Married....how important?

[tommyboy01]

I understand the practical reasoning for marrying batteries in mods, but how important is it really?
Life of the battery, even wearing of the married cells... I get it.
In a regulated mod, what is the worst effects of using batteries that aren't married?
Is catastrophic battery failure possible?
Any and all feedback is appreciated

I can see a chance of venting ....
In an extreme mismatch, the mod will still fire, it's taking the cumulative average of the batterys power. So a battery that's way below normal operating specs is being used. Further, without limiting circuitry, the good batterys will charge the weak one in an unregulated method .... Applying a hi amperage to the weak battery.

All speculation of course, but not worth the chance of using unmarried & going kaboom

Good question though, wondered myself!

Zero.
Battery "marriage" is pure unadulterated hogwash.

Use any 2 batteries of the same type and roughly the same age/cycles.

Refreshing to hear! I kind of had a feeling that it couldn't be of too much significance.

I never married any of my batteries, it is important to keep a dialog of how many cycles they have done though. If your only using half of the battery capacity and charge it it will live longer then a cell that discharged completely and recharged...Im not sure on how much it matters but this is why people marry them, to keep them consistent.

As the others have said, it's more a "rule for dummies" type thing, which many of the so called rules for vaping are. They're made to simplify the whole thing so that those not willing to learn the full reason have at least a guideline to follow. If you don't use 2 similar batteries (similar age/usage and the same type, IE both 25rs) then you'll have inconsistent discharging which is bad, but if they're similar you won't have any issues. Say you have a single battery mod, feel free to use one of the batteries from your dual batter mod, just rotate which one you use each time you use the single battery to even out the usage.

Take the time to learn why these "rules" are in place and you'll find you can break many of them, just don't break them until you understand all the information they're simplifying. In this case it's simply wanting to balance out the way the batteries discharge so you don't end up with one battery at 3.5v and the other at 3.9v because that will cause problems.

In order to add to @raymo2u's statement. It's mainly about discharge/charge cycles. Every time a battery is discharged/charged, the internal resistance increases. Therefore, if you use an "old" battery and a new battery, the new battery suffers, lowering the overall life of the new battery, due to the new battery being discharged quicker. It might even result in over discharging the new battery, before your mod's low battery kicks in. Again, also not good for the new battery's life. Therefore, you want to use batteries, that have been discharged/charged the same number of times, in order to avoid aforementioned issues.

Marriage is not a requirement, but I do recommend at least a civil union. It's pretty important to keep the wear even. If you don't, you can get in a condition where the oldest and weakest battery is carrying the bulk of the load, potentially stressing it beyond its capacity, with results ranging from bad to catastrophic. My thinking on it is batteries are cheaper than mods and a lot cheaper than surgery.
