    it depends on the power of the equipment you want to install let me know the power and the power of your inverter then i can help you

    To answer we need to know 4 things:


    1. What model exactly is the whistler inverter? (so we can determine the efficiency)

    2. What is the amp-hour rating of the battery?

    3. What wattage rating is the inverter?

    4. What is the total wattage of the appliances you want to run?



    We have to know all four to estimate the current draw and the length of time for the battery to fall below the inverter shutdown point.



    And safety warning: remember - cigarette lighter plugs won't handle more the 130 watts of power, if you need more than a couple light bulbs lit you need to wire the inverter directly to the battery(s) (using a switch and fuse of course).

    if you going to use it while driving the car will keep the battery charged if you use it parked it will depend on how manhy watt is your tv or radio etc. usually small stuff use little so it may last few hours.

  • Norman Al-Anbar Sep 08, 2009

    you neeed to find out how many watt it use and how big is your battery I have forkleft battery old one I usually charge it every week and I use it for my house, tv, freezer, etc. Normal batteries usually last few hours if you have small sytem.

  • Norman Al-Anbar Sep 08, 2009

    yes you can use 2 of them to last about 18 hours...

    if one only without recheging it may last few hours...need to mnow how many amp your battery and how much use your system to be exact

Dometic brisk 2 AC can it be operated on a 24 volt inverter.


If your inverter puts out enough power, sure. It may drain your batteries pretty fast, though. Check the power rating of your AC and compare it to the power output of the inverter. Add a safe margin for everything else you want to run at the same time.

Dc lo keeps blinking on the fridge and lights go low in rv, power converter middle light is blinking green


The battery is not being charged OR is no longer accepting a charge.

The inverter does not charge the battery. An inverter consists of components that first convert the battery's low (12) volt "direct current" (DC) power used to power automotive devices to a higher (120) volt "alternating current" (AC) power that is required by nearly all household appliances to operate properly.

The charging of the battery occurs when either the RV's engine is running and spins the alternator, etc. OR when connected to another charging device - whether it is permanent or portable.

With the RV engine running, there should be about 13.5 - 15 volts, DC on the battery posts or terminals. This voltage is coming fromt he RV alternator and since it is greater than the 12 volt battery, "charges" the battery. If you use a portable charger - that is part of a generator, or plugs into a power port at a camp site, etc. this will charge the battery.

When none of these things is happening, the battery voltage will slowly drop. Once it is at ~10 volts, it is "dead" and will need to be recharged.

The battery will no longer accept a charge if a "cell" inside it has "opened" or "shorted", or if the battery is at the end of its useful life. The battery state can be checked quickly by any mechanic.

I hope this helps & good luck!

I have a Craftsman mulcher model 315.370270. The green recharge light goes on but the battery charge level stays in the red. Do I need a new battery and if so where do I buy it?


I guess you've solved this by now, sounds like you need new batteries if the mower lacks power after trying to recharge. There are two sealed lead acid 12-volt batteries connected together on this mower to provide the 24 volts of power. These are the same batteries that are commonly used on rechargeable power wheelchairs and scooters. So you could find them at a Durable Medical Equipment company. The last two times I bought them, I got them from a DME company where I used to work. I also looked into buying them over the internet. Just make sure the replacement batteries are the same size and specs. You could burn out your on-board charger by continuing to charge batteries that are shot. I did this a few years ago with my 315.370270. Since then I have been charging the batteries with my portable Craftsman charger. The 12-volt batteries last about 3-5 years. I have had my mulcher since 1995 and have replaced the batteries about four times. This is the best mower I've ever owned. I'm going to retire it this year, if you're interested in it for spare parts.

Does this camera operate on regular AA bateries. Put 2 brand new ones in and it will not power up. The manual says Kodak does not "support" Alkaline batteries....

chrissy66 (12/10/2007)reply to this comment (by James DeRuvo - 12/12/2007)Sounds to me like your lens may have come out of alignment. Was it dropped recently? Since your camera is still under warranty, the best thing you can do is have Kodak should fix it. If your camera is out of warranty, or if Kodak refuses to repair it for free, the one thing you can try is to try resetting the camera.

Kodak is also of the opinion that lens errors also occur when you use batteries not recommended by Kodak.

I recently chatted with a kodak specialist about this issue and he recommends changing your batteries to NiMh rechargeable batteries. These are the batteries that the camera is designed to use and using other types - like alkalines, can often cause the lens error to occur. If that doesn't work, then the camera indeed does need repair.

Rechargeable Ni-MH Batteries (AA Size): These Ni-MH AA batteries last up to twice as long as alkaline batteries when used in your Digital Camera - and you can recharge them up to 1000 times in our rapid charger.

I have a 1000 Watt Inverter, along with a regular car battery when the electricity goes out; Question: Can I use the 1000 Watt inverter and connect a 100 amp, deep cycle battery? I use regular house...


Yes, just be sure connections are heavy enough wire, and obviously the inverter uses 12 vdc input. Hook jumper wires positive to positive, negative to negative, on all 12 volt batteries. Deep cycle batteries will work better than car batteries. Just remember, when re-charging them, that they last longer when charged slowly, so don't use a high amp setting on charger and to monitor them closely, and do it in a well ventilated area, away from any ignition sources.

Roof top rv air conditioner installation


Waeco manufacture a rooftop A/C with a matching inverter.you will need to ensure that you have enough battery power when staionary but your al;ternator will provide power when mobile you could also use a small generator through a battery charger to keep your batteriesd charged up but this is not neccessary unless you are stopped for a long period of time.these units are fairly easy to install and come with fitting instructions for the A/C and wiring kits for the inverter..hope this helps

Power Supply How To


Because inverters operate from a DC (Direct Current) power source, usually a battery bank (one or more batteries), the battery source will have to be recharged at some point. (Remember that a battery discharged more than 50% is probably close to being dead.) Most cars and trucks recharge their batteries from an onboard alternator. Depending on the inverter load and runtime required, most power use applications will be covered by the charged battery, augmented by the operating alternator supplying a continuous charge to the battery. If the load is large (air conditioner, large draw power tools, large microwave, food freezer, ice cream machine, etc.), the user should verify that the installed vehicle alternator is of large enough capacity to operate the vehicle's power requirement as well as to fulfill the capacity of the inverter load. If it’s not, a motor throttle installation may be required to carry a small load, a larger alternator may be required, or a larger alternator, battery isolator and additional onboard battery bank may be required in order to meet the power requirement of the large load. Remember: it takes 12 DC Amps (at 12 VDC) to run 1 AC Amp (at 120 VAC single-phase) of power because there are voltage and efficiency factors to take into consideration.
