Anyone tried this? Voltage booster AGM

[derek_flint]

Good day all. I am having to replace both Northstar AGM batteries in my 2015 trail edition. Yes I have seen the posts on voltage boosters and was wondering if anyone has tried this? H113-L-2 Voltage boost harness for Toyota 4 pin regulators for a 1 volt increase for AGM batteries - Mechman Alternators

I used to rebuild starters, alternators and generators for many years. If you wanted higher charging voltage, we installed a Transpo higher voltage (14.7+v) regulator or an adjustable voltage regulator depending in the alternator.

I can wrap my head around how that harness ups the voltage after the regulator.

There are a few possible options.

Custom alternator built for higher voltage. Get a good known brand, like Optima, battery tender that has the AGM charge option and charge the battery a few times a month.

With the 3rd Gen Tacoma you can get a tuner to up the charge voltage through the ECU since that is what controls the alternator charge. I don’t know if that is the same for the 5th Gen 4R.

I got the Arclightleds that has 3 settings which was helpful. Has been working great the passed few years with a separate battery tender i use now and then since i don't drive a lot.


Triple State Voltage Booster - 5th Gen 4Runner — ArcLightLEDs

Not really sure how that cable will do much of anything.

At least that Arclightleds has a fuse!

Did you end up getting this? I'm leaning this way but cant find a single installed review of it. Or did you go another route?

I’ve been running mine for 2 years and so far, it’s been good!

About 1.5 years for me so far, through two Vegas summers and what passes for a winter around here...

In my 02 Tacoma... no issues.
The AGM battery was much happier with that super easy mod.

$60 for a fancy cable with a resistor? There's a $4 solution if you want to try that first.
