Hi

I need some advice from you on replacing battery for Venue 7840.

Is the display assembly attached to the main body with sticky glue? Is it helpful to heat up the edges of the display assembly with a dryer or heat gun before removing it?

Thanks in advance

Yes it is attached with glue, removing the screen as described will likely result in a wrecked screen unless you're a magician. Also, the battery seems to be glued to the back of the device, making removal challenging. And by that I mean almost impossible without destroying it.

Hi,

Assuming you are already using replacement battery, please share the replacement battery yo used. Also, how is the performance of current battery.

And also let us know if you have any advice or suggestion for battery and if it is worth to replace battery.

Can anyone who has actually performed this replacement discuss how difficult or easy it actually was? Did you use only the tools listed or was the heat gun necessary/useful? Does the tablet with a replacement battery accept a full charge and fully discharge before shutting down? Does the referenced glue that Alex mentioned actually make this replacement as unlikely to be successful as indicated. I ordered 2 new batteries from Chinese vendor via Ebay. They both arrived with comprehensive tool kits to execute the replacement including suction cups for the screen. I have a heat gun and will most likely do this in the next 2 weeks on 2 Venue 7840’s. I’ll re-post with results.
