Avoiding battery damage in charger (springs)

[Mowgli76]

My charger has those eeh springy slides to keep batteries tightly set.
Couldn't find a respectable charger without them.

How do you avoid damaging the battery wrap when inserting/removing in a charger?

Inserting a battery is easier as you can preload the slide with a finger.
But when removing a battery the spring slide eats into the battery wrap on the way up.
Would be nice to avoid any wrap damage.

Maybe put a rubber band / twine / other (non-conductive) underneath so it can be pulled and open the spring slide after charging?
Like a slingshot
Other ideas?

I've had mods year wraps, but never torn abattery wrap from a charger, I've only ever used nitecore, but there are other brands recommended around here too. More durable wraps are also a solution, as the thinner wraps that come on oem batteries aren't meant to be used as we do.

Yeah maybe it's a not an issue.
I'm just getting into 21700 batteries and charger, and just want to avoid it happening.
But I guess being a bit careful and fast helps
And maybe putting the springs in full tension for a few days will make them easier

The biggest issue with the charger design, from my perspective, is the springs wearing out. Especially with heavy repeated use.

Even for large batteries like 21700?
They are already nearly as long as the charger slot

Especially so, as the longer battery stretches the spring more than a shorter one.

I always try and release my batteries from the top first, opposite end to the spring. This means you can still keep the spring tension on the negative end of the battery as you lift it out so hopefully the spring doesnt then snag the battery.
Works for the Nitecore, Xtar and Effest chargers I have.

My last charger, the spring went. And when it did, it went all the way. No tension at all. There was no way to change any battery, big or small, in that side of the charger.

I hear you about the potential for tearing a wrap though. I use 18650s and 21700s about equally and the only difference is how well you can get a grip on them to get them out. Sometimes it’s easier to grab the bigger batteries, sometimes harder.

I just get a good grip, slide towards the negative end until the positive end is clear. I never just yank them out.

I just Don't Understand why OEM's can't make the Battery Slots about a 1/4" Longer?

Or why thy Can't have a Non-Conductive Tab on the Negative Side of the Battery Slide to act as a Pull Tab?

Or even better:
Skip the big springs and just use adjustable length with locks.
I mean: put battery in, adjust tightness and lock it

There's Probably about 3 Dozen ways that a Battery Charger can be Made Better.

Unfortunately, Most OEM's are Great at using the Same Design and then putting Bells and Whistles on it. But when it comes to True Innovation, or coming up with New Designs, many Fall Flat on their Faces.

I wish they would make the pin that the springs attach to stronger.
Have broken four on two different chargers...

But think what that would Do to the Replacement Sales market.

I don't have much problem with damage to wraps unless it's the original wraps on Samsung batteries. Samsung wraps are ultra thin. I need to use a fingernail when removing batts and the samsung wraps tear very easily at the positive side when removing from charger. Because of that, I just rewrap all Samsungs within a week or even immediately when I start a new Samsung battery.

I don't blame samsung since these are not meant to be used like we use them, they are OEM batts. But as a low wattage/low amperage vaper, I don't need to be too particular in what batteries I use so I won't be buying any more samsung batts going forward.

I never have this problem with LG or with rewrap brands. In fact, I have never had to rewrap a rewrap. Rewraps tend to have very thick and durable wraps compared to OEM batts but I understand that some vapers may not be able to use most of the rewraps on the market.

I agree that there must be a better system for securing batts in the chargers.

We also do want things as cheap as possible. Cheap + good quality often doesn't mix

I guess I'm Old School. But I would rather Pay 5 Bucks More to have something that Works Well and Lasts.

I mean, it's Not like I'm buying a Battery Charger every month.

I double wrap all my cells with a clear wrap. Even after a few years of use, I've never had a tear or nick in one of those.
