I currently have a battery charger for a 12 volt battery set at 10 amps and it is connected to a deep cycle battery. The battery is then connected to a 400 watt inverter to run my laptop. the problem is I can not disconnect the charger from the battery very easily so I would like to put in a diode in series with the charger to prevent discharge of the battery through the charger when the charger is off. I am not sure which diode I might need all I know is that the charger has a output of 12 to 15 volts DC at 10 amps max to charge the battery. I know the battery is discharging through the charger because after leaving the charger off for some time usually 12 to 15 hours the charger will charger the battery for at least 1 hour when it was fully charged when the charger was turned off.
can you please suggest a diode for this application or at least tell me what I need to look for in the store when i go to purchase one.
thank you
