Please check the smoke detector manual. In our opinion, almost every smoke detector will work with NiMH batteries, but please note: smoke detectors are equipped with a "battery empty alert", which emits an acoustic and visual sign when the battery is low. By using an alkaline or lithium battery, the signal may sound for a longer time (e.g. 3-4 weeks) whilst using NiMH batteries may only sound for 1-2 weeks.
ANSMANN NiMH AA Digital batteries are designed specifically for use in cameras. The high power requirements of cameras and the sometimes difficult conditions (such as extreme cold or heat) were taken into account.
Capacity specification on the label of non-rechargeable batteries is not usual. Background: depending on the type of use, the capacity of the battery varies significantly. For example, an AA Alkaline battery in a remote control can provide 2700mAh of energy. The value by using it in a digital camera is much lower, e.g. just 1500mAh.
To change phone batteries (DECT batteries), we recommend using new batteries with similar capacity to the original. They may not have the same capacity but should be similar; eg; original AA DECT batteries with 600-1000mAh exchange with ANSMANN AA DECT800, original AA DECT batteries with 1000-1600mAh exchange with ANSMANN DECT1300. Overloading the phone or base station by using batteries with slightly higher capacity is very unlikely.
Cordless phones usually have a display that indicates the battery status (the remaining capacity). In order to ensure a reliable indication, important information is used, such as supplied from the built-in charging circuitry. If a battery is charged out of the phone the necessary information from the circuitry is missing and the phone may not properly display the status of the battery.
Hearing aid batteries are zinc-air-batteries. To function correctly, they need oxygen from the surrounding air. They have a coloured sticker (or “tag”) which need to be removed 20-30-minutes before using the battery, so air can enter the battery allowing it to reach full power.
Over 99% of battery operated devices which work with 1,5V alkaline or zinc-carbon batteries will also work with NiMH batteries. Alkaline batteries are normally around 1.5V and by NiMH batteries are about 1,2V nominal voltage, but this isn’t the whole story. The voltage of a new Alkaline battery starts at just over 1,5V, but when you use it the voltage drops slowly to only 0,8V. A fully charged NiMH battery is about 1,4V and stays at 1,2-1,3V until the end of its capacity and then quickly drops to under 1,0V.
Some older devices require at least 1,3V to work. These, then, only work for a short time with NiMH batteries. Another reason could be that the battery display of devices such as digital cameras is set for Alkaline battery voltage and therefore displays NiMH batteries as empty.
Yes, all the ANSMANN Li-Ion-Batteries for digital cameras, camcorders, mobile phones and the ANSMANN power packs come with an electronic protective circuit, called a “Safety-Board”.
The protective circuit in ANSMANN Li-Ion batteries protects against following conditions:
Basically this is possible and makes financial as well as environmental sense. Devices such as digital cameras, MP3-Player, toys, torches, etc., normally work perfectly well down to 0.9V per cell. Therefore, using a rechargeable battery with a nominal voltage of 1.2V is a great replacement for an alkaline 1.5V battery.
This is normally perfectly ok to do but replacements should be of the same chemical composition and same capacity. It is not advisable to mix NiCd with NiMH or different capacities in the same device.
The Zero Watt technology separates the device from the mains so stopping any power consumption.
Do the BASIC series (Basic 5 plus, Basic 4 plus, Basic 2 plus) or the SMART series chargers (Smart, Smart Eco, MaxE Power) automatically cut off charging once the batteries are fully charged?
No, the BASIC and SMART series chargers are ANSMANN basic models without automatic cut-off. The charging time should be calculated manually. At the end of the calculated charging time please remove the fully charged batteries from the battery charger.
Can additional foreign mains input plugs be bought for our traveler plug system (for example POWERLINE 4 ZeroWatt)?
Please contact us using our service hotline.
The "refresh" function is a battery care program, extending the life of the battery and increasing its efficiency.
To work out the energy left in a battery the Energy Check loads the battery and averages several measurements taken. If the contacts are contaminated or not enough pressure is put on the battery an incorrect measurement may occur.
Deep discharged batteries are normally damaged and are therefore not recognized by some battery chargers or recognized as defective.
Some countries have several different plug systems. Please check the regional different plug systems before you travel to another country or, if in doubt, use a universal travel adapter, like the ANSMANN "All in One 3".
The device is optimized for charging batteries used in the same end product (such as digital cameras) and therefore the batteries are in the same state of charge or condition. For single battery charging, our POWERLINE series is perfect.
Check what voltage and current the end device needs to operate (to find these you may have to look at the instructions or on the device itself) and choose the right universal power supply. The output voltage of the universal power supply should be the same as the input voltage of the end device. The maximum output current of the universal power supply can be higher than the original one from the end device.
Both the connections work, but they are wired differently. One of the connections is optimized for charging Apple® devices and the other is for other products.
Modern NiMH batteries do not suffer from a significant memory effect like NiCd batteries do. Therefore there is no requirement to have a discharge function.
These two alternative technologies require different charging regimes to NiMH or NiCd batteries.
Yes. All the POWERLINE and ENERGY series have individual battery supervision. Therefore different battery types with different capacities and states of charge can be charged at the same time. Every charging slot continues until that battery is fully charged. After this there is an automatic switch to trickle charging mode.
All devices with intelligent charging control can have the batteries left in because these devices switch automatically to trickle charge mode once the battery is fully charged. This helps keep the batteries at 100% power. This also limits self-discharge of the batteries.
The BASIC series (trickle chargers) are also free from battery overload as the charging current is always low, but remains constant.
The chargers with wide range input (100-240V) can be used worldwide.
The ENERGY series is equipped with an automatic refresh program. During the first 10-15 minutes the battery is analyzed and then, if needed, the refresh program starts automatically. If the battery is okay the device switches automatically to charging (red light).
