CTEK Battery Charger That Can Keep Truck Battery Topped Off if Key is in ACC Position

Published 02/04/2020

Question:

Will this work on my 2019 Ram 1500 if I intend to “plug in” the truck to shore power while I use the WiFi hotspot in the accessory ACC position on the ignition button? I need long term WiFi at job sites and don’t want to run the battery down or idle the engine for a couple of hours. Is there a better solution for this problem?

Yes, if you used the CTEK MULTI US 25000 12-Volt Universal Battery Charger # CTEK56674 attached to the battery of your 2019 Ram 1500 while the key was in the ACC position it would keep the battery topped off. The charger you referenced might not be able to keep up with the amperage requirements of your Wifi hotspot but this one definitely would since it can provide up to 25 amps as needed.
