Battery Life on 2012 26BH Jayfeather

Hey everyone I was just wondering how long my battery would last when not hooked up to any power source. Were going camping for a couple of days and was wondering the time frame of how long a battery might last with limited use. Thanks

Limited use is usually one battery one day... Using the furnace is going to be the big killer. Also using the automotive type interior lights is your next big battery draw. You need to install LED lights...

There are a few critical variables that determine how long a battery will last, which are primarily is what type and size battery you have and what is your power consumption habits. The furnace fan uses a lot of power. In the summer when we do not need heat we could go about two days with incandescent bulbs, not being too conservative. Since we have switched to interior LEDs, I cannot give you an answer as we have not run out of power yet on a trip.

If you are going out for a two night weekend you can do it, just be careful with your power consumption, and use it as a learning experience.

How often does everyone buy a new battery? Ours seemed like it didn't make the season. Of course, my hubby didn't re-charge it once a month as the dealership suggested.

My three 85AH standard issue Interstate deep cycles are over five years old now. This season will probably be the end as they are starting to drop in performance now...

Having smart mode charging technology on-board was our saving grace...

An automobile battery when installed in a vehicle with good charging system should last 4-7 years, depending on the original quality. That said, the same battery in a camper that is not regularly charged will last a considerably shorter time. Do not depend on the TV's charging system to keep it charged - it is usually only a trickle, and will not charge sufficiently to offset large use, like a furnace even for one cold night. If you do not let it get grossly discharged, and charge it regularly, it will last longer. And once a month is only a guideline for very limited use or storage - if you camp often, and use a lot of current, you may have to charge as often as daily or every other day. An exception might be the deep cycle marine batteries - they are more expensive, but are designed to withstand a lot of charge/discharge cycles. Hope this helps.

Kim, Are you sure it's dead? If you're not, take it to an auto parts store and they will test it for you. Some batteries can be brought back from seemingly bad shape with a powerful (equalization) charge. But maybe its time to replace it.

Treat the next one like tinlizzie23 suggests and they will last as long as Roy Ken's did. My Interstate SRM-24 is over two years old and I get the same amount of power over the same time period I got when it was new. The water has never been below top of the plates, and when it's not in the TT, it's on a shelf in the garage connected to a Black and Decker battery minder - about $20 at Home Depot. I was not battery savvy when I bought my TT, but there is a lot of good info on this forum and RV electrical sites. You'll be a pro soon. Good luck.

If I have my TT plugged in to a 30amp service this will charge the battery correct?

How long will it take a 1000w generator to charge my 2012 26BH Jayfeather battery?

The short answer is "yes". If you're plugged in to the CG electric your power converter will also supply power to all the 12 volt devices installed in the TT. (In other words they would work even if you didn't have a battery in the TT.)

When you're not plugged in is when the battery is used to power the DC devices. That's when you have to start figuring what your battery is capable of and how you want to use that power. ... long subject.
