Argodiode Battery Isolator 180-3AC - 3 Batteries - 180A

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.

Should have got this ages ago!
Color: Gold, Material Type: Stainless Steel
Heavy enough to stay in place, but light enough to pick up and carry to the cleanup site. Very simple, but elegantly fashioned.

Heavy Duty Paper Towel Holder
Color: Brushed Nickel, Material Type: Stainless Steel, Color: Brushed Nickel, Material Type: Stainless Steel
Nice looking, heavy duty paper towel holder. Looks like it'll be durable. The top did have a couple of dark, tarnished looking spots but it's not too noticeable.
