I have a Do-all electric trap for clay pigeons. It runs off a deep cycle battery. I just repaired it and got a new 675 CCA marine battery, which was what the manufacturer recommended. Being it's a deep cycle, is it better to let the battery run down before recharging, or should I recharge it after every use? It's a typical Lead acid battery. I bought a special 1.5 amp trickle charger, with desulfinator, for this one, as the typical battery charger, did not seem to charge the previous battery.
