Bought in January, died in August. Worked for months to support two SLA deep cycle batteries, but when the batteries were used and needed charging, the unit would start charging for hours and then die. No light, no display, nothing. Wrote to ULTRAPOWER to let them know but received no response. I do not recommend purchasing this device, nor do I recommend this vendor due to the lack of customer support.
