210-AY SmarTECHnology Multiple Battery Charger Connector – to Be Used with BatteryMinder Chargers

A little Pricey but works nice.

Very easy to set up. We are minding three deep cycle batteries and one lawnmower battery. The unit periodically checks the charge on each battery, charges when necessary, and constantly desulfinates all. You can see what's going on at a glance. When spring arrives, our batteries will be fully charged and ready to go. Recommended by our RV repairman for use during our long, cold winters.

Works well. I have used it for quite awhile and it performs as designed. It seems to well built and have A well thought-out design. The manual has most of what you need to know, but there is information lacking.

I use this adapter for charging 2 batteries in my cargo trailer. I have a 100 watt solar panel, and a charging controller. I plug this in and it keeps my 2 batteries fully charged and ready to use while being stored.

I recently purchased this item and have been using it only for a few days. It seems to be doing exactly what it was designed to do. Currently, I am using it on two deep cycle RV batteries and all seems to be going well. I may buy a second unit so I can use it on a third RV battery. I assume it will prolong the life of my batteries but I have only been using it for a few days. Consequently, I only gave it four stars in that category. In fact, it may be proven that it deserves a five star rating.

I'm a battery minder believer. I have used them for years with great success. I recently bought a larger battery minder charger/maintainer and wanted something to connect two batteries to it simultaneously. I tried jumper cables in parallel for a while but found I was always having to reconnect everything to use the battery I needed. I chose this because of the fuses in each circuit for independent protection, and I can now simply pull the SAE connector from the battery I need and move on, and easily reconnect when I'm done. I was going to make my own cables, but by the time I bought the cables, inline fuses and everything I needed, I decided this was a more sensible solution, although a little more expensive. If I could make a change, I would like the two output leads to be at least 3 feet long, each. My batteries are mounted in equipment, so I had to extend one lead to reach between the two batteries I wanted to maintain. Other than that, this is a quality product. Make sure both batteries are charged independently to near full charge first if needed, per the instructions, and dual battery maintenance is easy.

I purchased two of these Y-connectors. I have a BatteryMinder 12 volt to keep two car batteries at ther peak voltage this winter. The other Y-connector I use with a 24 volt Battery minder for aircraft to keep two aircraft batteries charged and maintained. These units are well built and are working well for me.

The batteryminder stuff has done a great job of keeping my batteries charged and maintained. I was skeptical about the claims it could desulfate and "renew" dying batteries but it certainly seems to have done the job. Purchased several quick disconnect attachments and a few extensions to be able to hook up both cars and the bike.

Well made, works great, easy to use.

up to 8 batteries at once with these add ons they work well

good product

Works perfectly with BatteryMinder 128CEC1: 12V 2/4/8 AMP Battery Charger-Maintainer-Desulfator
