Yes you can but we need to know what the output(wattage) of the solar panel is to give you a useful answer. I'm suspecting you're using a 12volt, 7 or maybe 9 amp battery. If your solar panel is a 15 watt output, at the most ideal conditions, no clouds, full sun, panel angled perpendicular to the sun, you'll get about .8amp or 800mA. If your battery is discharged it will take at least 8 hours to recharge.
Another way to get extra life from your battery, keep it warm with one of those hand heater disposable packs, wrap it in a piece of cloth and put it under the battery. Don't let it get wet, that will kill the pack.
