Backup battery dies before main battery?

[Guest mmbecks7]

Hi

For the past few days I have observed that the backup battery dies before the main battery. It gives me a warning that I should charge it. I find this quite confusing! It has not happened before and am not sure why its happening...I thought the backup battery only starts draining after the main battery dies (keeps ur contacts etc... intact)

Any clues as to why this might be happening?

Thanks

Thats an odd one, cos I thought the backup battery didnt kick in until the main battery was running out.

Mmmm I dont know anymore than that, someone who is more knowledgeable will prob tell you more.

Methinks the battery is either knackered or has come loose. If you look at this post it's visible under the yellow sticker in the 5th picture.

Easy enough to replace. What warranty do you have remaining? It should not start discharging until the main battery is flat - it's there to keep your data alive in the absence of persistant storage.
