Have had my YP-T8 for about 2 years and even though I charge it every night, the battery only lasts about 7 hours. Can you get a replacement internal battery or is there a special discharge sequence to "recharge" the battery or help the length of charge?
Thanks in advance
The thing is, you recharge it too much. Because when you recharge it even though it still has battery power left, it tries to recharge it as much as if the battery was depleted. So, your battery overheats, therefore allowing you 7 hours instead of 20. And yes, it is possible to switch the battery.

Depending on what you are using the watch for it will have different battery life. Using the talk feature you should get around 2 hours, on standby about 7 days, the analog watch has a seperate battery that should last 2 years and charging the watch takes 2 hours to get a full charge.
With the BT Interphone that I have (~4yrs), one unit's battery would last <1hr. I carefully cut the rubber case along the bottom mold mark to remove the circuit board. The battery is a 3.7v 600 mah lipo. These are available from a variety of hobby shop sources, but are 650mah. $7-15 ea. Very careful cutting of the rubber case and minimal heat soldering is critical in installing a new cell. I'll use 3m weatherstrip adhesive to close it up.
Otherwise a complete new 3rd generation BT set-up is about $90 online. Mine still works good though.
It is best to let it charge at least over night, longer if it hasn't been used for a while. It is also good to give them a long workout (Don't completely flatten them though) at least occaisionally. If they get regular and thorough use they will last longer, but extra weight like shopping, or lots of steepish paths will flatten them a lot faster. They are only supposed to last a couple of years, but will go longer if you look after them.
One of the most important things is to find a supplier/repairman you can trust. These are, after all your legs or mode of transport you are talking about.
sounds like that batteries need replaced-depending on the freq of your use,like i use mine 24-7 and the orm battery has a shelf life of a year,but with daily 24-7 use like me,that time is cut in half,so wheres the norm batt life for a heavy chair user is somewhere round 6months or so,im ure its the batteries though,have had that same thing happen 2ce b4
Will the old battery (that you are replacing) charge up at all? If the old battery charges but the new battery will not, then it's likely a bad replacement battery.
To rule out the possibility of a corrupted battery meter inside of windows, you may wish to leave the laptop on battery power only, until it dies. A 5% charge will usually only grant you about 20 minutes of laptop life maximum. Since you left it charging all night, you should get a few hours of life before it dies. If you get a few hours of life, the battery meter software is corrupted.
Most likely though, the replacement battery is bad.
have you let the battery go totally flat as this is recomended to do every couple of months because if you dont let the battery go totally flat this stops the battery from full recharging and will cause bad cells in the batt so i would let hte battery totally flat till it wont even light phone up then fully charge for 16 hours see if this improves the battery if not then the charger is probably over heating and cutting off so you could replace the charge hope this is some help to you
