I want to buy a car battery charger for my ice cream truck. Do you know how long the charge takes?

I bought an inverter for the chest freezer in my ice cream truck. The battery didn't stay charged more than 4 hours. I need to buy a car battery charger and another battery to keep it charged up. I was looking at a 2/6/10 amp charger. About how long would it take to charge one battery? I want a quick cheap one.|||an automotive cranking battery won't last 6 months in a deepcycle application - get the biggest heaviest deep cycle batteries you can afford.





you want to charge your batteries at a starting current that is no greater than 25% of the RC (reserve capacity) rating, or 10% of the AH (amp-hour) rating of the battery.





get a charger that automatically shifts into "float charge" or "maintain mode" when it's finished charging.





this is *not* the same as a "trickle charge".|||First get a deep cycler batties.. A fast change will take a hour.


A will good charge is a slow charge over night. It depend a lot on the charger. A Non Mechanic charger could take over night.


Let me run a idea by you. Install to battlery under the hood. Wire them in seares. You now have a heavy duty 12 volt system. I would put in a heavey duity altermate. You batties would stay charge. Run a set of cables back to your chest freezer. While are on you rute leve the engine running. At night hook the main battery up to the charger. This way you batties stay charged and you freezer stay cold. Unless you can hook it to and out side power.


The second idea is to install generator. Have it feel off the truck gas tank.


You can install cables to the vehicle battery. However you will only have 4 or 5 hours if the engine is not running.


Hope one of these idea will help you. But you will need to get deep cycle battery that used on a boat. It will give you a longer charge time.|||First - you should NOT use automotive battery if you plan to drain it till dead. You should use marine DEEP DISCHARGE battery. They are design to be drained till dead and then recharged.





If the battery was 70 AMP HOUR, then at 10 AMP, it would take at least 7 hours (plus about 10% more for inefficiency).








Good Luck...|||You have picked a very low amperage charger and you can expect it to take 8 to 10 hours with this charger. I would move up to a larger charger probably 2/10/50 and this way it might not take so long.
