The time required to fully charge any battery depends on several factors including the total capacity of the battery, the remaining capacity on the battery, the charge rate and also the charge method of the charger. For most balance charger, it will automatically adjust to a lower charge rate when approaching the upper charge voltage limit, to avoid overcharging the battery. But as a lower charge rate is used, it will then extend the time required to reach the upper voltage limit. You may choose fast charge mode if available on your charger, which will stop charging when it is approaching the upper voltage limit, but your battery may not be fully charged. |
