Stop/Start Battery, Lack Of Availability
Last week was my 3rd customer within a couple months in need of a battery on their highlander. All of them had the stop/start. Toyota has a specific battery for this feature , bulletin T-TT-0523-19.
"The Stop & Start equipped battery is specially designed for deep discharges, and it is of a design called enhanced flooded battery (EFB). Characteristics of EFB type batteries are the ability to quickly discharge, and recharge."
This battery is getting hard to come by, and initially I was on a month long waiting list. Luckily at the last minute the dealer located one. Other dealers were bone dry as well. Aftermarket showed a back order.
Anyone use an AGM battery, or in the same situation? Hard to tell a customer your car will be down a month just for a battery
You can use a non-specified battery but you will get a message on the MID display that states “Non-Dedicated Battery”. The Stop-Start feature may also not function or may have limited function, based on the reading from the battery sensor that is on the battery cable. There is a “Change Battery Type” utility that can be toggled On or Off using Techstream Utility, not sure about this feature in…
Good info, thank you. I'll have to see if it's available on my am scan tool
My battery distributor said the AGM Battery is actually an upgrade from the EFB for most applications but not the Highlander
EFB batteries have been out for a few years now. Have you tried other sources?
