Well, including 7.9mm depth and 3.6mm height lr41 battery comes with a full discharging rate not only to support your device engine but also for a complete nominal storage capacity ranging between 25mAh to 32 mAh to fulfill the monologue of users.

In general, lr41 batteries are often available in Alkaline chemistry out of the manufacturer’s factory, yet a few are available for heavy-purpose in Silver-Oxide or Zinc-Air material. It will be a device drop before shutting off is possible at 1.2V or 0.9V. 

Speaking of the LR41 battery, this is quite heavier yet both SR41 and LR41 are the smallest battery. Most of the LR labeled batteries are made of Alkaline which is often better for mid-sized devices like digital thermometers and BP machines.

If the thermometer ensures LOW or LO, then a threshold temperature user may see. However, this may be considered by the users that the battery is dead, yet the battery is not so and thermometers manual checking should be the first priority. 

SR41 Battery Dimensions and Features 

The counter answer to the question of what is an SR41 battery? One of the most significant batteries for small electrical accessories is the SR41 battery. Features a small round single cell, as well as being popular with 3V button-top alkaline battery. Such a great replacement for the carbon-zinc button cell which consists of 2% AA size. 

Why and how can it replace a carbon-zinc model? Well, the eligibility to prolong an engine life of small accessories contained in this battery with double size rather than a carbon-zinc cell, in fact, the exclusive use of Alkaline you can enjoy throughout the utilization of an SR41 battery. This is a primary solution and if you want an exchange with zinc/zinc chloride monotransistorbutton cells in a wide range of applications. 

The physical dimension of an SR battery is capable of reaching by the manufacturers in several chemistries, for instance, (D x H) 7.9 x 3.6 mm (0.311 x 0.142 inches). There is a basic form of SR41 batteries with high energy density, yet requires high charging conditions including voltage limits and temperature ranges. 

Applications of the several batteries mostly depend on drainage and a cut-off voltage of the gadget, however, a completely dead battery you can recharge. As long as the battery is stronger the current yet the lower the battery capacity will be day by day. 

LR41 Battery Dimensions and Features 

LR41 batteries are very popular batteries, often used, for example, as digital thermometer batteries. If the thermometer says ‘LO’ or ‘LOW’ that means that the measured temperature is below a certain threshold, not that the battery is (almost) dead – just to be sure, always check the thermometer’s manual!

Speaking of the LR41 battery, this is quite heavier yet both SR41 and LR41 are the smallest battery. Most of the LR labeled batteries are made of Alkaline which is often better for mid-sized devices like digital thermometers and BP machines. If the thermometer ensures LOW or LO, then a threshold temperature user may see. However, this may be considered by the users that the battery is dead, yet the battery is not so and thermometers manual checking should be the first priority.

Notes Very constant voltageVoltage drops over timeSlightly lower voltage, yet large capacity andmostly popular for hearing aid batteries

Silver-Oxide:

Not only the label is used for SR41, but also SR736, SR736PW, SR736SW, SG3, AG3, 192, 384, 392, and similarly designed batteries with capacity. However, the dimension cannot be less than 7.9 x 3.6 mm which is identical rather than other material complying batteries. It features a nominal capacity range between 38 to 45 mAh and nominal voltage leads to 1.55.

The output voltage is rather stable than an Alkaline battery whereas the cut-off voltage relies mostly on the device power where we took it into account as 1.2V. Yet this material made SR41 battery we have experienced a little bit of voltage dropper while exceeding ~1.25 volts sharply. 

In terms of talking about the points where we have applied this battery, mostly the construction with low-drain batteries are for hand watches, and similar small devices because it has a low current offer. In contrast, the high-drain featuring ones often carry out the high current for periodical big devices. However, rather than LR41 Batteries, an SR41 with Silver-oxide chemistry in construction is much more reliable and less expensive. 

Alkaline:

7.9 x 3.6 mm dimension intends to support LR41 batteries, as well as similar batteries of LR group such as LR736, AG3 is common in use. In terms of nominal voltage and capacity respectively features with 1,5V and ranging between 25-32 mAh though some manufacturers often claim the batteries with a larger capacity to apply for other purposes. 

However, we have experienced drained batteries using lower currents with the models’ certain capacity. On the other hand, the cut-off voltage is adapted to a maximum of 1V yet often simple devices can operate if the battery reaches 0.8V at once. 

If you are executing long-time services from the LR41 with Alkaline in construction, the support entirely comes from the temperature and storage. As best as we can say, keeping the temperature below 68-77°F (20-25°C) is the smartest idea to get the services properly. 

Zinc-Air:

Apart from the above-mentioned 2 battery chemistry types, Zinc-Air mixed devices offer a real larger capacity which reaches around 180mAh. However, the 1.45V nominal voltage has a short decrease if the battery drainage raises and crosses up to 1.2V sharply. 

Brown tab Zinc-air, we intended to use it in hearing aid batteries because while we tried to remove the battery tab, oxygen entered inside and started the machine. This chemistry is common to ZA312, 312, PR41, 7002ZD, and more. As far as we have tested, zinc-air batteries encountered wet/moist electrolytes. However, after removing the tab, the operating time of the battery remains more than 2 weeks.
