Theremostat indicates low battery even with new cells

1

Hi,

Initially and based on your description, it is doubtful if the problem is "shortage or fuse related". To my understanding, your concern is that the "low battery indicator" comes on and off. This indicator although says battery is low actually indicates that the battery is not charging. And the only component in your vehicle responsible for this is the alternator. It could possibly be then that:

belt is slipping (most likely); and/or the alternator is defective (either diode or regulator) (likely)

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

First, even a fully charged battery may not be working right - VERY common.

Does the camera do this on two batteries, one old and one much newer? (I say this because lithium batteries are good for about 500 charges - if you are over this, the batteries will always read weak...)

A service shop can test the camera and see if the battery is reading correctly. A service shop may allow you to try the SHOP's good battery in your camera and see if it reads right. If OK, you need a new battery.

The service shop can reload the operating data into your camera - I have fixed them this way myself.
If not, the circuit board that handles charging and batteries may run you $275 plus labour. (The board is not repairable)

SAFETY FEATURES

Low Battery Warning

Your thermostat has a low battery warning system. When the batteries are detected to be weak, the low battery

warning is indicated by "Low Batt" alternating on the LCD display with the day. You then need to replace the batter-

ies with 2 new AA alkaline batteries. You have 30 seconds to change the batteries before the settings are lost.

Error Mode

If the thermostat is unable to control your system due to

an unexpected problem, the thermostat will enter Error

Mode. In this condition, the thermostat flashes "Error"

and a code number on the LCD display, and shuts off

your system.

To correct this problem, replace the batteries with 2

new AA alkaline batteries, even if you have recently

replaced them. Next, use a paper clip to press the RE-

SET button next to the keypad. You will need to repro-

gram your thermostat and confirm normal...

Leave the batteries out for 5 minutes and try again. If it still does not reset and comes back on, you need a new thermostat. I know this answer is short and sweet, but these thermostats are notoriously bad for losing their display. If turning the system switch to "Off" and putting the batteries in backwards doesn't work, the next step is to remove the batteries for a period of time and try. If that doesn't work, its gone. There is nothing else you can do.

Customer: I just tried to remove the thermostat from the wall - it's still readying battery low even with the new batteries.

Matthew: The installation instructions say to take the batteries out and leave them out for 1 hour when it does this. Most times - 5 minutes is all it takes, but if they want an hour - try an...

Many times a reset button needs to be pressed with a paper clip etc, to restore operation after replacing the battery. Check the manual.

UltraBattery is a hybrid energy storage device invented by Australia’s Commonwealth Scientific and Industrial Research Organisation (CSIRO). UltraBattery combines ultracapacitor technology with lead-acid battery technology in a single cell with a common electrolyte.

Introduction[edit]

Research conducted by independent laboratories, such as the United States's Sandia National Laboratories,[1] the Advanced Lead-Acid Battery Consortium (ALABC),[2] the Commonwealth Scientific and Industrial Research Organisation (CSIRO)[3] and commercial tests by East Penn Manufacturing, Furukawa Battery and Ecoult indicate that in comparison with conventional valve regulated lead acid (VRLA) batteries, UltraBattery technology has higher energy efficiencies, a longer lifetime and superior charge acceptance under partial state of charge (SoC) conditions.

Combining the two technologies in one battery cell means that UltraBattery works very efficiently compared with conventional lead...

Hi.

I am using my hp33s scientific calculator (RPN/ALG-calculator) for several years and now there is a strange error.

After using up old batteries I was not using the calculator for more than two months. Then I bought new batteries and inserted them. Just after this the "low battery" warning showed up and the calculator turned off. I tried to restart him several times and reseted him, but nothing helped, the "low battery" warning always appeared and then it turned off. After some failed starts the batteries lost their whole energy. And this in only 3 days!

I bought new batteries and the same happend again.

I think this is a calculator error. Maybe there is even a short circuit somewhere? But the calculator never fell on the ground.

Do somebody know, what I could...

Speak out for your right to repair.

New York,

New Yorkers stand up for what they believe in. And we're asking you to stand up for repair.

This year, New York could be the first state in the nation to pass the Fair Repair Act, A8192 and S618. We have a chance to guarantee our right to repair electronic equipment—like smartphones, computers, and even farm equipment. We have a chance to protect local repair jobs—the corner mom-and-pop repair shops that keep getting squeezed out by manufacturers.

It’s not going to be easy. Manufacturers are standing in the way. When your stuff breaks, they want to be the only people allowed to fix it. So far, they’ve managed to stop Fair Repair legislation before your representatives get a chance to vote on it. We’ve got to be louder than their lobbyists.

