charging cable long - Generation Z Gadgets
Question How long should you wait after usage before charging? For example, if I use a battery powered string-trimmer or lawn-mower and the battery has gone empty (and probably quite warm,) how long should I wait before connecting it to the charger? I guess reasons you should wait are temperature, or ongoing chemical reactions.
Understanding the Context
batteries - How long to wait between usage and charging of a lithium ... I'd throw out all the "charge-only" cables. As the other answers have indicated, charging over a cable with the data lines disconnected is slow at best, and overloads the port at worst. If you want to inhibit data communication, use a USB condom or one of its many clones that reproduce the power negotiation while blocking data.

I am constrained to the following: 3S lithium-ion battery of 2600 mAh charging at 1 A, USB-C connector with 5 V, the BMS is already included with the battery. My main question is if this solution will work and if this is the best way to handle charging given the constraints. Everything seems to check out with the Boost circuit and charger spec ... Creating a 12.6 V 3S Lithium-ion Charging Circuit from 5 V USB-C How do I calculate the approximated time for the Charging and Discharging of the battery? Is there any equation available for the purpose?

If yes, then please provide me. Charging lead-acid batteries with a power supply Lead-acid batteries can be charged manually with a commercial power supply featuring voltage regulation and current limiting. Calculate the charge voltage according to the number of cells and desired voltage limit. Charging a 12-volt battery (6 cells) at a cell voltage limit of 2.40V, for example, would require a voltage setting of 14.40V. The ... 2 Don't use a TP4056 for charging LiFePO 4 batteries; it won't stop charging until about 4.2 V has been reached and while some LiFePO 4 batteries will probably handle that without exploding, it could damage them and will shorten their cycle life (the number of times they can be charged and discharged without noticeable deterioration/capacity loss).
