the special battery recharger for those special batteries that will
recharge the batteries in about fifteen minutes.Check your local area
Wal Mart stores and similar stores for them.Ray O Vac batteries are the
best batteries in the World,,, because I say so.You can use an Inverter

using Ray O Vac batteries since the 1940's when I was a cute little boy
with nary ever any problems.Those Cat Of Nine Lives batteries were
pretty damn good batteries too.
