Most of the everyday appliances people use today operate on rechargeable lithium-ion batteries. These include pacemakers, solar power storage equipment, laptops, and mobile phones. Lithium iron phosphate batteries are the latest addition to the lithium-ion battery family.
They are safer, have higher performance and cost less than most lithium-ion batteries. Extending the life of your lithium iron phosphate battery to get the most out of it is vital. Here are some care tips to extend your battery’s life.
1. Opt for partial-discharge cycles
Using 20–30% of your battery’s capacity before recharging it will boost its cycle life. In general, 5–10 shallow discharges amount to a full discharge cycle.
Though there might be multiple partial-discharge cycles, maintaining your battery at a full charge shortens its battery life. You should hence avoid full discharge cycles as much as possible.
2. Choose the right charge termination method
The charge-current termination you select also has an impact on your battery’s life. Choose a charger that uses the minimum charge-current termination since it does not charge your battery to 100%, hence extending its life.
Choosing a current charge termination of C/5, for instance, reduces your float voltage to approximately 4.1V and charges your battery to about 85%.
3. Avoid deep discharges
A very deep discharge (less than 2–3V) quickly and permanently damages your lithium ion battery. This is because in most cases, it causes internal metal plating leads to a short circuit and renders your battery unusable. Experts recommend not discharging a lithium ion battery at a voltage of less than 2.8V.
Lithium iron phosphate batteries are fast becoming an industry standard for rechargeable batteries. With proper care, your battery can last for 5–7 years as opposed to others with a life expectancy of 3–4 years.
