Dear. List: Hello, list. I am not driving my D for a long time and beginning to worry about the battery in my D...so now I am looking for my new battery, red hat Optima, charger. I know that an Optima battery cannot use with any ordinary battery charger to recharge. It needs a special way to recharged. Then, I found a couple of products they say they can do it. one, I am thinking to get, is "Battery Tender Junior". http://www.batterytender.com/catalog/product_info.php?cPath=35&products_id=31 Battery Tender says, 'Fully automatic two-stage lead-acid battery charger. Perfect for all lead-acid, sealed maintenance free and gel cell batteries.' It is very light weight, tiny look and the most thing I like is that it is very cheap. We can buy from ebay around $25+$7.50 shipping. However, there are always some reasons why it is cheaper and I afraid of the reasons sometimes...so I look at other one, On Board Power Tender, in Battery Tender. Here come my questions, which one I should get. Or do I have the better way (product) to recharge my optima? Generally I don't mind spend money (but not too big) for my Delorean . Please anyone tell me any advice. I am very happy to hear. Thank you very much for help Blacknight [Non-text portions of this message have been removed]
