What battery is equivalent to LR621?

Due to their superior performance in various modest everyday equipment, LR621 batteries have become quite popular. The LR621 and other coin cell batteries are used in watches, remote controls, miniature toys, and other small gadgets. You can find these batteries on the market for a reasonable price. Several well-known companies now manufacture the LR621.

LR621 is an alkaline battery and has many replacements and equivalents. However, the best match is the SR621. It is almost the same as the LR621, but it is a silver oxide battery with steady voltage and high capacity. Other alternatives for the LR621 battery include SR621SW, SR60, T, SR621, SB-AG/DG, 280-34, V364, D364, 602, S621E, GP364, AG1, AG-1, L621, SG1, LR60, LR620, and more.

What is the LR621  battery?

LR621 are Non-rechargeable button/coin cell batteries with physical attributes of 6.8 mm in diameter and 2.1 mm in height. Their nominal voltage is 1.5 volts, but the voltage drops rapidly as the battery is utilized. The cut-off voltage is typically 0.9 volts. However, if these batteries are used in electronic devices, the gadget may have its own ‘own’ cut-off voltage, such as 1.1 or 1.2 volts; when the battery hits this level, the equipment either shuts down or begins to behave erratically. The nominal capacity of LR621/LR60/AG1 batteries is roughly 12-15 mAh. LR621 batteries are commonly used in toys, flashlights, and other devices where a steady voltage is not required.

What is the SR621 battery?

Silver-oxide batteries (SR621) have a nominal voltage of 1.55 volts and a cut-off value of 1.2 volts. When the battery is in use, the voltage lowers significantly before becoming constant. The battery voltage declines sharply as the battery is being depleted, and the battery is regarded as fully discharged when it falls below 1.2 volts. The battery has a nominal capacity of 18-23(25) mAh. Silver oxide batteries have a bigger capacity, more steady operating voltage, higher cut-off voltage, and long shelf life and are slightly more expensive when compared to alkaline batteries.
