marine/rv battery and trickle charger
Had my pop up truck camper in outdoor storage for just the past 5 weeks. Only electrical draw was CO/propane sensor. When I checked on the camper a few days ago my 1 yr old HD 24 -DP Interstate battery seemed quite dead. LEDs in camper wouldn't work.
I now have the battery at home with a trickle charger on it for about 72 hours. No indication that the battery is charged yet. Will it eventually charge or do I need to bring into a service station for a stronger charging?
Thanks.

Usually those sensors are two separate units and they are quite the power pigs. I was just working on a motor home today. I think the combined draw is almost a 1/2 of an amp.
You may need to charge your battery at a high rate to get it back to normal. Be sure not to boil it.

yes you need to hit the batt with 15 volts or so, The trickle may not be enough. You may need to burn off the sulfur.
Best to get a 3 stage or 4 stage charger...
Read here and hit all areas. Post back with any questions.

You would do well to check the voltage on the battery with a volt meter.
It is possible that your charger needs a certain voltage level on it before it will begin charging.
This is a safety feature to prevent shorting of the clips or if connecting to a shorted battery.
If the battery voltage went below 10.5 volts it could have been damaged to where it will have lost some capacity.
If the voltage went below around 8 volts it will be a total write-off!
