best battery

[dbmg]

I installed a Dekka 11/7/11. Topped it off before I installed it. Always had it on a tender. Every day when I parked in the garage, I connected the tender faithfully.
Well, sorry to say I need to replace it. Showed sever signs of stress early July now dead. Charger/tender says it's fully charged but no current to start the bike. I am very disappointed.

The biggest problem I have seen is the proper preparation of a new battery before installation in a vehicle for the longest life. I am sure that you have checked all the basics in regards to battery. Have battery properly bench charged, bench tested and then load test and see where you stand.
