Battery Charging Question

[tony46113]

Why don't battery chargers stop charging when the battery has reached a full charge? As much as the "Don't Overcharge" and "Don't Charge Unattended" topic comes up, why can't a charger be made that just stops charging when the charge is complete?

I can't remember for certain, but I thought I used to have an old AA Ni-Cad charger that did that.

There are any number of those chargers already on the market. Not everyone buys one.

Regardless, even the best of chargers can have failures or be subject to accidents. Given the kind of batteries we use in vaping, paying proper respect to them and erring on the side of caution has never caused harm. Failures or accidents, well..................

I've used the same charger for the last 3-4 years. I can't ven remember when I got it. It's an XTar VP1. It has 3 charging levels, digital readout of voltage of each slot while charging, and stops charging when the batteries reach full charge.

Li-ion battery chargers do stop at full charge but you must be diligent in checking to insure they are working properly.
Batteries are in their most vulnerable state when charging, if your not there you can't react should something happen.

A good charger WILL stop and switch to trickle charge mode. It'll monitor the batteries to prevent overcharging.

Just get some silicon or other cases/sleeves and take them out after a while and/or don't use the batteries for at least an hour for them to stabilize and cool. It's better for them.
