Bought my 2011 LR4 last year with 23K miles. Well, yesterday, as we were leaving the hospital in a torrential rain, my wife came back to tell me the Rover was dead. Sure enough a full no crank, no start. Called LR Road Service and got a jump and the alternator showed good charge. Went home, a 45 min. ride, let set and then later checked water level and put on tender. Next morning with full charge indicated, still dead. Checked on line for the nearest available battery and then had to go to 3 different parts stores before finding correct $230 battery. Installed and all is well again. Happy anniversary LR4. No other problems ever, now with 44K miles. Note: all new replacement batteries are only guaranteed 3 yrs.
