Argodiode Battery Isolator 140-3AC - 3 Batteries - 140A

Argodiode Battery Isolators allow simultaneous charging of two or more batteries from one alternator, without connecting the batteries. Discharging the accessory battery for example will not result in also discharging the starter battery. Low voltage drop due to the use of high-efficiency Schottky diodes.

The Argo Battery Isolators feature a low voltage drop thanks to the use of Schottky diodes: at low current, the voltage drop is approximately 0,3 V, and at the rated output of approximately 0,45 V. All models are fitted with a compensation diode that can be used to slightly increase the output voltage of the alternator. This compensates for the voltage drop over the diodes in the isolator. 

Simply inserting the isolator in the cabling between the alternator and the batteries will slightly reduce charge voltage. The result can be that batteries are not charged to the full 100% and age prematurely. 

Alternator energize input

Some alternators need DC voltage on the B+ output to start charging. Obviously, DC will be present when the alternator is directly connected to a battery. Inserting a Diode or FET splitter will however prevent any return voltage/current from the batteries to the B+, and the alternator will not start. The new ‘AC’ diode isolators feature a special current limited energize input that will power the B+ when the engine run/stop switch is closed.

Busted spring on one side....
Color: Black, Size: 28-70"W x 48-120"H (Pack of 1), Color: Black, Size: 28-70"W x 48-120"H (Pack of 1)
I would have given it five stars except for the fact that 1) the instructions that come with it are miserable so you will definitely want to refer to the photos they have in the advertisement here, and 2) it appears that one of the vertical poles has a busted spring and I literally had to stuff some socks underneath it to make it hold. Definitely an eyesore, so I'm not thrilled about that. With that being said, I'm in an apartment and I don't want to drill in the walls to hang a curtain rod. My sliding glass doors have a track that I was able to get brackets that fit over the track to hold a pole, but I had one window that I could not do that with. I thought this would be an interesting way to hang curtains without doing damage. I considered those sticky tape curtain rod holders, but I was reading a lot of bad reviews about them not holding or them taking the paint off upon removal. I figured this was the better option and it gave the room some nice aesthetics because my furniture is farmhouse white wood with black iron accents, so this blended really well with the aesthetics of the room. I know that most people who did reviews used this product as its advertised to be a room divider for privacy... So I figured this is a nice way to review using this product in a different way. I just really can't stand window blinds, as they look so commercial and industrial to me... I needed a way to make the space seem more homey. While this is working fine for me, the reality is I have white lace curtains, which don't weigh much. I don't know that I could recommend this product, even though it says it can support a bit of weight, with curtains that are too heavy. Some of that, in part, is due to the fact that one of my springs is broken so it's not very stable as it is. However, even if I was not having the issue with the spring being busted on one side, I still don't think this would be good with heavy curtains (especially if you like opening your curtains frequently). It did come with curtain hooks if you have the kind of curtains that allow you to use hooks to hang them. I do not. My curtains just slide onto the pole. If they were the type that could be put up with hooks then opening and closing them would probably be easier and maybe not as big of a deal as it is for me with the type of curtains I have. I cannot comment on longevity as I just installed it today... If anything changes I will try to remember to come back and modify this review.

This was easy to put together. It is light weight. I use it in my spare room. And I have a light weight blanket I display, hanging over it.

Does not withstand any breeze.
Color: Grey
Not sturdy, tips over easily due to a small base and ultra light weight. Instructions were not much help but it’s pretty easy to figure out without them. Material is as expected.
