Aa lithium batteries for smoke detectors10/12/2023 ![]() It then showed a low voltage of like 0.6v, and then it was able to charge in the USB charger.Īfter this charge, it now measures a voltage of 4.05v. I finally got it to do something by wiring it to a power screwdriver and running it for a few seconds. Additionally, the National Fire Protection Association. It’s recommended to replace smoke alarms with 10 year lithium powered batteries at least once every 10 years. It would show a voltage of 1.5v but would not charge or discharge. Although smoke alarms with 10 year lithium powered batteries are designed to last for 10 years, it’s important to test them regularly and keep an eye on the expiration date. (emphasis in original) While they work fine with other quality alkaline batteries from reputable manufacturers, I'm curious as to why the manual specifically forbids the use of lithium batteries. ![]() NOTE: Do not use Lithium batteries in this unit. It would not discharge on my Opus charger. Use of a different battery may have a detrimental effect on the alarm operation. However, it would show full on the USB charger and would not charge. This particular battery would continue to show 1.5v on measurement. Can provide power for Kidde devices for up to 2 years. When I was doing some charge and discharge cycles, one of the 4 exhibited some quirky behavior:Īfter a particular discharge cycle, it would not turn fully off, like the other 3 batteries would (they would go completely dead and show 0v on a multimeter and would need to be jumped back alive). Kidde batteries are suitable for all Kidde smoke and carbon monoxide alarms. My smart charger, Opus BT-C3400, can charge NiMH and Li-Ion batteries, but not these 1.5v Li-Ion batteries, which I assume is because of their non-standard voltage. They are charged using USB chargers which provide 5v to the battery. ![]() However, they have a tiny circuit board in there to step down the voltage to 1.5v steady, to be used in most consumer devices.Ĭapacity is rated at 3400 mWh, not that different from good NiMH batteries. Inside, they have a lithium-ion rechargeable cell, and this chemistry should produce 3.7v. This category of batteries seems like pretty interesting tech, based on teardown videos on youtube. I bought a set of 4 Deleepow 1.5v rechargeable lithium AA size batteries, from Amazon.
