Best battery for low drain devices?
The discussion came up regarding low power wireless PC mouse being a device that could more completely discharge (i.e. use) what little charge might be left in a battery due to the low current draw. Backing up a bit, the initial idea was that a periodic discharge was thought to be helpful to the life of the battery.
Understanding Alkaline Battery Performance in High-Drain vs. Low
This characteristic is a double-edged sword: while it limits the battery''s efficiency in high-drain applications, it also prolongs the battery''s life in low-drain scenarios. When a high current is drawn, as in high-drain applications, the internal resistance causes a significant voltage drop, which in turn reduces the available power.

Is slow charging a Lithium Polymer battery any better for it?
Every lithium charger that I have seem charges on the CC-CV algorithm and terminates charge when the current in the CV stage gets to 1/10 the current of the CC stage. So if you start with a very low charge current, the charger won''t terminate charge until the current is 1/10 of that small current. The result will be a very full battery!

6 FAQs about [Low current is good for batteries]
What are the advantages of low current mode?
Advantages of Low Current Mode: Optimized Charging: Low Current Mode provides precise charging tailored to the specific power requirements of low-power devices, ensuring optimal battery health and performance.
Is slow charging a battery a good idea?
Slow charging does come with the trade-off of longer charging times. If you’re in a hurry or constantly moving, there may be better options than waiting for your battery to charge fully. Moreover, some newer devices may not support slow charging or lack the necessary compatibility for this method. How to Charge a Lithium-ion Battery? Part 4.
What is low current mode?
