🔌 BatteryMINDer 210-AY SmarTECHnology Multiple Battery Charger Connector for Enhanced Charger Performance Review

I use this product to service two 12 volt batteries at the same time. One battery is on the alternator and the other in my car and both are rarely used. The product works as intended and as described.

I use this adapter to charge 2 batteries in my cargo trailer. I have a 100W solar panel and a charge controller. I plug it in and it keeps my 2 batteries fully charged and ready to go while in storage.

Tested with BatteryMINDer 128CEC1: 12 volt 2/4/8 amp battery in Jeep dual battery system. The polarity was correct for both batteries. Two fuses are blown. Replaced the fuses, I'm afraid to try again. The Odyssey charger and batteries are too expensive for further experiments. I'm sorry I bought

I bought two of these Y-connectors. I have a 12 volt BatteryMinder to keep two car batteries running at full speed this winter. Another Y connector that I use with a 24 volt aircraft battery to keep two aircraft batteries charged and serviced. These devices are well built and work well for me.

I'm a battery lover. I've been using them for many years with great success. I recently bought a larger battery charger/maintainer and wanted two batteries connected to it at the same time. For a while I tried to connect the connection cables in parallel, but found that I had to reconnect everything again and again in order to use the required battery. I chose to do this because the fuses in each circuit provide independent protection and now I can just pull the SAE connector out of the battery

Used to charge two jet skis. A fuse was blown and I kept checking the charger and it said everything was fine. I ended up spending the money on this splitter and $120 on a new battery to replace the one year old battery. I will no longer use splitters. Spend the extra $20 and just buy a second charger. If there is a problem, the charger will let you know that something is wrong.

Very easy to set up. We service three deep cycle batteries and one lawnmower battery. The device regularly checks the state of charge of each battery, charges when necessary and constantly desulfates all of them. You can see what's going on at a glance. With the beginning of spring, our batteries are fully charged and ready to go. Recommended by our van mechanic for use in our long cold winters.

Unfortunately I have to update my previous 5 star review. This connector drained one of my year-old airplane batteries, but BatteryMINDer itself never gave me any indication that anything was wrong. I was able to salvage the battery, so it didn't cost me a new battery yet, but probably reduced its lifespan. If you are looking for this to stop aviation, just buy a charger for each battery. i'm doing it right now

I recently purchased this product and have only had it a few days. It seems to be doing exactly what it was designed to do. I am currently using it with two deep cycle RV batteries and all seems to be working fine. I can buy a second unit to use with a third RV battery. I assume this will extend the life of my batteries, but I've only been using it for a few days. That's why I only give four stars in this category. In fact, it can be proven to deserve a five-star rating.
