Button/cell Battery Question.

FreedomEclipse · Jun 4, 2019

Maybe im dumb but today i cracked open the key to my bicycle lock. It contained two L1131 button batteries. Since they were the same size and diameter of a single LR44 battery that i had, i replaced the L1131's with them but for some reason. the LED on the key would light up unless i swapped the battery back to the L1131s.

can anyone tell me why this is the case? Maybe the single LR44 doesnt supply enough voltage?? L1131s are 1.55v while the single LR44 is 1.5v ??? but i should still get SOME sort of effect from having half the power right?? I really dont get it.

Well with two L1131 stacked you have 3.1 V.
With single LR44 you have 1.5 V.

Thanks. I thought that was the case.

Maybe some thing like this would work, as their are 3v button battery's but you would have to check more on the size. just not sure if you can get the small ones like that.

Replace the 2, L1131's, (which I presume are Alkaline batteries) with a Silver Oxide replacement.

The Silver Oxide is a much better battery. Silver = AG.

Example: HERE

They also list Silver Oxide's as SR, probably depends on the country. I use them and yeah, they do last quite a bit longer.

They cost a fair bit more though.
