Precautions for Using Lithium Battery
 
01/

Prevent overcharge and discharge
Excessive charging and discharging of lithium batteries will lead to the degradation or even damage of battery performance. Therefore, when using lithium batteries, excessive charging and discharging should be avoided, which can be achieved by reasonably setting the charging and discharging voltage range and using protective circuit boards.

02/

Avoid overheating
Overheating of lithium batteries can cause safety hazards, and even fires and explosions. Therefore, when using lithium batteries, over charging, over-dipation and long-term high-load use should be avoided to control the battery temperature within a safe range.

03/

Avoid short circuit
The short circuit of lithium batteries will lead to excessive current, causing fire and explosion. Therefore, when assembling and using lithium batteries, metal objects or conductive objects should be avoided from touching the positive and negative electrodes of lithium batteries to avoid short circuit.

04/

Prevent vibration and impact
Lithium batteries should be avoided from severe vibration and external force during assembly and use to avoid damaging the structure and performance of the battery. Appropriate fixing and buffering measures should be taken in applications such as mobile devices and electric vehicles.

05/

Pay attention to storage conditions
Lithium batteries that are not used for a long time should be stored in a dry, ventilated and suitable temperature environment to avoid too high or too low temperature and humidity.

06/

Handling abnormal situations
When there are abnormal situations of lithium batteries, such as heating, smoke, leakage, etc., they should be stopped immediately and properly handled. Do not discard or dispose of abnormal lithium batteries at will and should be handled in accordance with relevant regulations to avoid safety accidents.

 

Storage Conditions of Lithium Battery

 

Temperature is vital for understanding how to store lithium batteries. The recommended temperature for lithium-ion battery storage for most varieties would be ideally 15°C (59°F), a moderate area that isn't extremely hot nor extremely cold–but that's not the case across the board. So, before storing lithium batteries, thoroughly read labels on proper temperature for your specific battery type.

 

Placing your batteries in a temperature-controlled room would ensure safe regulation. Lithium battery storage buildings with climate control are ideal for storing bulk quantities of Li-ion batteries at specific temperatures to ensure a safe storage environment.

FAQ

Q: What type of lithium battery is best for home solar energy storage?

A:LiFePO4 (Lithium Iron Phosphate) batteries are the top choice for residential use. They feature ultra-high safety, stable chemical structure with no thermal runaway risk, long cycle life (6000–8000 cycles), low self-discharge rate and round-trip efficiency over 92%, far superior to ternary lithium and lead-acid batteries for household solar backup applications.

Q: Are home wall-mounted lithium batteries safe for indoor installation?

A:Yes. Our residential lithium batteries adopt LiFePO4 cells plus built-in intelligent BMS system, which monitors cell voltage, current and temperature in real time to prevent overcharging, over-discharging, short circuit and overheating. With flame-retardant casing and sealed structure, they can be safely installed indoors, garages and dry balconies.

Q: How much battery capacity do I need for my household?

A: Basic demand (lights, refrigerator, WiFi): 5kWh–10kWh

Daily self-consumption + short power outage backup: 10kWh–15kWh

Whole-house power backup & air conditioner operation: 15kWh–30kWh You can calculate based on your daily household electricity consumption and backup duration needs.

Q: Can the home lithium battery work with my existing solar panels and inverter?

A:Nearly maintenance-free. No water replenishment needed like lead-acid batteries. You only need to check whether terminals are loose or rusty every 6 months and wipe the shell with a dry cloth to keep it clean and ventilated.

Q: Can the battery store solar energy for use at night or during power cuts?

A: Yes. The battery stores excess electricity generated by solar panels during the daytime. After sunset or when the grid fails, it automatically discharges to power household appliances, greatly cutting electricity bills and providing reliable outage backup power.

FAQ

Is professional installation mandatory for residential lithium batteries?

We strongly suggest installation by certified solar electricians. Improper wiring, polarity reversal or mismatched inverter parameters will trigger safety hazards and void the warranty. We supply detailed installation manuals and remote technical support for installers.

How should I store the lithium battery if it is not used for a long time?

Maintain the battery SOC at 40%–60%, store it in a cool, dry and ventilated place. Recharge the battery once every 3–6 months to avoid excessive self-discharge and extend service life.

Will household lithium batteries gradually lose storage capacity over years of use?

Capacity attenuation is inevitable yet very mild for LiFePO4 batteries. After 10 years of regular daily use, the usable capacity will still stay above 75% of the original rating. Gentle charging and avoiding deep discharge frequently can effectively slow down capacity degradation.

Can residential lithium batteries be applied for both grid-tied and off-grid solar systems?

Our home lithium batteries are dual-purpose. They work smoothly with grid-tied systems to save electricity costs by storing surplus solar power, and also adapt to fully off-grid households without public grid access for round-the-clock independent power supply.

What makes lithium iron phosphate batteries better than traditional lead-acid batteries for home energy storage?

LiFePO4 batteries boast 5–8 times longer cycle life, lighter weight, smaller footprint, no corrosive liquid leakage, zero memory effect, higher energy efficiency and far lower long-term replacement costs compared with lead-acid batteries.

Will residential energy storage batteries produce loud running noise during charging and discharging?

No obvious noise is generated during normal operation. Only the tiny built-in cooling fan will make faint airflow sound under high-load working conditions, which will not disturb daily rest and indoor living.

How to properly dispose of expired or defective household lithium batteries?

We advocate standardized recycling. Expired batteries shall not be discarded casually. You can deliver old batteries to local professional lithium battery recycling institutions; we also provide bulk recycling cooperation services for our global distributors.
