5 years now with no problems at all. Though I have not given the BT800 enough time to write a thorough review I realize that thier prodects are above average for the price and wanted to share my overall experience in general with thier products. I can safely assume the BT800 will surpass its expectations as it was desinged as an outdoor product. My mustang does sit under a carport and the BT800 sits under a closed hood where it will never actually get rained on, come in direct sunlight, chemicals, or any type of water outside of humidity. So since its designed for this and even harsher conditions I feel assured it will give me years of practical use. I will come back periodically to update this review as time goes on. I would recommend any of the Deltron products to anyone who plans to use them in the way they were designed! ***update 2/1/15*** Unit still works perfectly under the stangs hood, keeps the battery charged perfectly so its ready to go when I decide to start or drive it. I still highly recommend this product for anyone needing to maintain a battery that is outdoors!

## Questions & Answers

**Q: How long roughly do you think it will take to re-charge dead battery? Been charging for almost 24 hours and light is still amber.**
A: A 'fairly' dead battery should charge up in about 24 - 36 hours. If the battery has access ports, you might want to check the water level (DISTILLED water only). If it is low in any of the chambers, then you would fill that chamber with distilled water up to the bottom of a concave meniscus level at the markers. ( http://en.wikipedia.org/wiki/Meniscus ) If there are NO access ports on the battery (sealed) and the light does not change to green after about 48 hours, you might think about getting a new battery. Make sure that the terminals are clean and that the connections to the charger and to the battery are solid.

**Q: How long will this reach? From recepticle to battery? Also does this come with the "quick connect" cable or just the alligator type clamps.**
A: The power cord to the charger is 6'3" long. The cord from the unit to its end is also 6'3" long. It ends in a quick connect/disconnect plug. The alligator clamp cord plugs into that connector. So the overall length from wall outlet to the battery is about 14'. If that's too short you can order quick connect plug extension cords. They make one extension cord that's 24 feet long. I use an extension cord that's about 2 feet long with a quick connect on one end and two rings on the other. The rings fit onto the bolts of the battery clamps. I leave it connected to the batttery and the other end is accessible through the grille, so that I can plug in the unit without having to open the hood.

**Q: When connecting to the car battery; Should the negative lead be connected to the negative or the engine block/frame of vehicle?**
A: The reason to connect (& disconnect) on a grounded member rather than at the battery is to avoid the risk of a spark igniting any combustible gases that may be surrounding the battery. Although the risk is low with a low amperage charger like this, it's a good practice to make the final connection to a ground remote from the battery. Just ensure it's a GOOD ground. My uncle had a battery blow up in his face (albeit under different conditions) and I can attest it's nothing you soon forget.

**Q: Does the quick disconnect stay attached to the battery while driving the vehicle?**
A: Yes, the pigtail comes with a rubber cover or the pigtail end that is not attached to the battery is a female connector.  Either connector is safe to keep attached to the battery.

### ⭐⭐⭐⭐⭐ Works with no hassles.
*by M***R on January 21, 2026*

Works extremely well with no issues. Read how to set type of battery. You need to do this whenever you hook device to new battery. Don't have to do this if it is installed or left on a battery.
