finally had to replace my old "six pac" battery it was a factory second and was in the pickup a good seven years i would guess. the old one and the new one are based on the optima style battery. i just love the clean battery box and cable ends. and the red thing is one of those battery operated trouble cord with the neon lites. i love this thing five hours of operationg before recharging and no cord to run over with the creeper. by the way the old battery is going into my old gas powered sprayer.
