Beschreibung
A drawer full of dead batteries is not a storage problem. It is a decision you have already made — to keep buying energy instead of keeping it. The Constant is an eight-pack of 2600mAh NiMH AA rechargeable batteries engineered to end that cycle, delivering 1.2V of steady, repeatable power across more than a thousand charge cycles before it even begins to think about retirement.
The chemistry does the talking. Nickel-metal hydride cells hold a charge between uses far better than older rechargeable generations, which means the batteries in your flashlight are ready when the power goes out, not dead from sitting. The 2600mAh capacity comfortably outlasts standard alkaline cells in the devices that drain them fastest — digital cameras, portable speakers, game controllers, toys, and remote controls. With a low self-discharge profile and CE certification, these are cells built for the drawer, the emergency kit, and the everyday.
What makes the Constant a system rather than a purchase is the included pair of AA battery case boxes. Organize charged cells, keep spares from rattling loose in a bag, and know at a glance what you have ready to go. Eight cells, two storage cases, one thousand-plus cycles each — a single set replaces hundreds of disposable batteries over its life, which makes the Constant cheaper per watt than the alkaline aisle and a great deal kinder to the landfill.
The best battery is the one you never have to buy again.

Application Scenarios
Photographers who burn through AA cells on shoots, parents who have learned that toys eat batteries faster than snacks, households stocking emergency kits that must actually work when the lights go out, and gamers who refuse to keep a drawer of half-dead alkalines — the Constant serves everyone whose devices outnumber their outlets. Keep one case of charged cells by the door and one in the kit, and the question of whether the batteries are ready stops being a question. The included storage cases make rotation simple: mark one case ready and one charging, and the system runs itself. From camera bags to kitchen drawers, the Constant turns battery management from a weekly chore into a twice-a-month habit.
Frequently Asked Questions
Q: Do I need a special charger?
A: No. Any standard NiMH AA charger works with these cells. Most smart chargers also handle individual-cell charging, which keeps the whole set balanced.
Q: How long do they hold a charge when not in use?
A: NiMH cells have a low self-discharge rate, so they hold most of their charge for weeks to months of storage — ready for flashlights, remotes, and emergency kits alike.
Q: Are they better than alkaline batteries?
A: For repeated use, yes. Each cell supports over 1000 charge cycles, so one set replaces hundreds of single-use alkalines — better value and far less waste.
Q: Can I use them in high-drain devices?
A: Yes. The 2600mAh capacity and 2A discharge capability handle digital cameras, game controllers, and other high-drain electronics without sagging.
Q: Do the batteries come pre-charged?
A: They may arrive with a partial charge from the factory. We recommend a full charge cycle before first use for maximum runtime.
Q: Can I use these batteries in children's toys?
A: Absolutely — toys are one of the heaviest battery drains in any household, and rechargeables are the economical answer. Just make sure cells are inserted with the correct polarity, and supervise young children around battery compartments.
Q: How should I store the batteries when not in use?
A: Keep them in the included storage cases in a cool, dry place away from direct sunlight and extreme temperatures. Stored properly, NiMH cells hold their charge for weeks to months between uses.
Q: Do NiMH batteries suffer from memory effect?
A: Modern NiMH cells show minimal memory effect, so you can recharge them at any point without waiting for a full discharge. This makes them far more convenient than older rechargeable chemistries.
Q: What is the environmental benefit of switching?
A: Each cell supports more than 1000 charge cycles. Over its life, a single 8-pack replaces hundreds of single-use alkaline batteries — keeping toxic heavy metals out of landfills and cutting the cost of powering everyday devices.
