Is it okay to replace the Bluetooth headset rechargeable battery with the same voltage but different

Introduction Is it okay to replace the Bluetooth headset rechargeable battery with the same voltage but different capacity? The internal part of the Bluetooth headset is a 3.7V 150-500MAH lithium-ion battery. Lithium-ion battery is not like nickel-ion battery. cadmium

Is it okay to replace the Bluetooth headset rechargeable battery with the same voltage but different

The Bluetooth headset contains a 3.7V 150-500MAH lithium-ion battery Unlike nickel-cadmium batteries, lithium-ion batteries have a memory effect, so no matter when you charge them, it will not will not affect battery usage. Theoretically, the first three charges and discharges of the battery are like riding in a new car, but personally I don't think the impact is very significant. The lifespan of lithium ion batteries mainly depends on the following three points: 1. Overcharge and overdischarge The normal voltage of lithium batteries is between 3.6-4.2V. If it continues to be used below of 3.6V, its lifespan will necessarily be affected. When the charging circuit fails, the battery will generate heat if the charging voltage is higher than 4.2V, which will also affect its service life. However, current battery protection circuits are very advanced andalmost all have protection against overcharge and overdischarge. 2. High current or short circuit, long calls and battery short circuit cause excessive battery current and heat. It will also affect the normal lifespan. The brand's Bluetooth headset will not heat up the battery during long-term calls. The quality of the battery is good and the circuit is stable and can be within the normal output range of the battery. 3. The battery remains low on power for a long time. Many Bluetooth headset batteries become damaged for this reason. If not used for a long time, the battery will be exhausted. Although the battery protection circuit consumes very little power, the long-term consumption keeps the battery at the normal voltage of 3.6V, causing excessive damage to the battery. A good power adapter and humAmbient conditions have a significant impact on battery life. As long as the author's Bluetooth headset is not discharged or charged, any other usage method will not affect the headset and battery. Don't hesitate to use it.
