Size 357 batteries are silver oxide batteries, while A76 batteries are alkaline batteries. This 1.5-volt size 357 battery is used in watches, medical equipment, laser pointers, and more. The 357 battery is a tiny battery with many uses. SR44W, SR44, SR44SW, 157, 357, 303, SG13, AG13, S76, A76, SR1154Ĭustom labels indicating rechargeable chemistry and battery size The slightly lower output voltage, good capacity, contains mercury, no longer in use The slightly lower output voltage, large capacity used in hearing aid devices To summarize, a comparison of LR44 battery equivalents and replacements are given in the following chemistries cross reference chart: The most common silver oxide equivalents are: LR44 can be also replaced with a silver oxide battery. The most common LR44 battery equivalent batteries are: Please refer to your manufacturers' manuals to determine if the alkaline chemistry will work for your needs.LR44 is an alkaline 1.5 V battery. If you are looking for an affordable, single-use power source that is compatible with your particular device, these LR44 battery choices are the perfect solution. In fact, run times could drastically decline from days to hours if you switch a silver oxide-powered device to an alkaline. Unfortunately, the alkaline cell won't perform as well as the silver oxide, in some electronic devices. Replacing an LR44 battery with an SR44, or vice versa, won't damage your electronic device. Other common names for silver oxide batteries are as follows:īased on this simple comparison, you will see that the SR44 and the LR44 batteries are quite similar - in fact, they are the same size at 11.6mm in diameter and 5.4mm long however, they are not direct replacements for each other. Silver oxide batteries offer a flatter discharge profile that provides more even performance throughout the lifespan of the cell. The silver oxide LR44 battery, on the other hand, may cost more yet offers a more stable voltage, at 1.55V, and therefore a longer lifespan. Here is a list of alkaline LR44 battery equivalents: Another advantage alkaline LR44 battery cells have is that they are more commonly found in brick-and-mortar stores. If you are looking to power low-drain items, such as a blinking light, the alkaline chemistry may be all that you need.
Alkaline batteries offer a more sloping discharge profile - as they are used over time, they become less powerful and your electronic device may not work as well as the first day of a new battery. The alkaline LR44 battery is typically more affordable however, the 1.5 voltage tends to decrease more over time and therefore typically offers a shorter lifespan. This single-use cell is available in two chemistry compositions: alkaline and silver oxide. The LR44 battery is ideally meant for use in small, portable or wearable devices, such as watches, laser pointers, and electronic car keys. LR44 Battery Equivalents Explained What is the difference between SR44 and LR44 batteries? If you're a company or contractor looking to buy a large quanity of batteries, contact our team or create a commercial account for a quote today! Most LR44 batteries are single-use disposable, so we suggest buying in bulk for longterm affordability. Yes, we offer tiered pricing for most of our batteries, letting you save more when you stock up and buy in bulk. You cannot replace CR2032s with an LR44 battery. No, CR2032 batteries use a lithium chemistry and are wider and flatter (like a coin). However, LR44 cells are more widely available and usually cost less. This makes SR44 batteries more ideal for devices like watches and glucometers. While they are the same size, SR44 '357' batteries use a silver oxide chemistry to produce a more stable voltage (1.55V) and a lower self-discharge rate for an increased lifespan. Are LR44s the same as an SR44 or 357 battery? LR44 batteries are often used in small devices like watches, alarm clocks, motherboards, medical devices and more. They typically feature up to 240mAh capacities, have a 1.5V voltage, and are primary (non-rechargeable) due to their alkaline chemistry. The LR44 battery is a alkaline button cell defined by its unique dimensions (11.6mm diameter x 5.4mm thickness).
