What do the battery lights mean on my mouse?
Some keyboard and mouse models feature a battery light that shows the current status of the batteries. The following table describes the different lights and states.
Single long green blink
Batteries are good. This occurs when batteries are first installed or every time that the device is turned on.
Slow green blink
Device is docked in the charging station and is charging properly.
Device is docked in the charging station and does not need additional charging.
Presenter Mouse (Japanese version)
Laser pointer is on.
Device is discoverable (trying to connect to the transceiver).
Slow red blink
Batteries are low and need to be replaced.
Slow red blink
Batteries are low and need recharging.
Fast red blink
Device is docked in the charging station, but there is a charging error. Reasons for errors: The wrong type of battery is installed; the battery or batteries are missing; or the battery connection is bad. Solutions: Make sure that the correct battery or batteries are installed, and are installed correctly. If necessary, remove the batteries, wipe them with a clean cloth, and reinsert them.
Presenter Mouse (Standard version)
Laser pointer is on.
The first thing to realize is that most wireless keyboards and mice will eat regular alkaline batteries for lunch. This is where most of my clients have gone wrong. It seems they are replacing batteries in a device around every month or even more often. For an office full of wireless devices, this can add up very quickly. Plus it also seems that certain devices act inconsistently with regular alkaline batteries. If you need to purchase a non-rechargeable battery for your wireless devices, you should purchase the "advanced" or "performance" type of batteries such as the Energizer Lithium or Duracell Quantum brands. For what it's worth, the Apple devices usually come with Energizer Lithium brand batteries. However, high performance batteries are more expensive than alkaline batteries and their cost will add up over time. So I don't recommend buying these batteries except in a pinch. What I really recommend are a particular type of rechargeable battery called low-discharge Nickel Metal Hydride (NiMH). I believe many people stay away from rechargeable batteries because of misconceptions based upon past generations of rechargeable batteries. Many people perceive rechargeable batteries as expensive and prone to failure. But the worst stigma associated with rechargeable batteries are that they don't hold their charge and never seem to be ready when they are needed. The reality is that today's new generation of low-discharge NiHM rechargeable batteries have resolved many of the issues that previous batteries suffered from. Low-discharge NiMH batteries hold their power on the order of months or years after charging. Unlike previous iterations of rechargeable batteries that lost their charge quickly, you can charge these batteries any time and they will be ready for use when you need them.
Rechargeable batteries do expire after a while either get new ones or get a battery tester to see how much life they have left. under normal circumstances a new set of batteries last me about two weeks before i have to recharge them and my computer stays on 24/7 including the mouse with at least 5 or more hours of use per day.
BATTERY INSTALLATION AND INFORMATION Your wireless headphone unit requires two rechargeable AAA batteries. Rechargeable batteries are uncharged when you purchase them. Before you can use the wireless headphones, the batteries must be charged for 16 hours. Follow these steps to install and charge the batteries. Installing the Rechargeable Batteries Take care to follow these steps to correctly install the batteries. 1. On the right headphone, locate the battery compartment (1). Use the finger depression on the compartment to turn the battery compartment cover counterclockwise to remove the cover. 2. Insert two AAA rechargeable batteries, carefully following the markings inside to ensure the batteries are inserted properly, with the + and - ends in the correct positions. 3. Replace the battery compartment cover. Charging the Rechargeable Batteries To recharge the headset unit, follow the directions below. Note: The cradle/transmitter on the WHP141 is not a recharging cradle, although you may place the headset in the cradle during recharging. Follow these steps to recharge the NiMH rechargeable batteries. 1. Make sure the ON/OFF switch (2), located on the right headphone, is in the OFF position. 2. Connect the AC/DC main power adapter to the DC IN power supply socket (11), located on the back of the cradle/transmitter. 3. Plug the adapter into an electrical outlet. 4. Connect the charging cable (10), located on the back of the cradle/transmitter to the recharging input (3), located on the right headphone. The headphones can either be placed in the cradle/transmitter or placed next to the unit. If the headphones are connected correctly, the charging LED indicator light on the cradle/transmitter (8) illuminate.
