Battery Handling 2 Additional Features

E6000C Mini-OTDR User’s Guide, E0302

Best performance • For the best battery performance and accuracy of the

fuel gauge (showing percentage use of the battery),

completely discharge the battery, then make a complete

fast charge cycle (non-operating), and completely

discharge the battery again.

NOTE You must ensure that the charging cycle is not interrupted

by a battery discharge, and that the discharge cycle is not

interrupted by battery charging.

Battery temperature • It is best if you charge the battery at a limited and

controlled temperature

(10°C to 35°C, 50°F to 95°F).

• It is normal for the battery to become warm during

charging or after use.

• When completely charged, the battery will discharge

down to 80% before a new charging cycle is activated.

Battery Storage

• Remove your battery from the Mini-OTDR when not in

use. Store at room temperature (59

°F to 86°F, 15°C to

°C), and in a dry place for optimal performance.

• A charged battery will gradually lose its charge if left in

storage. It is therefore better if you top-off the charge

before use.

• It is good practise to recharge the battery every 2-3

months during storage.

Battery safety

Your battery has passed a UL-listed safety test. For the

best results, wipe the battery with a soft dry cloth if it

becomes dirty.

Do not disassemble or attempt to open the battery under

any circumstances.
