My DieHard inverter beeps every time I start my car

My Diehard inverter is wired directly to my car's battery and I use it to power a tablet computer. It starts beeping every time I start my car and I have to turn it off and back on to reset it. The owner's manual said this would allow it to maintain continuous power. Why is it still beeping? Thanks

SOURCE: All started when the chain got loose, I tried to

10 beeps signal a blockage. This is what happens: the control board monitors the current absorbed by the motor; when a mechanical fault or something else is blocking the movement the motor automatically tries to overcome it by delivering more power, in the process absorbing more current; this current triggers the warning and the door system goes in danger mode - it returns the entire unit to the original state (fully closed or fully open). This happens like that so if someone gets caught it won't gets squished.
In your case the damage is internal, in the gearing between the motor and the chain sprocket - it occurred when you have tried to install the chain. You will have to completely dismantle the motor and its gearing to see what broke in it and fix it if possible. Worst case scenario: you will need a new unit.

This is battery related. On top of your unit is a battery pack with three colored led lights. You can tell what is going on by looking at these. This information is in your manual or here it is.
GREEN LED: All systems are normal. A solid LED light indicates the batteries are fully charged. A flashing LED indicates the batteries are being charged. NOTE: Batteries do not have to be fully charged to operate the motor unit. YELLOW LED: The motor unit has lost power and is operating off of the BBU. A solid LED with beep, sounding approximately every 2 seconds, indicates the motor unit is activating the door and is operating off of the BBU. A flashing LED with beep, sounding every 30 seconds, indicates batteries are low. Once the power is restored the BBU will recharge. This is indicated by a flashing GREEN LED. RED LED: An error has been detected and the BBU will automatically shut off. The BBU will attempt to restart by reconnecting to the batteries. If the error is still present it will shut itself off again. This process will repeat every 5 minutes or until the error has been resolved. This is used to prevent further draining of the batteries. If a red LED remains on when the power is restored, and is accompanied by a beep sounding every 30 seconds, please call for service.

Do I have a negative battery system or positive battery system?

If you have a 12volt standard electrical system in your vehicle.
It is both positive and negative. The travel inverter converts this 12 volt DC current into 110v 60hz AC current so you can plug in your electronics that require standard household current to charge/operate.
There is a built in USB port if you device will accept this for 12 volt power. It also has the power oultet with ground for 110v 6hz power.
Link below has a good picture and description. Hope this helps!

The "service" light is on on back of the diehard battery attached to my craftsman garage door opener. How do I service it? Thanks.

It is a sealed lead acid or absorbed glass mat battery, they are unserviceable. I would try and make sure before replaceing that the leads that it is connected to are giving it a charge voltage of 12.6 volts or so, charging mechanize could have malfunctioned. It will also beep when no power is supplied to battery or unit itself, i.e. if power is out or a blown curcuit.

Acts like dead battery, jump starts, and can drive, but turn on the a/c and whole thing dies and I have to coast to parking and jump start again. any ideas?

you need to check the charging system voltage if the alternator is not putting out voltage the car is only running off the battery and the battery is not being recharged turning on the ac adds the drain from the cooing fan about 30amps and the blower motor inside the car another 20 amps and also the compressor clutch of 20 amps

I have a 2004 PT Cruiser Platinum series with a 2.4 liter engine, wjhat is a suitable replacement battery for this car; Sears die hard or interstate ?

Sears Diehard or Interstate would make a battery for your vehicle. Look for something with over 600 cca and you should be ok for the winter.

Diehard makes a Platinum battery, but it costs over $189.99.
Diehard Gold batteries are like $109 or so.

Walmart sells batteries that are comparable to the Diehard Gold for under $100.

However, I just bought a Platinum battery for my 1997 Cadillac Deville Limo and it seems to work alright so far and has a 4 year free replacement warranty.

In general, the more you pay, the better the battery up to the 'best' which is the Diehard Platinum.
Walmart and Interstate do not offer a battery that has as long of a warranty or as good of a design as the Platinum from Diehard which uses proprietary technology to get a better warranty than normal.

The Platinum name in the PT Cruiser has nothing to do with the Platinum name for Diehard, by the way.

Good luck on finding a suitable replacement battery for your 2004 PT Cruiser Platinum.

What's the best battery for a caddillac deville

I put a Diehard Platinum battery in mine for about $189.99 plus tax at Sears Holdings or Sears for short.

It has a 4 year free replacement warranty, the best in the business, and has higher cca's than the Gold version of the Diehard which is equivalent to the best that Walmart sells.

Good luck on buying the 'best' battery for your Cadillac.

Can I replace my ACDelco with a DieHard battery in a 2002 Buick Century, 4 door, 4 cylinder.

Provided that you check and make sure your cranking amps are the same (located typically on top of your battery) that it is the same mount type (top or side (referring to where the cables are mounted to the battery)) and that the battery is the same or very close to the same dimensions (i.e hieght, length and width,) You should have absolutely no problem replacing the battery. When the battery is diconnected do yourself a huge favor. Take a disposable cup, pour in some water and mix in it a few tablespoons of baking soda. When you have done this take each of your battery cables and dip their ends( the ones that connect to the battery) in the solution. This will eliminated any acid build up and help reduce the spread of cable rot (where acid starts to corrode your battery cables) probably not as big a problem for an 02, but deffinitely worth the maintenance. And naturally be sure to dry te cables before reconnectig them.
