All mobile phones depend on a lithium-ion battery to operate. Batteries are rechargeable and must be plugged in after the drain for phones to operate. Usually, a lithium-ion battery in use should last between 2 to 3 years. Nowadays, all mobile phones are using lithium-ion polymer batteries. A lithium-ion polymer battery is a rechargeable battery of lithium-ion technology using a polymer electrolyte instead of a liquid electrolyte. The two important parts of a mobile phone battery are the battery cell and protection board. Damage of the battery cell or the protection board will result in your mobile phone not charging/turning on. And the battery capacity will affect the standby time of the mobile phone.
Overcharge, over-discharge, short-circuit, etc. will result in a swollen battery cell. Protective start-up failure caused by poorly performed protection board may result in battery damage, smoking, fire, explosion, etc..
Notice: A production-finished battery cell should be protected from short-circuit, high temperature, impact, drop, overcharge, over-discharge, etc.. Users should use chargers from a regular manufacturer to charge the phone (the charging voltage should not exceed 4.2V). And the operating temperature should not exceed 45℃. Don't put the battery together with conductors like keys to avoid external short-circuit. Protect the battery from collision, external physical damage such as drop and squeeze, impact, overcharge, and over-discharge which are probably to cause explosion.
It’s necessary to choose high-quality batteries. Low-quality batteries do have bad effects on your phone, even your health. Treat it carefully when you decide to replace your battery.
Harm Effects of Low-Quality Batteries
Small capacity means short service life. Short battery cycle life leads to a faster charge decay. And that’s why the batteries need to be replaced frequently. Battery volume indication error, insufficient discharge, and cliff-like power drop may lead to auto power-off. High internal resistance increases the heat and power consumption. What’s more, the increasing temperature brings potential security risks. Low-quality protection board may cause identification failure, connection failure and power indicator error. Protection board temperature measuring error makes the phone unable to have an accurate response to temperature changes, which can also damage the phone. Why You Should Choose REW Batteries
