This is a question that is constantly asked. Flooded batteries have a better temperature threshold than lithium. Lithium batteries cannot be charged if the temperature is less than 32 degrees. We sell Lithium, flooded, and AGM batteries. We do recommend Flooded batteries to most customers because of price, which is approximately 3x less expensive than Lithium. Also, the temperature range is a lot broader than Lithium. In addition, Flooded batteries are environment friendly, they are the highest rate of greater than 99%. Lithium are considered hazardous waste containing toxic or corrosive substances, therefore not good for recycling. There are still a lot of pro’s and con’s to both, but overall Flooded stands out the most. Call us if you have any additional questions.
