My battery went dead over the winter. So I need to buy a new one. The manual says the battery should be 12 Volt 16Ah. On the internet I found 12v 30Ah Batteries at a reasonable price. Would the 30Ah battery be okay for my 1982 R65? Also, any battery recommendations? Thanks for any advice. (PS I saw via this site that Staabs has a battery for sale ( 12 v 30Ah) at $42.10 ( plus 18.66 shipping) and possible 5% discount. Does this seem to be a good fit and buy?
