Have reputable garage check your battery and if it checks out OK, then have them give it a proper full charge. I found with my Battery Tender Jr. that it didn't fully charge my battery then maintain it, it would only charge the battery %80 or so then maintain it at this level. Not good.
A charger called a "Battery Minder" was suggested and so far I found it fully charges my YUASA and maintains that charge.
