Initial charge was overnight. I left it on to completey discharge it and it took about 8 hrs or so.

Re read the manual . There are times you have to put the manual switch on for a few days to charge it to FULL capacity ....especially id you have the second battery attached to it. It always runs down slowly over a coule of months and will not charge if it is not down to @ 75% -80%. Then the manual setting will charge it to full. It may have come to you almost fully charged. Hope that helps. One more thing ..write or call My E they are very helpful w/ any issues.

a fully dead battery might have other problems, like shorted cells, or something else that might affect it's ability take a full charge. But as far as the battery charger goes it should charge overnight, it's best i've ever had

Be sure to use the original charger, ley it charge over night ando rehén try again, for one reason if You dont charge it with this charger ocurrs that problem. Hope this helps You

It sounds like you're using the wrong battery. When I recharge my battery I sometimes leave it charging for more than a day, and I've never had any trouble.

I'm not entirely sure as I normally put it on overnight. I'll try and see next time it requires a full charge. I suspect it takes a few hours though.

Make sure the "on" switch is OFF when you plug it in to charge it, the red light will come ON if its charging. It wont charge if the switch is still "on", like I've done a couple times when I let it run out of power while I was watching it. I forgot to turn it "Off" and it didnt charge when I plugged it in to charge. If that doesnt work, then maybe your battery is defective and you could send it back if its under warrenty still.

Mine was good for a couple of hours. It is best if you stick with an actual Lenvo battery. Those last4-7 hours depending on usage.

Sounds like you have another problem. New battery was fully charged 4-6 hours

Probably a bad battery. Ours can be off the charger for days and still have a power, not being used that whole time. As in, I had it for a nap time while I was outside and turn it off after nap (couple hours) but don't plug it in, it will still have charge a few days later. It has also lasted over night (audio only) not being plugged in.

Hey there, I left mine plugged in this winter and it completely drained it and it wouldn't hold a charge. The note on the charger clearly says not to keep it plugged in at cold temperatures. So totally my fault. I went to Batteries Express and had it replaced(well there are actually two inside of it), just shy of 120 bucks, but cheaper than buying a whole new unit.

Hi Norma. I never had a problem with it if I charged overnight. Its possible to get a couple of days between charges if its not on all the time like at work, etc. I work in call center so its off for 8hrs on those days. I was happy with it till I lost it. Like all most of the others. :-) Happy Halloween.

I got a similar unit recently and when I plugged it in, it too showed 100% charged. However, I unplugged the charger and checked the battery voltage which instantly dropped to under 6V. So that told me that the battery wasn't accepting a charge and the "100%" reading was coming from the charger just while plugged in. So I left it plugged in and after an hour it did start accepting a charge and the reading dropped to 60% or such. So it does take at least 12 hours, after that if it starts displaying 100% it probably is charged.

This may be worth a try, but leave the laptop turned off, disable any charge thresholds you may have set up on the Thinkpad, and plug it in overnight. Both batteries should charge up to 100%. If that fails, remove the main battery and leave only the slice battery in, plug it in with the laptop turned off. Bit of a bizarre problem though, afaik, the laptop drains the main battery before the secondary. Maybe it's doing it in reverse somehow, but not switching to the main battery once the secondary is drained. Once both batteries are fully charged, it should behave normally.edit: As Kirk mentioned, use the charge port on the slice, not the rear port.

Yeah that's normal. Charge it overnight. That's actually a good sign. A slow charge is better. Same with mine. 6-8 hours.

I emailed the company about this very issue. They said that was a feature on the prototype but was never programmed into the regular production models. I was told it will not turn off but that it should be fully charged in about 5-6 hours.
