Trojan is taking its role seriously to provide the right product. After exhausted study and search I bought two 6V (model in title) and have them in series. I don't know how well these would compare to a Rolls Surrette...but it seems to work for me without troubles. Shipped quickly and securely to my local dealer (golf cart place). But time will tell. Check the stats on their RE models.
