Histogram of maximum battery temperature
The distribution of maximum battery temperature is dis-
played in the histogram. If the battery is frequently used
without a rise in its temperature, the columns near the
"L" side will increase. If the battery is frequently used
with a rise in its temperature, for example, the overheat
protection is activated so often, the columns near the
"H" side will increase.

TROUBLESHOOTING

Histogram of maximum current discharge
The maximum current discharge is displayed in the
histogram. If the battery is frequently used for a low-
load operation, such as lighting a flashlight, the columns
near the "L" side will increase. If the battery is frequently
used for a high-load operation, such as operating a
grinder, the columns near the "H" side will increase.
