Rechargeable Ni-MH AA | AAA | 9V | C | D
Why buy batteries every month when you can recharge them hundreds of times? VIDEX Ni-MH rechargeable batteries (AA/AAA, etc.) are the ideal choice for Xbox controllers, camera flashes, and motorized children's toys.
The biggest benefits of rechargeable batteries:
- Massive TCO savings: One Ni-MH battery replaces hundreds of regular Alkaline batteries over time.
- Immediate use: Most batteries come pre-charged from the factory (Ready-to-use).
- No memory effect: Feel free to charge them at any time without waiting for a full discharge.

Q: What is the main advantage of NiMH rechargeable batteries compared to older generation NiCd elements?
Q: What does Low Self-Discharge (LSD / Ready-to-Use) technology mean and why is it crucial?
Q: Why are VIDEX NiMH batteries superior to alkaline batteries in professional photo flashes and wireless microphones?
Q: How to properly charge NiMH batteries to ensure their service life up to 1000 cycles?
Q: Why do rechargeable NiMH batteries work more effectively in sub-zero winter temperatures than standard alkaline batteries?
A: NiMH (nickel-metal hydride) batteries prevent the 'memory effect' and provide up to 30% more capacity in the same AA or AAA housing size. They do not contain toxic cadmium and can withstand up to 1000 charge cycles, drastically reducing the volume of single-use battery waste.
Q: What does Low Self-Discharge (LSD / Ready-to-Use) technology mean and why is it crucial?
A: LSD technology prevents rapid self-discharge: the battery retains up to 85% of its charge even after 12 months of storage on the shelf. Old generation NiMH batteries self-discharged by 30% in a month, whereas LSD NiMH elements are ready to use straight from the packaging.
Q: Why are VIDEX NiMH batteries superior to alkaline batteries in professional photo flashes and wireless microphones?
A: NiMH batteries have an extremely low internal resistance, allowing a photo flash to recharge 2 times faster between shots (under 1.5 seconds). Alkaline batteries overheat under high current peaks and take a long time to charge the capacitor, while NiMH maintains a constant 1.2V throughout the discharge cycle.
Q: How to properly charge NiMH batteries to ensure their service life up to 1000 cycles?
A: It is recommended to charge the batteries with a microprocessor-controlled charger that automatically cuts off the current after detecting a Delta-V (-ΔV) full charge. This prevents cell overcharging and overheating, protecting the electrolyte from thermal degradation.
Q: Why do rechargeable NiMH batteries work more effectively in sub-zero winter temperatures than standard alkaline batteries?
A: The nickel-metal hydride matrix of NiMH batteries maintains a lower internal resistance at low temperatures (down to -20°C) than alkaline water electrolyte. This means that in winter sports cameras and flashlights, the NiMH battery can deliver the necessary current without a rapid voltage drop.