The Fair Repair Act, known as A8192 and S618, requires manufacturers to provide owners and independent repair...

Dead cells are not really "Dead" in the human sense, the are slightly conductive AND have high resistance, small currents (voltage) still flow through these cells, however each contributes little or nothing to the "Amp" capacity of the battery. Each cell delivers about 2.0 V DC (more or less), so 6 cells x 2.0V = 12.0 Volts. Each healthy cell can produce 60 Amps (more or less) depending on the number of plates in each cell. What the battery has is one or more really weak cells (dead) and these cells hold what is known as a "surface charge". A volt meter will read 12 volts on the battery at "rest" (no load), but as soon as a substantial load is applied, the voltage drops very low or zero. This is why small interior lights might come on, but when the starter is engaged, the battery voltage drops very low and the battery produces almost no Amps. It takes all 6 cells working to produce the required amps. Amperes or Amps is a measure of the volume of electrical...

Wow, I really appreciate all the thank you messages!!! Really wasn't expecting such a big response!! Very glad to be of help. I do plan on doing some more testing as I still have a few unanswered questions about how this device handles power. It would be awesome if people can share their experiences with this mod. I'm guessing most of you guys out there with a RX200 were just as annoyed with the lack of solid information regarding charging and battery management on this mod. I'm well chuffed to be able to add to the knowledge base and hopefully this knowledge can allow us all to vape safer and get the most out of our mods. After all, the RX200 even with it's not so great internal charging is still an awesome bit of gear!

I'll attempt to answer some questions from the comments, please forgive me for not linking comments, I'm a total reddit newbie and have no idea how to yet! I'll try to make it clear when something I say is speculation or an educated guess without testing. My...

We all like getting new phones, right? In all the excitement of a new cell phone, many consumers forget about the battery. After all, the battery is just the thing you throw into the cell phone to make it work – why must we worry about it instead of playing with our new bazillion inch touchscreen? The thing about the battery, though, is if you condition it properly when it is new, it will last longer and last stronger; and since no one likes to have to recharge their cell phone midday, giving the battery its due rights at the beginning is in the best interest of all of us.

New batteries need conditioning. (No, not the conditioner you use in the shower.) By “conditioning” I mean properly initializing them so they hold as full of a charge as possible. How to condition the battery depends on what type of battery it is:

Nickel-Cadmium – NiCad batteries are often found in older, “dumb” phones. NiCad batteries have a “memory” that consumers need to “train” to make the battery...

HP-37E "low" battery
Message #1 Posted by Michel Beaulieu on 26 Feb 2004, 4:28 p.m.

My HP-37E works and look like new but even with brand new batteries, the red LED indicating low battery is always on. The calculator recently develop this problem after i dissambled the calculator and ressambled it. After i realize the problem, i open it again and clean every contact but always the false warning. All the display is crispy bright LED so i'm sure the calculator don't miss power. Can it be a discrete components one the power supply board? Which one? I remember someone here told me to ajust a small potentiometer on My HP-25 that has the same problem and it solve the problem but as i look on the 37E, no ajustement screw on this...

A battery is a device that creates electrical energy by means of chemical reactions. There are two types of batteries: wet cell and dry cell. A wet cell battery operates by means of a liquid electrolyte solution, while in a dry cell battery the solution is in the form of a paste. Some wet cells can be recharged, while others are only good for a shorter period of time. Eventually, however, all such batteries become unusable and have to be replaced.

Different Types

There are a number of different types of wet cell batteries, categorized as "primary" or "secondary." A primary battery can be used only until its chemicals are exhausted and cannot react with each other anymore. In contrast to this, a secondary battery can be recharged by effectively reversing the internal chemical process used to generate a charge.

Composition of Some Batteries

Most automobiles use a wet cell battery. The lead acid battery, often found in such vehicles, is a secondary...

Portable iPod charger that you can use while away from your computer. The circuit is based around an MC34063 switchmode regulator. This has high efficiency so that there is very little heat produced inside the box, even when delivering its maximum output current. The circuit is more complicated than if we used a 7805 3-terminal regulator but since the input voltage could be 15V DC or more, the voltage dissipation in such a regulator could be 5W or more at 500mA. and 5W is far too much for a 7805, even with quite a large heatsink.


Batwatch is a simple monitor for a solar panel battery charger, using an Atmel ATtiny13V. It periodically measures the charge current and battery voltage, and shows them by blinking two LEDs. I built this circuit into the plug of a VW solar charger panel that is used to prevent a discharge of the battery when a car is not used for some time. A modern car contains a large amount of electronics, and a quiescent current of 40-50mA...
