When the battery capacity is large, its internal resistance is small and the error is small for the values measured by different models of voltmeter.

当电池容量大时，其内电阻小，不同类型电压表测得开路电压值的误差就小。

However, if you feel the HIGH error is due to a false detection, try charging the battery first in another charger, or drain the battery first using the DISCHARGE mode on the MH-C9000.

然而，如果你认为此信息是错误的。可以尝试先用其他充电器对电池进行充电，或者先使用MH - C9000充电器的DISCHARGE模式把电池放干。
