How long does it take to fully charge a Geely Boyue battery directly?
4 Answers
After the Geely Boyue battery runs out of power, it takes 20 hours to fully charge it directly. It is recommended to purchase a dedicated charger for charging to avoid affecting the normal use of the battery. Constant current and limited voltage: For example, when charging a 12V20AH battery pack, the current value is generally 3A, and the limited voltage value is 14.8V. Constant voltage and limited current: When the current drops to the jump current value, proceed to the next step. The constant voltage is 14.8V with a limited current of 3A until the current drops to 0.55A and the light jumps. Trickle float charging: Also known as maintenance charging, the float charging voltage is 13.8V with a limited current of 0.55A. This stage generally lasts for 2~3 hours before power is cut off.
I've been driving a Geely Boyue for three years, and the battery is a 12V 60Ah one. The direct charging time depends on the specific situation. If you use a 15A charger to charge a completely dead battery, it will take about 6 hours; if it's a 10A charger, it will take more than 8 hours. Be careful not to use a charger with too low power—if the current is below 5A, it might take a whole day to fully charge. I recommend keeping the hood open for ventilation while charging and unplugging the charger as soon as the green light turns on. Once, it took me 10 hours to fully charge because the battery was old and its internal resistance had increased. The safest option is to buy a smart charger with an automatic stop function.
I'm in the habit of regularly checking my car's battery. The Geely Boyue's battery capacity is generally 60 ampere-hours. The charging duration depends on several key factors: if the battery is only half-charged, using a 10A charger for about 5 hours should suffice; if it's completely dead, it may require 10-12 hours of uninterrupted charging. The choice of charger is crucial—ordinary household chargers have low power and efficiency, while professional repair chargers with pulse function can shorten charging time by 2-3 hours. Remember to clean the battery terminals before connecting to avoid poor contact affecting efficiency.
As someone who often helps friends with car repairs, special attention must be paid to safety when charging the battery of SUVs like the Boyue. The charging current for regular household use should be controlled between 6-10A, and it needs at least 8 hours of charging when completely depleted. In fact, the most reliable method is to drive for more than half an hour to charge via the alternator, which is twice as fast as external charging. If external charging is necessary, first check the battery fluid level and add distilled water if the electrolyte is insufficient. During charging, check the battery temperature every 2 hours by touching it; stop charging if it gets hot to avoid battery swelling.
