i can't get it, how can we got 19-hour of battery life in E4300 for example ?!!

 

You use the biggest internal battery plus the battery slice which goes on the bottom. You might also need to have a P series or lower power CPU and an SSD.

People with the E6400 get up to 9 hours using the normal 9 cell battery so 19 hours if using the slice in addition should not be impossible.

batt slice + ssd
proven in our office

 

cool, but i think that would happen with the E6400 only.
i mean it can't happen with the E4300 because it have the 6-cell as a maximum available battery, right ?

beside please guys, what do u think about the maximum battery life for E4300 machine with the 6-cell primary battery and the 6-cell battery slice ??

 

e4300 has a batttery slice also

 

I'd say a typical E4300 probably doesn't draw much less power than an E6400 optimized for long battery life. Assuming you can get a bit more than an hour per cell on the E4300 (a lower power E6400 typically manages a bit less than an hour per cell), I'd say you'd be looking at 12 to 14 hours with both batteries?

 

They claimed 19-hours for the E6400 with the 9-cell battery (85 Wh) and the battery slice (84 Wh), which is achievable under very light usage.

The E4300 uses different batteries as I showed in the other thread. The highest capacity battery for it is 60 Wh (6-cell one) and the battery slice is 48 Wh, so I would say 10-12 hours under very light usage at best.

 

l know that,
but hay i wonder about how the E4300 will looks like with it's 6-cell battery slice ?! .. will it be kind of ugly like the E6400 with it's battery slice ??.. anybody have pics for the E4300 with it's 6-cell battery slice please ?

I think I also read that the claim was made while using an ssd.
