As previously advised on here , was away for April/ May this year in Aus. After reading the advice on here, I made sure the 12v battery was fully charged via my CTek . I did not know about double click, so only single, but on return, car started normally and has continued normally since. The key to it all is fully charge if you are going to be away. Personally I cannot talk highly enough about CTek , I have an S Class Merc, and because I only use it for long journeys, and also because I love driving my wife’s Jazz, the CTek is pretty permanently on that, as there is a strong battery drain due to the electronics and security protection, plus it has 2 batteries.
Having said all of that , with 8 Hondas over the years, never had a battery problem through lack of use.
