The LR754 has a long but not endless lifespan. There will come a time when you have to replace a new one to keep the device running. However, the original product is not always available.
So is there battery LR754 equivalent? The quick answer is yes, and even a lot. Scroll down to sort them all.
Key Specifications And Usage Of LR754
The LR754 is one of the popular alkaline button batteries. It features a small dimension with a diameter of 7.9 mm and a height of 5.4 mm (0.311 x 0.213 inches).
Its nominal voltage is about 1.5 volts but tends to decrease over time. The actual capacity of the LR754 ranges between 44-55 mAh. However, the performance depends on the cut-off voltage between 0.9 – 1.0 volts. Additionally, battery age, temperature, and currents contribute to the output.
You can find these batteries in small electronic devices such as watches, LED flashlights, toys, remote controls, hearing aids, etc. They are cheap and usually sold in pairs.
Because of the unstable voltage, some digital meters or wearable electronic devices occasionally signal a low battery condition when attached to the LR754. Most connoisseurs often prefer other equivalents with different chemistry for their appliances.
What Battery Is Equivalent To LR754?
You can find many similar options for the LR745 replacement, such as LR48, 193, LR750, or AG5. Some other potential alternatives include SR754, SR48, ZA13, PR49, etc., which produce distinctive chemical reactions. They serve you 2-4 years on average.
Some trustable brands you can turn to are Panasonic, Rayovac, Renata, or Varta.
It goes without saying that any 7.9 x 5.4 mm alkaline battery is replaceable for the LR754. Recommended picks include LR48, L750, AG5, and 193. All options are about features and benefits. The variety of labels comes from manufacturers who want their products to stand out the most.
If you want a stable output alternative to the LR754, turn your attention to silver oxide batteries. Potential names include SR754, SR754W, SG5, SR754SW, SR754PW, SR48, 393 and 309. The 309 and SR745W have low discharge, while the 393 and SR745SW feature higher rates.
In comparison, these batteries produce a nominal voltage of 1.55 volts. Their big plus is stable output almost during use. They possess a slightly larger cut-off voltage of about 1.2 volts. The same thing goes for capacity is expected to range between 70-80 mAh.
These items are known for their outstanding reliability, especially for sensitive devices. Some manufacturers recommend them for calculators, watches, or remotes. You can expect these items to stay in good condition for 2-5 years.
Regarding purchase price, they cost more than the LR754. However, the gap is not huge as both are affordable. Now look at the table below for the actual performance of some popular products:
|Models||Capacity||Temperature Range||Self-discharge Rate Per Year||Battery Discharge Current|
|Duracell D309/D393||80 mAh, 15kΩ – 1.2V @20°C||0°C to 60°C||≤10% @20°C||103.3 μA, over 15kΩ @20°C|
|Energizer 193||53 mAh, 15kΩ – 0.9V @21°C||–||–||83 μA, over 15kΩ @21°C & 1.25V|
|Energizer 309||70 mAh, 13kΩ – 1.2V @21°C||–||~2% @20°C||119 μA, over 13kΩ @21°C|
|Energizer 393||75 mAh, 10kΩ – 1.2V @21°C||–||~2% @20°C||155 μA, over 10kΩ @21°C|

|Varta V393 SR48||77 mAh, 13kΩ – 1.2V @20°C||0°C to +60°C||–||–|
Zinc Air Batteries
Recommended labels for this category include 13, Orange Tab, ZA13, 7000ZD, and PR48. These items deliver a slightly lower nominal voltage than the two options above (1.4-1.45 V) but produce several times larger capacity (~280-300 mAh).
As their name suggests, they use oxygen from the air and wet electrolytes for chemistry designation. Manufacturers require users to remove the attached orange tab to prevent overflow into internal construction before use.
After a few minutes, the battery is ready to power devices, usually in-the-ear (ITE) or behind-the-ear (BTE) hearing aids. Once the electrolyte dries out, your component reaches the end of its life even before it is discharged. On the bright side, proper storage allows you to keep this type of battery for 4 years.
|Models||Capacity||Temperature Range||Annual Self-discharge Rate||Current Discharge|
|Duracell Size 13 Orange Tab||300 mAh, 1.5kΩ down to 1.1V @21°C, 50%RH||0°C to 50°C||4 years unactivated @21°C||–|
|Energizer Size 13 Orange Tab||289 mAh, down to 1.05V @21°C, 12/3mA (IEC-STD)||–||4 years unactivated||–|
Safety Issues Of Using And Interchanging LR754 Equivalents
Like other button cells, the LR754 and its equivalents are shiny and attractive to children and pets. They may have confusion and swallow these batteries.
Although the battery cell composition does not contain mercury or heavy metals, undesirable chemical reactions can occur. When electrolytes come into contact with body fluids, they metabolize, causing chemical burns and other internal damage.
Call your doctor or a similar medical service if such an unfortunate situation occurs. Keep calm and act according to instructions to limit bad consequences.
LR754, or AG5 battery equivalent, is available in many chemicals. It is good news for those looking for an alternative to their components.
That said, you should pay attention to the difference in actual voltage, although it is not large. Compare the device’s power needs to see if it can handle such a fluctuation.
