Can I use this unit long term with batteries only, provided I keep them fresh?

I used this with one set of batteries for about 4 months. Finally had an electrician add an outlet in my water heater closet, so now the batteries are just in case the power goes out.

Yes you can power the system by battery. Just be sure to use fresh batteries when installing them. The unit will have a visual and audible warning when the batteries are getting low to warn you to replace them.

Yes you can, just monitor them. It is suppose to beep when batteries are low.

I would not recommend it. The batteries are backup if there is elect service interruption.

Yes, Thats how I always used it. This battery will die after a couple of years. Might that be your problem?

yes the battery in our unit is still going after a year. it should last longer than that.

What is the shelf life of this battery unit if I plan to keep it as a back up battery?

You will need fresh batteries ... I was real happy with mine for awhile, then it quit working, either a short somewhere, or blown speaker.. I never had it up loud enough to blow a speaker but that is what it sounds like ..

I'm sure you can use rechargeable batteries as long as they are correct size. I use mine for a while and due to climate and salt water air exposure, I remove the batteries when it's not in use. battery bleeding acid will corrode the connections. You don't want to leave batteries unattended in any unit for too long.

This is a great battery maintainer for long term. Remember though the batteries must have a charge in them before this will maintain them. It will not charge a dead battery. Since I have purchased mine this past summer, I have never had to place the battery charger on the cart. This will keep the batteries charged and maintained as long as the batteries are not dead or you have a bad battery in the series. If we use the cart all day and charge gets low it may take more than a day to get full charge back but this unit is better for the batteries as it is a slow charge and maintains the life of your batteries so if you do not need to use the fast charger to charge, your batteries will last a lot longer.

It can be depending on how you use it. Personally, when I'm done using it I remove the batteries and put the device and the batteries in a little sack. But if you tend to use a setting where you want to keep the values you set, then you'll want to keep the batteries in and make sure you have extra batteries with you in case they die (each time you replace the batteries, you'll have to reset the values).

I think the batteries would last a while with that type of use. I also think you will be please with the purchase. I used mine to build some shelves from raw wood. I went through 1 set of batteries until my husband pre-drilled the rest of the wholes for me.

I don't think so. The units are all plugged into the wall. I have never had to change any battery and I have had it for 1 year or more.

I don't think it would be an issue if they provided the same power as a disposable. I've only used disposable, however, mainly because the batteries last a very long time. Power usage is really minimal and my batteries are still functioning at the end of my growing season. I've replaced them each year just because I don't want to have them run out when I am not around. I water between May and October, so that may be the reason they last so long, as well.

You can but it ruins the battery. The battery will become dependent on the constant charge and will weaken.

Ideally, the batteries should be changed once every six months. But, keeping the batteries fresh will ensure a fresh fridge. It has completely eliminated odor for us!

I've left them in for a reasonable period of time (life of batteries) with no ill effect, though it could possible shorten the battery life. I have no evidence, just a hunch.

Yes, as long as you use them once a month or more. Mine are working fine and that is what I do. When they are not in use during off seasons, you must unplug them from the charger and store them.
