battery

Over the years i have i have found out different series size batteries certain brands are really good last a really long time in certain bikes and not on other sizes. I guess its the plate designs and how well they fit in the casings. I have had bikes with perfect charging systems and buy the best battery you can get and they last less then a year and go to walmart and get the cheapest one you can get for the same bike and it last twice as long. So what i am asking what kinds of batteries seem to last and work the best on these bikes. Lets hear battery name and how long they have been lasting. I need to buy one by the end of summer and what better way to get the one that works the best then ask people with the same bikes. Thanks
The bike also has a quick connect so when not ridden can put a few hrs charge every few weeks from my 1/2 amp tender. When you have 4 bikes you want things to last long as possible

 

I use lead-acid batteries.
The last 4 that I just bought (of 9 bikes) were: 1 Interstate, 1 K-Mart and 2 Wal-Mart batteries.
Afew of my bikes I've had for 5 years with the same batteries in them today.
I won't buy a battery that I cannot service.
There is always a little bit of acid left over in the tubs that come with the batteries. I use that to re-fill each battery if they puke from their first run on whichever bike it may be in. I don't always put an initial slow charge on a battery. Example; my KZ440 - I filled the new battery, let it sit for about a half hour while I tidied up the garage, put it in the bike and it started right up. Ran it for a week daily before I actually slow charged it.
My Goldwing - I use a 1 amp wall-wart transformer as a battery maintainer over the Winter. My cigarette lighter is wired directly to the battery and I use a cig lighter plug on the wall-wart. I just plug into the lighter socket on the bike when I maintain it. I'm 3 years with that battery, maintaining it with the wall-wart with no problems. I have a bunch of those wall-warts for all of my bikes (some are 500ma depending on battery size).
I have one of those little Die-Hard maintainer/chargers from Wal-Mart that gets used as well. It gets moved around for the most part; one bike to another. I use the clips with it primarily. The plug-in I have on my SECA, but rarely plug it in unless it's Winter. Rarely do I plug any of the bikes up unless it's Winter.
Been my experience that keeping proper fluid levels in the batteries with clean electrical connections is all that is needed as long as they are not over-charged and over-heated.
