Taking care of Li-Ion batteries

[GeoffW1]

Hi,

Here's a look at taking care of Li-Ion batteries. Some of it may seem a bit over the top, but with non-replaceable cases (pun) like Nexus tablets, it may be worthwhile. It is a safe link:

Pretty well the whole page of text is greyed out except for a couple of questions??
Now working ok..go figure....

Thanks for posting, Geoff. Very useful info.

Especially with non-replaceable (or non-removable) batteries it is over the top. Tips 2 and 3 simply don't apply, you cannot overcharge or deep discharge a non-removable battery in a smartphone, tablet, etc.

Actually most of it is completely off base. These would apply for the remote control plane crowd or the electronics crowd who use raw lithium cells, but every commercial device on the market includes cricuitry either in the battery itself (notice how there's more than just a +ve and -ve terminal on these cells) or in the device itself.

To put it simply it's not possible on a laptop, tablet, mobile phone, cordless battery, wireless speaker etc. to over voltage the battery, over charge the battery, over discharge the battery, or charge the battery to fast. All of these actions are regulated by the device itself and it makes no difference whether your phone is plugged into a cheap USB charger or a nuclear power plant, the phone does the charging, and the phone decides how to charge and will stop charging when it's full.

The only thing in that article worth the read is the bit about temperature. Lithium cells are very sensitive to temperature. But unless you like me use raw lithium cells and charge them with a variable charger which allows you to set the charge curve and rate then not only is none of the rest of that article relevant, but it's also completely out of your control.
