Rsfjr87 ( talk) 17:29, 2 December 2021 (UTC) Reply please improve article The worst case scenario is that you can damage the equipment. The best case scenario is that your battery is going to deplete much faster and you gonna lose calibration if used in calibration equipments. So, besides the lower charge capacity of LR batteries (120/150 mAh), it won't pose any risk for the equipment, but it WILL affect the calibration of measuring equipments/apparatus.Īs for the MR batteries, it's another story, even if it has the same capacity of an SR battery, the output voltage is much less (1.35~1.40V), so using an LR/SR battery in a equipment designed for MR batteries might cause malfunction or damage, since the power dissipated by components inside the equipment will be about 20~30% more. The most posed problem by swapping those batteries yields in the electronic apparatus you are going to use, for exemple, my Nikon FM2 is designed to use SR44 batteries, since where I live is hard to find them, I use LR44 anyways, it does not pose a risk for my equipment, but the camera light meter was calibrated to operate with the SR44 1.55V, so by using LR44 I know the exposure meter will be off by about 4%, which does not affect the quality of pictures I take. The thing is most of pre-90's devices were designed for SR44, because the use of lithium batteries back in the day were not that popular. The opposite is the same LR44 used in the place of a SR44 reduces de power dissipation for about 7%. (1.55)²/(1.50)² = 7% power dissipation increase within the components, which falls vert well within the range of the electronics circuitry, some most of capacitors have 10%+ tolerance, for example. Can you find any WP:RS for this?

DieSwartzPunkt ( talk) 11:39, 24 July 2012 (UTC) Reply An interesting anecdote. MR44H were 1.4v as against 1.35v for regular mercury batteries (and they were cheaper because they had no tax on the price as they were designed exclusively for hearing aids). It rapidly became known that it would not work with the cheaper MR44H batteries (indeed it would never work again if tried). There was a pocket computer around in the late 1970's/early 1980's that used 4xMR44 batteries. The article need to reference SR44 batteries because of the redirect from SR44. Some may work with the SR44 but there is no way to know for sure and trying it is not a good idea. Voltage: 1.5v dc Execution: buttons, alkaline battery 1.5V, conoflick design Batteries with marking LR44 or also AG13, G13, 303, 357, 1128MP, 1130SO. There are plenty of devices around that are designed to work with the LR44 battery. However, the terminal voltage of the SR version is a tad higher (1.55v -v- 1.5v) and its capacity is also higher. A product designed for an SR44 battery will not work well if you substitute an LR44. SR44 and LR44 have a very different discharge curve. Tiki God 15:33, 23 July 2006 (UTC) Reply ĪFAIK, this article (where it says that SR44 and LR44 are considered the same) is incorrect and so is the list of battery sizes article with the same misinformation. Someone who understands naming/rerouting better might want to change this article to SR44 battery and have LR44 point there.
LR44 BATTERY SERIES
The LR series are only used when price is a major consideration such as the demo batteries that come free with a device.
Batteries worked.IEC LR series batteries have been used longer, but currently IEC SR series batteries are more commonly used in watches and electronic devices. I was surprised at how quickly I had received my batteries! And they are interchangeable with all of my products.
Posted by Yvonne M Gleason on 25th Sep 2021 I received my batteries much sooner than I thought I would. The batteries are some I ordered a long time ago ad just took a chance that I could still order. Otherwise the product is great and reasonably priced. Don't know whats going on with the mail, but that was a long time.
I didn't get this order until Friday January 7, or Saturday January 8, 2022.
