AssociatedEquipment ESS6007B 12V 40 Amp/130 Amp Boost Battery Charger (Intellamatic W/Override Switch)

Shipping took forever because it was on backorder however, this charger is exactly what I sought out! So far it is working great, you can set it to maintain a steady 13.6 or 14.2 volts which is great for reprogramming ECUs. Also has an override for stone dead batteries.

Purchased and returned both Chargers. One didn't work at all and the other worked intermittently for one day then stopped working altogether.
