Description
The VoltageBoosterPRO Spark Edition is for the Toyota Tundra (2nd gen), Tacoma (2nd gen), LX570, Sequoia (2nd gen), Land Cruiser (7th gen)
VoltageBoosterPRO is a user adjustable diode modification with an inline fuse that allows you to safely increase your alternator voltage to optimize your AGM battery charging. AGM batteries (Optima, Odyssey, Northstar) are undercharged when used with some factory alternators. Traditional flooded acid batteries at charged at ~13.8v, but AGM batteries often specify a charging voltage of 14.5v+. Undercharging your AGM battery reduces battery lifespan and available charge capacity. The VoltageBoosterPRO lets you do a diode modification so that you can easily increase your alternator voltage output to charge your AGM battery at a higher voltage while also maintaining a fuse (unlike the commonly done GM diode mod).
We HIGHLY recommend not doing the DIY GM diode mod, which when done REMOVES the safety fuse of that circuit. The drop in GM Diode is NOT a fuse. Shorting a fuse using a plain diode is a bad idea. A team of engineers spent years designing the electrical system of your truck. If you do any diode mod, please make sure you have a fuse in that circuit! Otherwise if you have a short circuit, you will have a full battery amperage fire in your engine bay!
With this mod, you retain the fuse on that circuit, in a clean, easily installable and easily removable package.
The “Low” mode provides ~0.4-0.5V of increased alternator voltage. The “High” mode is ~0.8-1.0V.
Each unit is made in San Antonio, Texas.

I was hoping for .5 on the low setting and got .6! Incredibly easy to install also!
No complaints, device seems to be doing what it is supposed to do. I would recommend it to a friend if asked.
I bought this in Lou of the single diode mod because I felt it was much safer for my battery in for my overall truck. I noted that the voltages both high and low are on point with the charging voltage is for my particular battery it’s sweltering hot in Texas so I monitor my battery regularly. I am very pleased with this product.
Replaced an “EBay diode” solution with this product. Very stable and consistent performance. Would recommend to get longer life and better reliability from your battery.
raised my voltage to 14v on 2014 2nd gen Tacoma
