I'm sure you know this but check your water level. If low, fill it to about 1/2" of the top with distilled water. If you've ever put tap water (even a little) in your batteries, that will destroy them ina short period of time.

I've used these batteries/solar panels for two summers and they fit my usual needs perfectly. By 11:00AM my batteries are reading right around 13.4 V. So this system has worked for me in the past.
