Why do my e-Cig mods use NiMH rechargable batteries? I’ve been asked why I use regular NiMH batteries in my e-cig mods like the Puck instead of Lithium ion like the commercial e-cigs use. I have many reasons which I will outline below and you will then see why I feel they are ther best choice for my mods.
I have a few rules I follow when coming up with an e-cig mod. The first and foremost is built around powering the mod. This means batteries. Most mods and commercial e-cigs use lithium ion batteries. Lion batteries are small and lightweight and can supply more voltage for a smaller package. So why don’t I use them?
The reason commercial e-cig manufacturers use them is they needed a smaller battery that was about the same size as a real cigarette so an e-cig can mimic a real cigarette in size and shape. The problem is those smaller batteries still cannot produce the current of the larger batteries. That means you usually only get about 4 hours or less out of a commercial e-cig battery before it needs to be recharged. Also, lithium ion batteries need special charging and discharging protection circuitry to make sure they don’t explode from over charging or over discharging (use). You can get larger lithium ion batteries but you have to order them and you have to have special chargers to charge them. The batteries you use must be protected batteries which means each battery has the circuitry butil into them to protect them from over charge or over discharge.
All that being said, one of my rules for any mod I come up with is you should be able to get the batteries from any local store. Currently, the only readily available rechargable batteries you can get at any store is NiMH batteries. You can even get them at your local grocery store. That way, if your battery dies, you don’t have to wait on an order to come in, you just run to the local store and pick some up.
NiMH rechargable batteries do not have the charging and discharging issues of lithium ion so no protection circuitry is needed. The chargers handle the charging restrictions and there is no discharge issues like lithium ion has. MiMH batteries have been the workhorse of the rechargable battery market for years.
Many people think NiMH has the old ni-cad memory effect that happens of you don’t discharge them all the way every time. This is not true and you do not have to completely discharge your batteries. NiMH technology has eleminated that. The NiMH charge lever output stays pretty much constant until the very end of the charge life, only dropping off a few tenths of a volt during the use of the batteries.
The only disadvantage to using NiMH batteries is, you have to use 4 batteries instead of one to get more than 3.7 volts. But what I have found (and every one else that uses a Puck agrees) is that running around 4.8 volts is better. So in reality having the to use multiple NiMH’s batteries benefits (as in the Puck) are much greater than having to just deal with 4 batteries instead of one.
The real benefit is being able to get your batteries from just about anywhere at any time. You can also get 15 minute chargers for NiMHs that will have you batteries freshly charged in 15 minutes instead of waiting 2 to 4 hours for your lithium ion e-cig battery to charge.
I’ve been using nothing but NiMH rechargable batteries in all of my e-cig mods for 2+ years now and will use nothing else.
