Our GS-350 does some really wonky stuff when the battery is weak. Back during lockdown the car went into carnival mode when i tried to start it after it had sat unused for a couple of weeks. Was kind of scary as I've never had a car do that before. As the original was ~7 years old at the time I changed it on spec with an AGM unit and all was fine afterward. In hindsight the OEM Panasonic battery just needed to be recharged and it's still fine today. I keep it around to use with my electric winch. The car goes on trickle charge if it sits unused for long periods. Same for the Frontier.
