Can You Overcharge A Battery?

[chief druid]

Before I get slammed...............

i can feel it coming .....lol

i tend to leave them on charge a lot overnight and while i'm at work .. i worry a bit but pretty sure janty are on the protection circuit ball ... i have no taken to leaving the charger on a non flammable surface when i'm not around ... at least its a step in the right direction waaaa

This is my opinion only: I think all the "danger Will Robinson" stuff surrounding batteries in chargers is way overblown. Before I get slammed................yes, I am sure there have cases of an accident, but so have there been accidents with a toaster or microwave starting a fire as well, and I sure don't unplug every appliance in my house every night. I just have some really good and loud smoke detectors...........

My mother left a crock pot going while at work, our kitchen was totaled before the fire department was called by a neighbor...so it CAN happen. Be that as it may I leave my batteries to charge overnight and while I'm gone. I use a surge strip. Not going to unplug all my stuff either.


My smoke /co detectors talk to me (not just the voices in my head) haha

There's a slight risk of fire, yes.

There's a higher risk of damaging the battery if the cut-off in the charger fails, though. LI batteries are not supposed to be kept charging after they're full because it reduces their service life and charge capacity (from what I've read).

Sun's right. Get a timer switch and have it shut the charger(s) off for you.

My guess is that a battery left screwed into an unplugged charger will drain the battery, which would defeat the purpose. I can't speak to the chargers that our e-cigs come with, but most Li-ion chargers turn themselves on/off based on the battery voltage. I routinely leave a battery in the charger for 12-48 hours.

A few months ago I bought my Npro. I new nothing about charging
for 8 hours. I think I charged all 6 batts for about 2 hours each.
Those 6 are still going strong to this day. I never bothered to count how many hours they are good for, but they have to be at least 4 or more hours per charge. I puff at my office desk all day. When they start to weaken I fire another and put the dead one on the charger. I do clean
the threads on it quite regular. I just got in 1 of 2 shipments of Joye 510's
with manual batts. I ordered 7 batts and 7 atomizers with each of the
orders. I understand you are supposed to charge 8 hours, smoke for 20 min and then charge for another hour. I will do this as advised. I hear battery charge stays good for only a few hours. I will order a PCC
charger for good measure. Also ordered a pass thru for the office.

a proper lithium ion charging system should switch the charge of when the cell voltage reaches about 4.2 volts.. at this point nothing more goes into the battery..

the charge protection can be in the charger or in the case of something like a laptop or cell phone built into the device itself..

the stuff about the initial 12 hour charge before use is rubbish.. people that write manuals know nothing about the technical aspects of what they are writing.. and in the case of some e cigs nether do the people that sell them..

Now is that a manual from tha manufacturer? Or just from a retailer that saw a post somewhere and decided to add that to their own "users manual"? Just curious

I was surprised when my first kit arrived. I thought the manual would be something from the manufacturer (similar to buying a Sony TV), but was shocked that it was just a simple 1 page document that the retailer made.

Does anyone have a MANUFACTURERS document that states it should have an initial 8 hour charge?

Mini Electronic Cigarette(DSE901) Manufacturers manual - several pages thick, states on the 4th page: Attention: Please allow the battery to charge for 8 hours during its first charge cycle in order to full activate the batteries energy and ensure the best possible performance throughout the batteries life.

This is on the page that illustrates the component structure of the battery components.

How to prolong lithium-based batteries

"A lithium-ion battery provides 300-500 discharge/charge cycles. The battery prefers a partial rather than a full discharge. Frequent full discharges should be avoided when possible. Instead, charge the battery more often or use a larger battery. There is no concern of memory when applying unscheduled charges."

good info there. that is what I was told with my ipod too. recharge it whevner possible even if it is not fully discharged. cell phone batteries are not the same...I think.

Okay, I've read through this thread and if this question was answered, I didn't see it:

If I have a FULLY charged manual battery for my 510, how long will that charge hold if the battery is never used? For example, if I fully charge a battery on Monday, then take it off the charger and store it in a box, will it still be fully charged on Thursday? How about two weeks later?

Fresca if no one answers that for you, I'll take on the experiment and find out.

When they need charged before you store them, only charge them apx. 20-30 minutes (apx. 40%). They will hold that charge safely for an indefinite period. When you wake them up from storage, just put them back on the charger til the light turns green.

It shouldn't over charge......"shouldn't"
