SLA smart chargers are cheap--plug and forget. That is why I like them--I just leave the batteries plugged in until I need them. Also, SLA hold their charge much better than other batteries; they can hold their charge for months with very little loss. Lead acid batteries are a fairly mature technology and are used in medical equipment, solar power, emergency lights, etc. Here are some links I have collected:
