Battery Use And Battery Life - Xylem YSI ProDSS User Manual

Introduction

Battery Use and Battery Life

The ProDSS uses a rechargeable lithium-ion (Li-Ion) battery pack as a power source. The battery comes pre-installed in
the ProDSS and does not need to be replaced until the battery charge capacity is deemed unacceptable by the user.
The battery is shipped at less than 50% full capacity and charging the battery is not required before first use.
Battery life depends on use, enabled parameters, LCD brightness, and GPS use. As with all lithium-ion batteries, battery
life will decline over time and use. This decay is typical and should be expected.
A new ProDSS battery is expected to last for the following durations (25 °C (77 °F), auto sampling, GPS on, keypad
backlight off):
• ProDSS instrument only - 48 hours
• ProDSS with fully loaded 4 port cable assembly and 25% LCD brightness - 20 hours
• ProDSS with fully loaded 4 port cable assembly and 100% (Default) LCD brightness - 14 hours
To increase battery life, enable manual sampling mode
sensor/s on to take a measurement and then powers down to conserve battery life. Battery life may also depend on
the battery charging practices used. For maximum battery life, keep the battery 40% to 80% charged. Also, a larger
discharge (e.g. to 50%) is better than a small discharge (e.g. to 90%) between recharges.
