Title: Goes dead if you let it set
Review: I bought an Orion Dynamo Pro 17 two years ago. I used it 3 or 4 times and then put it in the garage for a year. After that, it would not accept a charge. It was completely dead. I checked into replacing the battery for $50, but it requires completely disassembling the unit. I think the lead-acid battery technology is terrible and this unit is not made for battery replacement.
