Advice for a new battery

[xjay]

Hi all
I'm new to this forum and italian (if i write badly endure me)
I'v bought some time ago a mp4, nano like, (you can watch it very well here Guida melody ) and because of the battery that lasts with every setting low, from contrast to turn off monitor, 3hs (and only going to&from university with train i spent 3 3and1/2) i wanted to change battery with one more and more over the 180mah standard one (even modifying the cover to plug in the new one).
My first intention were to buy something like 2000 mah or even more (for example this one Ebay )
but i've read a lot of posts here telling me that maybe it doesn't charge well or i've to put particoular attention on recharging by electric current (expecially this mympx post ).
After that i would like to ask you if there was a tradeoff mah against power recharging time (if the 180 mah takes 1 hs i fastly think 1800 could take up to 10 ) and comfort you tested and by the way if it was possible to use a 2000mah (if it charges and charges well) in my mp4 without damaging something.
tnx for the help :wink:

A Rockchip? In a ping guo er dai? That' very rare.

Yes, if you put in a bigger battery it will take longer to charge. But as long as the voltage is the same, it should not be a problem.
