2018 Caravan still has original Johnston Control battery and it was dead today. Charged for 30 minutes and came back to life. I had already ordered a battery from Walmart cause I am tight on money. Walmart Maxx battery was 50 cheaper than Autozone and 100 cheaper than Goodyear. 3 year warranty and 5 year prorated. Hopefully it will last. 12-17 to 6-24. Can't ask for more. 2 months before payoff and 1/2 a payment.
