I would like to purchase one of these emergency battery jump boxes as I recently had a need for one and was stuck without it. I have a question for people that own them. How long do they stay charged for jumping once you have it fully charged. If I leave it in the garage or in the trunk of a car unplugged how long will they hold their charge. I am sure it varies by brand and size but some general info will help. Also what size would be recommended for the ST battery and starting system.
Thanks
