To maximise the performance of the Lithium Ion battery provided with your Y70 fusion splicer, we recommend that the you charge the battery for 18 hours before using for the first time.

Thereafter, the battery will take 6 to 8 hours to recharge. An LED indicates whether the battery is charging or has completed its charge. When charging, the indicator will be red, and when fully charged, the indicator will change to green.
At the end of a day of installation, we recommend you charge the battery overnight. This will not damage the battery.
