A genuine SR44 or 357 cell is hard to find, and the alkaline LR44, which is the same size button, and same nominal voltage, is very common and easy to find. Be careful: most retailers don't know the difference between LR44 (alkaline) and SR44 (silver oxide) and act like they are interchangeable, when they aren't.
Also, is lr41 same as 392?
These work great in my pointer; and are exactly same size as LR41 that they replace. Comments about Duracell 384/392B Watch Battery (SR41, GS3, G3, LR41): The 384/392 button is significantly larger than the space for an LR41.
What battery is the same as lr41?

Medic Batteries carries the Energizer 357/303 battery, an AG13 equivalent battery. The Energizer 357/303 replaces all AG13 button cell batteries, which are used in watches, medical equipment, laser pointers and more.
Button Battery Safety. More and more household items have button batteries (Picture 1). These items include: remote controls, thermometers, games, toys, hearing aids, calculators, bathroom scales, musical greeting cards, key fobs, electronic jewelry, holiday ornaments, cameras, and candles.
Power source for thousands of electronic devices: watches, key fobs, LED lights, calculators. AG13 replaces type LR44, G13, A76, GP76A, 357 & SR44W batteries. High-quality long-life alkaline button-cell batteries at huge savings to name-brands sold in stores.
↑ When stored at room temperature (i.e. 70°F/ 21°C), cylindrical alkaline batteries have a shelf life of 5 to 10 years and cylindrical carbon zinc 3 to 5 years. Lithium Cylindrical types can be stored from 10 to 15 years. Prolonged storage at elevated temperatures will shorten storage life.
An electric battery is a device consisting of one or more electrochemical cells with external connections provided to power electrical devices such as flashlights, smartphones, and electric cars. When a battery is supplying electric power, its positive terminal is the cathode and its negative terminal is the anode.
For example, primary (non-rechargeable) alkaline batteries have a nominal voltage of 1.5 volts. Rechargeable NiCd (nickel cadmium) and NiMH (nickel metal hydride) typically output 1.25 volts per cell. Dry Leclanche (carbon-zinc), alkaline and lithium batteries are the most common modern types.
Fully charged automotive batteries should measure at 12.6 volts or above. When the engine is running, this measurement should be 13.7 to 14.7 volts. If you don't have a multimeter to tell you the voltage of your battery, you can do a test of your electrical system by starting the car and turning on the headlights.
The best way to check battery charge is with a digital voltmeter. A fully charged battery should read 12.65 volts. A reading of 12.45 volts equals about a 75% charge and is good enough for further testing. Anything less means the battery is low and needs to be recharged.
All you need to perform the test and check if your alkaline batteries are juiced is a hard surface. Drop each battery (with the flat, negative end down) from a couple of inches up. If the battery is charged, it should make a solid thud and most likely stay standing.
Introduction: Test the Strength of a 9V Battery With Your Tongue. First inspect the battery for any noticeable signs of degradation, rust, battery acid, etc. If the battery seems reasonably clean, stick it to your tongue. You will feel a slight jolt and metallic taste.
A car alternator needs to be putting out at least 13-14 volts (ideally between 13.8 and 14.2 volts) to effectively charge a 12 volt car battery. If the alternator is putting out too much voltage (15+ volts), it is likely your battery acid will boil over out of the battery.
If jump starting gets your engine started and running, but the car will not start again once you turn it off, the battery is probably the problem. In this case, the alternator is doing its job of keeping the battery going once it has been jumped, but the battery can't hold a charge when the alternator is shuts off.
6 Symptoms of a Failing Alternator
- The indicator light. It's quite likely that your vehicle is equipped with a warning indicator light in the dashboard titled "ALT" or "GEN."
- Headlights are dim or flickering.
- Other electrical failures.
- Strange noises.
- Car stalls or has difficulty starting.
- Battery dies.
Waits says the average price to replace an alternator with a remanufactured one is $400, while Gunning adds that a remanufactured alternator on a typical, domestic car, costs about $300 to $500, including parts and labor. The price of a new alternator can run from $500 to $1,000.
Yes , a car will run with a bad alternator……until the battery goes dead. Yes but eventually the car will die when the battery no longer has power to run the spark plugs and other systems. If you shut the car off , it will likely not start again without a jump start.
Defective alternator diode. A car alternator recharges the battery and powers certain electrical systems. If your alternator has a bad diode, your battery can drain. The bad diode can cause the circuit to charge even when the engine is shut off, and you end up in the morning with a car that won't start.
One of the most common failures is bearing failure. The needle bearings that allow the rotor to spin freely inside the stator can break down from dirt and heat. When the bearings fail, the rotor will not spin efficiently and can eventually seize. Usually an alternator with bearings failure makes a loud grinding noise.
Odd sounds. There are many different parts that spin inside your vehicle's alternator to produce electrical current. If one of these parts becomes worn or breaks, this could cause a grinding or whining noise. Specifically, worn out bearings inside the alternator have been known to cause this type of noise.
It keeps the battery continuously charged and the car's electrical and computer systems up and running. The alternator works about as hard as any part of your car, so eventually it is bound to fizzle out. The average longevity of an alternator is seven years, or about 150,000 miles.
