How do i recharge the battery - Eclipse Fit Clip Plus 8GB* MP3 Player

It does take rechargeable batteries. Remove the back and change batteries for Ni-cad or similar rechargeable batteries. Trying to recharge normal batteries is dangerous. Any rechargeable make of battery will normally work and they recharge when phone is in cradle

You can get rechargeable CR5 battery and you will need a battery charger as well.

On the Top on the Mouse u can see the Battery u need to Remove the old Battery's and Replace with New battery see that you use Rechargeable battery because ordinary battery life spam is very less and u need to change the batterys for every 1 month so if u use the rechargeable battery then u need not change battery for 1 month at least for 5 or 6 months the rechargeable battery work and u can keep and spare rechargeable battery when every needed and try to purchase a Sony Rechargeable batterys

battery's life is governed on the number of recharges. so it is always recommended to recharge a battery only when it has been discharged completely. generally a blinking battery symbol denotes that the battery needs recharging.

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.

did u try connecting it to your computer like i do mine

Did you go online and look up this troubleshooting tip from HP?  Did you make sure the batteries are rechargeable and in the correct orientation ( + and - )? Here is the results from looking up the error code M627-435 at the HP website:
Solution

1. Ensure that the batteries are rechargeable. If the batteries are not rechargeable, replace them with rechargeable batteries.
2. If the batteries are rechargeable, take them out and check for obvious physical damage. If the batteries are damaged, replace the batteries with rechargeable batteries in good physical condition.
3. If the batteries are in good condition, charge the batteries using the external charger that shipped with the camera before using them in the camera for the first time.
4. If you have tried each of the steps above and the status message still displays when you try to charge the batteries, replace the batteries.

Cause The Batteries cannot be charged status message is usually caused by one of the following:

• When first connected to an optional HP AC power adapter or placed on an optional dock, the camera performs a test to determine if the batteries are rechargeable. If the test determines that the batteries are non-rechargeable, an status message displays in the LCD.
• If the battery charge falls below 1.1 volts, the camera cannot detect that the batteries are rechargeable. The camera does not charge batteries below a 1.1-volt threshold to prevent charging non-rechargeable batteries. Rechargeable batteries discharged below 1.1 volts can be charged in an external charger.
  Apparently, your batteries are either seriously discharged where you need to use an external AC charger to recharge the batteries or their damagaed and need replacing. Hope this helps.

Not all cameras can charge batteries. CAUTION: Rechargeable batteries must never be used in the HP Photosmart 210 and 215 series digital cameras. The overload protection and control circuits are not designed to handle the kind of power intensity delivered by rechargeable batteries. If the camera is a model that does charge batteries, ensure the batteries are rechargeable: The only acceptable rechargeable batteries for HP Photosmart cameras are NiMH cells. Neither lithium nor alkaline cells are rechargeable, and they will not be charged in the camera. The camera must detect the type and condition of the batteries The camera will only charge batteries when it detects the batteries are rechargeable and in good condition. New rechargeable batteries, and/or batteries than have been unused for a long time will not be recognized as good batteries. If the camera fails to charge NiMH batteries, charge them in an external charger once, then use them in the camera. If this does not correct the problem, the cells are old and/or damaged and new cells must be purchased.

AA batteries are available in four basic varieties: Alkaline Nickel-Metal Hydride (NiMH) Nickel-Cadmium (NiCad) Photo Lithium (Li-FeS2) Alkaline and photo lithium are non-rechargeable, while NiMH and NiCad are rechargeable. Each has advantages and disadvantages. Non-Rechargeable vs. Rechargeable: Rechargeable batteries are desirable from an environmental standpoint because they are reusable. Self-discharge refers to the fact that batteries lose energy when unused and even when not in a camera or other device. Rechargeable batteries tend to have relatively high self-discharge rates, approximately 1-2% per day for nickel-based batteries. Non-rechargeable batteries generally have very long shelf lives and extremely slow self-discharge rates. This makes non-rechargeable batteries a better choice for infrequent usage. Non-rechargeable batteries are available fully charged in stores all over the world, which makes them a convenient choice for travelers or customers who have dead rechargeable batteries and no time to recharge. Photo Lithium Batteries (Li-FeS2) (non-rechargeable): Photo lithium batteries will yield the longest battery life of any AA battery, surpassing NiMH by 50-100% and surpassing alkaline by 100-500%, depending on the load. While they are more expensive than alkaline batteries, their additional energy capacity makes the cost the same or less per shot than alkaline batteries. Nickel-Metal Hydride Batteries (NiMH) (rechargeable): NiMH batteries are the lowest cost overall solution for users that take a lot of pictures (more than the equivalent of a roll of film per month) or use a lot of high-power features. The largest disadvantage to NiMH batteries is their fast self-discharge rate of 1-2% per day whether the batteries are in a camera or not. NOTE: NiMH batteries need to be completely charged and discharged a few times when new to achieve their full capacity. Rechargeable batteries will eventually fail. If you have been getting acceptable battery life and then see a decrease in life, either quickly or slowly over time, a worn-out battery may be the cause. Storing or charging the batteries in high temperature conditions will accelerate this potential failure. Alkaline Batteries (non-rechargeable): Although the cheapest and easiest to find, alkaline batteries yield the worst performance of all the chemistries in a digital camera. They lose capacity at high power drains and at low temperatures. Skiers and other winter outdoor enthusiasts may find them unsatisfactory. Alkaline batteries are frequently available in two types: High drain (ultra, titanium, maximum etc.) Regular The high drain versions are a premium product designed to operate better under heavy loads than the standard product. However, there is a trend of major brands to increase the performance of their standard battery to b
