What's there to say, it's a replacement battery. It arrived on time, fit the device and works properly. Doesn't get much better, or less complicated than that.

It is an extra battery for the Plantronics Savi 740. It charges, it works. I get about 4 hours of continuous talk time per battery. I ordered this and the deluxe charger without realizing the deluxe charger includes a battery. Unless you want an extra battery just buy the deluxe charger - it's a better bargain.

The Plantronics Replacement Battery for the Savi 740/440 Headset is a convenient backup or replacement battery for Plantronic's Savi W440 and W740 convertible headsets. On a full charge, it provides up to 7 hours of talk time, 50 hours of standby and up to 75 days of storage time when removed from the headset.
When using the battery for the first time it must be charged for a minimum of twenty minutes. A full charge is reached after three hours. The battery charges by either docking the headset on the charge cradle included with your Savi system or by using the Deluxe USB charging cable. A Deluxe Charging Cradle can also be purchased separately allowing you to charge an extra battery and your headset simultaneously.
Installation is easy, simply place the battery on the inside of the headset and slide it into position. The battery can be switched in mid-call without getting disconnected as long as you reattach the new battery within five minutes. This provides the W740 and W440 headsets with unlimited talk time and an excellent reason to have a spare battery on hand.
