How to choose the phone battery supplier?

Lithium batteries are divided into lithium-ion batteries and lithium polymer batteries. Lithium-ion batteries use a liquid electrolyte, while lithium polymer batteries use a solid-state electrolyte. As a result, lithium-ion batteries are less stable than lithium polymer batteries. If subjected to external impacts or charged with non-compliant chargers, they may explode. Many portable electronic devices, such as smartphones, laptops, and digital cameras, use lithium batteries. Purchasing low-quality lithium batteries is like placing a "time bomb" near yourself. Therefore, consumers must pay attention to the following points when selecting lithium batteries

How to Choose the Right Lithium Battery

1. Clear Capacity Labeling
Lithium batteries without clearly marked capacity (e.g., 2200mAh or 4400mAh) are likely made from inferior or recycled battery cells. Many cheap lithium batteries on the market use recycled or salvaged cells. While they may be inexpensive, they have a short lifespan, unstable quality, and may damage devices or even explode if mishandled.

2. Guaranteed Standby Time
Standby time refers to the continuous usage duration from when the battery is installed in a device until the next recharge. Most lithium batteries sold in the market cannot guarantee standby time due to inconsistent quality. Many low-cost batteries use poor-quality cells, resulting in very short standby times.

3. Built-in Safety Protection Circuit
The nature of lithium batteries requires an additional protection circuit to prevent overcharging, over-discharging, and short circuits. Lithium batteries without protection circuits risk swelling, leakage, or explosion. Due to fierce price competition, some manufacturers use cheaper protection circuits or omit them entirely, leading to the proliferation of potentially explosive batteries. Since consumers cannot visually determine whether a battery has a protection circuit, it is best to purchase from reputable sellers.
