Well not good . Bought 2 batteries from a store in Anaheim thats a dealer for EPM. Since i didn't have an account with them they just did the sales as a cash sale invoice. Well two years later after moving my company to another state that invoice is nowhere to be found.. But the dealer remived the purchase date sticker so its july 2020.. well guess what, i was told these have a 36 month warranty when purchased and now oh its only 13 months... one battery out of 4 Deka i have is boiling out..all are in series for my rv so that makes no sense. Battery also only holds a 10v charge.others 12.84 so bad battery but since the store doesn't keep records are required by law on battery sales in calif, im getting screwed on the warranty as i told them look it up on penns page... then it was you dont have the receipt we cant warranty it. Btw, these are SUPPOSED TO ME 1131 MF maintenance free, they are NOT!!!!!! The one that boiled out was 3/4th of a gallon of distilled water low... wtf MF doesn't have screw in caps under the label... ive been dealer for yuasa for 30 years . Seal, MF means that read more
