I'm not sure what the intended budget is, but for about $30 you can add a
charge controller, which gives you a setup that works like a regular battery
charger. You can leave it connected all the time and it will maintain the
charge without overcharging.

Over-charged it. He got a free replacement battery, but is now more careful by
disconnecting the solar charger after a couple days use. I use a 5 watt solar
charger, got it from HF on sale for $30, and don't leave it connected more
than a day at a time.
