In the past year, I have put four Deltran Battery Tenders into service. They all seem to work just fine, so when my Vector battery charger died, which has been in service in the engine room of my boat for 4 years, I decided to try this Deltran marine charger. Several things attracted me to it. It had no internal fan to burn out (as did the Vector), it was made to be permanently left in a damp environment, unlike the Vector. And, the Deltran is designed to maintain a couple of batteries hooked up in parallel. Since my boat has two batteries configured that way as most small to medium cruisers have, it seemed like a viable solution.

I ordered the unit. While I was waiting for it to be delivered, I went to Deltran's website to read more specifics about the charger and discovered that it can only be used with an accessory mounting device at extra cost. I was not pleased, but my boat is in the water and not under cover. If it rains and my batteries discharge running the bilge pump, the boat could sink. So, I ordered the mounting bracket. Like the charger, the bracket seems well made, if not too large and heavy. The "bracket" is actually designed to handle three of these chargers and delivers the power to the chargers which plug in to it essentially the same way they would plug in to a wall socket or extension cord. Unfortunately, the chargers, according to Deltran, are NOT designed to be directly plugged in to an extension cord.

The mounting bracket comes with some stainless bolts which attach the charger to the bracket, then the whole, heavy mass is supposed to attach to the boat and an extension cord. Unfortunately, there is no room in my boat to attach the bracket, so I plan to simply lay the charger in the bilge when the boat is not under way.

When I tried to bolt the charger to the bracket, one of the pressed-in stainless "nuts" came loose and seized to the bolt. No amount of wrenching on the bolt head with vise grips on the round "nut" would free the parts. I wasn't keen on using a hacksaw to separate the two parts, but after an hour and a half, I gave in and cut the fastener, leaving a few scrape marks on the bracket. Naturally, I couldn't use the same mounting position, so I had to move the charger to one of the remaining two.

I set the assembled unit in the boat, but I am not pleased with the ultimate size and weight of the system. This system must be designed for much larger boats. Mine is a 28.5' cruiser with a 9.5' beam, but this is too big. A stand alone charger with a 110V pigtail and battery clamps would be a better solution.

This product is no good. This product seems like an afterthought and does nothing that it claims to do. This charger is not suitable for marine environments. I could not recommend this product.

These chargers maintain a dual battery system in our boat. Once the waterproof tenders are set up, just plug in an extension cord done. Fair price and fast shipping Amazon is good.
