Using standard batteries where lithium is recommended is ok except they will run down faster. If you don't mind constant recharging you will be good to go. The cost effective ideals with lithium outweigh the aggrevation of constant recharge of batteries for me. I save all my old batteries and dispose of them properly.
The copper ions (atoms?) then in turn can stick on to the anode during charging by chemical reduction and cause dendrites. The dendrites might cause a short circuit inside the battery. So basically discharging too much is as bad as charging too much. But the dendrites caused by overcharging is formed out of lithium.
The optimum charging level is around 40%, higher and lower values stress the battery more and would limit the battery's lifetime. A full-discharge is very harmful for Lithium based cells, it is best to avoid that. Lithium based cells suffer very little from self discharge so that 40% charge can be kept for a long time in storage.
\$\begingroup\$ One problem with at least some types of primary-cell chemistry (and to a lesser extent with some rechargeable ones) is that draining the cell will erode away one of the electrodes; forcing current into the cell will deposit material back onto the electrode, but not necessarily in the same place as that from which it was eroded. \$\endgroup\$
As for the Li-Ion charger 3.7/4.2V seller tells that these can't be used too on the product Q&A. They suggest to use only their branded charger which is included with a pack of 4. This might be true due to the DC-DC circuit inside those cells. But can't tell for sure without seeing it's schematics which isn't available. \$\endgroup\$ –
About non-rechargeable lithium batteries, is a matter of chemistry: the Energizer you posted are Li-FeS2 with a voltage of 1.8 V (1.5 V under load). Reference: Energizer Ultimate Lithium AAA (L92) The rechargeable version of Kentli is the well-known 3.7 V Li-Po version with an internal circuit.
2. You should never charge one type of a battery with a charger designed for another type, because that could be truly dangerous. The reason behind is that NiMh and lithium batteries have different chemistries, different cell voltages (1.2 V for NiMh and 3.7 V for lithium), so they require different charging methods/algorithms.
Lithium-ion batteries age That is true but also depends everything I mention above and also how you treat the battery. For example in some military applications Li-Ion cells are charged not up to 4.1 - 4.2 V (like in many consumer products) but to 3.8 V or less.
18. Until the last years, my knowledge was that the rechargeable analogue of the 1.5 V batteries have only 1.2 V. This greatly decreased their usability (many devices did not work well with 1.2 V). The cause of this lower voltage was chemical and it was considered a hard limit until some years ago.
Batteries were cycled to 80% SoC using a petrol generator and a battery analyzer, then back down to 25%. No measurable differences from year 1. No news is great news :) In spite of trouble-free experience, I must stress that nothing lasts forever. Even perfectly good batteries may degrade internally just from "shelf life" even at a mostly ...
