I have a group 24 deep cycle battery. Im in no position unfortunately to change it at this time. I have a full week long trip planned and will only have battery power for that entire time. I plan to switch over to LED lights now but in you experience if I was to really conserve my power using lights only when really needed and say operate the water pump once a day for a short time for dishes and maybe 1 quick navy shower, can I make a full week without going beyond half charge? I won't be able to charge the battery until I get back on the road to go home unfortunately. My phone will be charged in the car or by a separate battery pack. I will use my head lantern more for light. So mainly concerned about the water pump. I won't use anything else on 12v. If it was just my lights I know I could easily make it, but I have no clue how to judge the water pump. i will be monitoring the battery daily with my multimeter and will adjust as needed but trying to get a base line to go on. Thanks all and happy camping.
