IMPROVE LiFePO4 Lithium Boat Battery
Application
This documentation specific basic performance, technical requirement, testing method, warning and caution of the LIFEPO4 rechargeable battery.
Common fault judgment
Solutions to general failures of lithium iron phosphate batteries:
| Fault conditions | Solution |
|---|---|
| The battery pack cannot be charged and discharged normally | 1 )Check if the |
line connection is correct
2)Check whether the battery pack voltage is normal
3)Check for loose battery connections
4 }Turn off the load and then turn it on again
5)Replace the protective plate
The battery heats up when in use| 1 )Continuous working current is too large
2)The connection between the batteries is not tight
Battery operating instruction
-
Charge
Charge current: Never out of the max charge current as mentioned in specification.
Charge voltage: Never out of the max charge voltage as mentioned in specification.
Charge temperature : Please refer to the temperature range as specification.
Charge as constant current before constant voltage, Never reverse charge the battery. -
Discharge current
The discharge current is not allowed to out of max current as specification.
Otherwise, the battery will be over heat and capacity fading. -
Discharge temperature
Please refer to the temperature range as specification. -
Over-discharge
It’s workable if over charge and discharge for a short while but not allow to do it for a long time. over discharge may result in self-energy disappear. Please keep a certain electric quantity to prevent over discharge.
Battery maintenance
-
After completing the installation of the battery according to the installation manual, before the battery is discharged for the first time, the battery should be fully charged before use. After the battery is fully charged and discharged 3 to 5 times, the battery can reach its maximum capacity.
-
When the battery power is insufficient, it should be charged in time, which will help prolong the battery life. If the battery is not charged in time, leaving the battery in a state of power shortage for a long time will affect the service life of the battery. If the battery needs to be put on hold for a long time, it is best to leave the battery in a half-charged state, and charge the battery once every 2 months, and the charging time is one hour.
-
The battery should be installed in a well-ventilated, dry and clean environment; when charging, avoid fire sources and flammable items from approaching and disconnect the load (turn off the electrical equipment).
-
The working environment temperature of the battery is 5-40 ·c (the best working environment temperature is 15-35 C ). If it is outside this temperature range, the performance of the battery may change. The intuitive expression is that the battery capacity changes.
Or the device runtime varies, which is normal. -
Do not use organic solvents to clean the battery case. When an accidental fire occurs in the battery, carbon dioxide cannot be used to extinguish the fire, but a fire extinguisher such as carbon tetrachloride or sand should be used to extinguish the fire.
-
The battery is a consumable item, and the life of the battery is limited. Please replace the battery in time when the battery capacity is lower than 80% of the rated capacity.
Precautions for use
In order to prevent accidents such as battery leakage, abnormal heat generation, fire, performance degradation, explosion, etc., please use the battery correctly according to the following specifications. The company is not responsible for any accidents caused by not following the instructions in this manual.
- Handle with care to avoid violent vibration.
- Do not immerse the battery and its accessories in water or other liquids, and pay attention to moisture.
- Short circuit of the positive and negative output terminals of the battery pack should be avoided.
- It is forbidden to disassemble the battery. Removing the battery may cause an internal short circuit, causing internal decomposition, fire, explosion, etc. In addition, disassembling the battery may leak the battery electrolyte; if any electrolyte spills on the skin, eyes or other parts of the body, immediately rinse with water and see a doctor immediately.
- It is forbidden to throw used batteries into fire, otherwise dangerous accidents such as explosion will occur.
- If the battery is damaged, deformed, leaking electrolyte or smells peculiar smell and other abnormal phenomena, do not use the battery again; please send it to the authorized office of the manufacturer or relevant institutions for proper disposal. In addition, batteries leaking electrolyte should be kept away from fire sources to avoid explosion.
- Battery replacement. The battery should be replaced and installed by the battery supplier, and the user is not allowed to replace it without authorization.
- Unauthorized disassembly is prohibited. Users are not allowed to disassemble the battery pack and charger without permission, otherwise, our company will not be responsible for the loss caused by this.
Transportation precautions
- The battery pack is suitable for transportation such as automobiles, trains, and airplanes, but the sun, rain and severe vibration should be avoided during transportation.
- The battery pack should be packed with insulating and shockproof materials, and marked with a label with the word “fragile” to avoid damage to the battery pack caused by bumps on the way.
- The pole of the battery pack should be upward, and the upward label should be marked. Do not put it upside down, sideways, etc.
- The battery pack must be handled with care during transportation, loading and unloading. Do not throw it at will to avoid collision.
- Do not put heavy objects on the battery pack during transportation to avoid damage to the battery pack caused by squeezing.(6) Do not mix and transport with flammable, explosive and sharp metal objects.
Storage
The battery should be stored in a clean, dry and ventilated environment with a temperature of 5 C ~+40 C and a relative humidity of S90% (40 C ±2 C ). Avoid contact with corrosive substances and keep away from fire and heat sources. And the battery should be in a half-charged state of about 50% to 60%. To prevent over-discharge of the battery, charge the battery for about an hour every 2 months.
Warranty period
Quality assurance for contractual stipulation against manufacturing defects, but. we are not responsible for the damage caused by inadequate and improper use. The information (subject to change without prior notice ) contained in this document is for reference only and should not be used as a basis for product guarantee or warranty. For applications other than those described here, please contact our office. Manufacturer reserves the right to alter, amend the design, model and specification without prior notice.
Other Chemical Reaction
The battery performance will reduce if over time using or unused for a long time due to it’s a reaction of chemical. In addition, the battery life will be shorten or injury or damage itself from electrolyte leakage, heating ignition or explosion for improper handling. It’s necessary to replace battery if unable to charge even with proper way.
How to use batteries in series and parallel
Make sure the batteries are of the same voltage before connecting in series or parallel. It is recommended to charge separately when charging
