I seem to go through battery's like hotcakes. My battery now is in question yet again. Last season almost exacly a year ago (6/10/10) I was in a pinch for a battery & bought one at walmart. I brought it home filled it & then put the battery on my Deltran battery tender to a full charge. The next morning I installed it into the Wee. I did all the right things. December came I put the bike away with a tender. This battery has never been fully discharged. Is their a difference in battery quality? I know walmart does not make that battery.

The AGM batteries at Wally World are fine -- I have one in another bike that's been going strong for four years.

Make sure your charging system is healthy, and that you aren't placing too much load on it with driving lights or heated gear. A lot of stop-and-go riding can also cause problems, since the charging system does not keep up with the load at idle. You might attach a meter and go for a ride to get an idea how well it's keeping up.

Believe it or not, V-Stroms have pretty much the same charging system that has been in use since the '70s. The Stator Papers over at thegsresources.com (a vintage Suzuki web site) are a very thorough overview of charging system theory, testing, and repair.
The GSResources - Stator Papers I - A primer on GS charging systems

Unfortunately, the root cause of charging system failures has been the same on every Suzuki for over forty years -- the crappy wiring connectors are usually unsealed and many are undersized, leading to corrosion, overheating and failure. Cleaning all wiring connections, paying special attention to the charging system, will often get things back to factory spec. That's why you can't just plug in new components (like batteries, stators, regulators) and ride on -- you first have to address the root causes of the problem.

When I got my Vee, I spent a couple of hours cleaning all the electrical connectors, and sure enough I found several connections with corrosion and the headlight connectors showed evidence of overheating.

I concur. There is something going on if you are going through batteries and keeping them on the tender when not used. I would definitely look into issues on your bike, but your tender could be the culprit as well. If it is malfunctioning it could be doing some funky stuff to your battery.

I have a wally world battery and tender and have no issues after 3 years. *knock* *knock*

A battery I bought at an auto parts store out west failed after 6 months during an eastern tour. A parts guy in a cycle shop where I replaced it told me a story about the time he worked in a Korean motorcycle shop and they found it was cheaper in the long run to replace the Chinese batteries the bikes came with up front than to continually deal with the failures. Of course my battery had 'made in China' on it. I replaced it with a Yuasa which cost double what my Chinese battery had.

Ok, lets see what happens now. Removed fairing & cluster cleaned all connections & used Di Ele grease on each connection when I put them back together.

Something's definitely not right. I replaced the the battery that came with my '02 a few months ago. Probably should have been changed last year, but still, that's over 8 years. Maintenance was limited to throwing the 1 amp trickle charger on it once or twice through the winter during the longer spans when I couldn't ride. It was even drained almost flat once or twice by a pair of heated grips before I changed the wiring to the switched power source.

I would have to agree with a check of the elec system. I got 8yrs out of the stock batt in a ZRX and bought a Tru-Gel and have been very happy. Also replaced the batt in the 06 V-Strom last yr with Tru-Gel also. During the winter I switch the batt tender between bikes every couple of weeks.
