"Purchased a D27 Yellow Top Battery for a 2010 Tacoma. Warranty was 3 years, but supposed to last much longer than a 36 month standard battery. At 3 years and 2 weeks, the battery quit, would not charge, would not deep-recharge using an AGM charger per MFG instructions, and no options from Optima. At $300 with tax, this battery is not worth the money and does not stand up to the claims."
