Regular or slice 9-cell battery?

Hello!
I'm new to this forum.

I have a T410i 2518 with a 6-cell battery that I have to recharge 1-2 times per day. It's getting tiresome so I want more power.

The 9-cell comes in two versions, the regular spare battery 55++ and the bigger and heavier slice 27++. Wich is the better to get? I mostly use my laptop at home in my sofa. Dont like to use it plugged in on AC.

The 27++ have the advantage that it can be combined with the original battery, but can I charge both batteries at the same time with the AC adapter?

Thanks in advance,
Peter

 

the slice battery slightly raises the bottom of the battery, giving a natural slope to the keyboard of the laptop (as the laptop is slightly raised at the back), which is more comfortable to type on.

If you need maximum battery time, then the slice battery is the best option, as it still allows you to use the 6 cells battery you have.

 

Yeah more comfortable typing is always welcome.

The slice seems like the better option yes, but do I need a separate charger or can I just charge both batteries installed like usual with the 90W adapter?

 

they charge through one charger, not sure whether they charge at the same times or in sequence (one starts when the other finishes charging).

You won't need to use a separate charger.

 

Ok that's great! A slice it is then

Thanks a lot!
