A Lithium Ion rechargeable battery pack (6608500) is available for the 940 Flow Meter
only. This is an alternative to the lead-acid and primary metallic Lithium
(non-rechargeable) battery offered as an option for the 940 Flow Meter.
The Lithium Ion rechargeable battery pack is designed to allow up to 500
charge/discharge cycles and is shipped with a charger designed specifically for this
battery pack. The Lithium Ion charger has specific plug wiring to prevent use with the
primary non-rechargeable metallic Lithium pack or the lead-acid pack.
Do not attempt to use the Lithium Ion battery pack charger with the primary
non-rechargeable metallic Lithium pack or the lead-acid pack. Do not attempt to use the
lead-acid pack charger with the Lithium Ion battery pack.
DANGER
The use of chargers other than those provided by the manufacturer for use with
these batteries is not recommended and may damage the battery or shorten battery
life.
DANGER
Il est déconseillé d'utiliser des chargeurs autres que ceux fournis par le fabricant
pour ces batteries, car ils risquent de les endommager et de réduire leur vie utile.
Maintenance
This battery pack requires no maintenance other than charging.
