My situation is this...
I have a Jeep JKU. We are going on a cross country (USA) trip this year. We are going to be off grid 90% of the time. I need to power a CPAP machine. On 12v it draws 2.5 amps for 30 watts. In the past we have hooked the cpap up to a deep cycle marine battery and could easily get about 12 hours out of the battery when fully charged. Again, in the past charging this battery up was no issue because we usually were camped in a campground and had access to 120v so I could charge up the battery.
Is there an effective way to charge a deep cycle battery using either the alternator, or does anyone know of a 12v noun battery charger I can use in conjunction with my 12v cigarette style plug in the back of the jeep? I wasn't able to find a charger for this.
Another option....I have run the cpap off the jeeps battery using the onboard 120v inverter. In fact we did this 3 nights in a row and just drove the jeep the next day to recharge. This seems like it may be an option but.... if in fact we do kill the battery out boondockin we're stuck.
What if I were to get a HD dual purpose battery like a Yellow top Optima,Odyssey or even a Duracell AGM and installed in my jeep....that would probably work too. Yet I still have concern about killing the battery.
One other thing...money is an issue here. I need to watch my budget. I'd love the get a dual battery system but they seem to be very expensive. If there is a budget minded option here let me know...
So....any suggestions?
