Welcome Bob,
Good info here and around the rest of the forum as well! I find google search will usually flag up what you are looking for on the site far better than the forum search engine which I find is next to useless!
Morgan's Mmm! Well they are really bitsers, Lot's of borrowed parts and with the 2006 plus examples they have more electronics and in the Morgan it doesn't have the go to sleep technology of it's donor vehicle so tends to drain the batteries, a good battery will get to the non start stage after about three weeks. Most of us just don't use them regularly enough to avoid this happening. When I first bought my 2010 plus 4 I was always suffering from this issue. I'd charge the battery up and then a couple of weeks later it was again to flat to turn the engine over! So I thought the battery was duff and changed it out for new. Same thing again although it did last a little longer being new and at the start of the summer season occurred less as I was driving more often!
I'd left the old battery on the garage floor and one morning my son's VW polo wouldn't start and the battery wouldn't charge so on the off chance I stuck the old MOG battery on, that was four years ago and it's still going strong with no problems whatsoever!
Upshot, I bough the ctek battery conditioner/charger, The 10 model without looking I think but it also reconditions the battery automatically and allows voltage drop and recharges to mimmick a more natural use. I had a lower spec model that I used on my lawn tractor but this one knocks it for six! The current battery has been on for 4 years now with no issues. As richard says there are no ideal solutions but a high spec Ctek conditioner seems the best solution for me as I take my car off the road in winter. Living in the wilds of Wales it's almost unsuitable for the Defender and ithe Morgan certainly wont like a sub surface role!
