3BP - Size 312 Hearing Aid Battery Case (Blue, Large/8)
Quick take
The 3BP size 312 hearing aid battery case is a slim, 3D-printed pocket container that stores batteries in separate compartments and closes with a slide mechanism. It is a practical upgrade for anyone tired of wrestling with tamper-resistant battery packs and who wants batteries protected and ready to grab.
Just note it is made for size 312 batteries and batteries are not included, so you will still need to purchase your cells separately.
Pros and cons
Pros
- Compact, pocket-friendly slim design for taking spare batteries in a purse or pocket.
- Custom-fitted compartments help keep batteries separated and contained.
- Slide-open closure intended to stay closed during daily carry.
- 3D-printed ABS construction is positioned for everyday durability.
Cons
- Only fits size 312 batteries, so it is not a universal battery organizer.
- Batteries are sold separately, so it will not function as a complete “battery kit” on its own.
What buyers think
Buyer-review evidence centers on convenience and day-to-day usability. Many shoppers describe the case as easy to carry (especially in a purse or pocket) and a noticeably better routine than opening battery packs when you need a quick change. Reviewers also highlight that it keeps batteries organized and separated, with a protective feel for transport.
There is also recurring feedback around handling and closure behavior. A small number of comments mention an initial difficulty getting the case to open on arrival, but the overall pattern still points to straightforward use after that. Overall, the review themes support that the case is mainly valued for portable storage and quick access, rather than as a complex accessory.
What this case is for
This is a compact storage container built specifically around size 312 hearing aid batteries. If your current method is to keep spare cells in the original packaging, this style of organizer can simplify the “need it now” moments by letting you load batteries once and then store them securely in a small case you can bring with you.
Key features that matter day to day
Slide closure for quick access
The case uses a simple slide-open mechanism. In practice, buyers like that it is easy to open and close, and that it is designed to remain closed during carry so batteries do not spill or rattle in your bag.
Separated compartments for organized storage
Instead of one open chamber, the interior uses custom-fitted compartments. Reviewers specifically mention that batteries do not touch each other, which is useful when you want clean separation for storage and easier loading or removal.
Pocket size, travel friendly form factor
With a slim profile and a small overall weight, the case is intended to fit in pockets, purses, or travel bags. It is also sized to function as a “spare batteries on hand” solution for everyday situations like commuting, running errands, or visiting family.
Pros and cons, beyond the hype
Where it performs well
- If you want faster battery swaps: Loading batteries into the case can reduce friction versus opening tamper-resistant packs each time.
- If you want better organization: Compartment separation is a practical benefit for keeping spares contained and easy to manage.
- If portability is your priority: The slim pocket form factor matches a typical “carry it with me” use case.
Where you might want a different option
- If you need multi-size compatibility: This is designed for size 312, so it will not be the right choice if you use different battery sizes.
- If you need a “ready-to-use” bundle: Batteries are not included, so you will need to buy cells separately.
Is the 3BP worth it?
The strongest reason to consider the 3BP is the combination of compact portability and compartment-style organization for size 312 hearing aid batteries. If you frequently change batteries and want spares that stay protected while staying easy to access, this kind of case can remove a lot of daily hassle.
If you only change batteries occasionally or you already prefer the original packaging method, you may not need an organizer. Also, if your hearing aids use a different battery size, you will want a case designed for that size instead.
