View Full Version : Am I correct in thinking that...

...Lithium Ion batteries have no memory, and hence can be charged whenever, despite the fact that they are not fully discharged, with little or no negative effect on the battery life? Just want to check, as replacement packs waste money I should be saving towards a couple of conversion lenses. ;)

Since Lithium-Ion battery packs are used in almost all mobile devices such as phones, PDA's, and even laptop computers, I am pretty sure that is correct.

That is correct, you don't have to worry about the memory effect with Li-Ion cells.

For some types of Mobile phone Lithium Ion batteries, it is actually better for the battery life if you do not fully discharge them before recharging them. Instead you would charge it while it still has a little charge left.

Whether that applies to batteries for cameras, you may want to find out.

Yes, you are correct in thinking that lithium ion batteries have little to no memory.

I swear I replied to this ages ago...never mind, thanks all. :)

Every now and then, they do need to be run down to device cutoff and then recharged to refresh the battery meter circuits in the battery. The battery doesn't have memory but the circuitry built into Lion batteries will take a bit of a memory and just need to be refreshed occassionally.
