What are the specs for a replacement battery for my Literati?

Hi @lkvee

With the battery in its normal position in the tablet, measure how much space there is available on either side. It looks like there's space available in the length

I've found a battery size that might fit.

Looking for a 4060120 3.7V LiPo battery gave results as shown in the link.

The way to interpret the code on a battery is as follows:

4060120 = 4.0mm height¹ x 60mm width x 120mm length.

¹The decimal point is not shown in the height measurement in the dimension specifications printed on a battery

If there is space to accommodate the width i.e. 60mm then ensure that you get a battery with a 3 wire connection. The 3rd wire is normally used for temperature monitoring of the battery, especially when charging and if you get a battery with only a 2 wire connection i.e. red and black, you may have problems with it charging correctly and also getting too hot when it is being charged.

You can get a battery with a higher milliAmpere (mAH) rating as this means that the battery will last longer before it needs recharging, but it also means that it will take longer to fully charge, but ensure that it has the 3.7V voltage rating and not higher (or lower).
