Varta
The Varta Solar Ready2Use AA (Model VAR56736B2) rechargeable batteries were specifically developed for the special requirements of solar-powered garden and outdoor lights. These devices are often faced with a challenging environment: low charging currents due to small solar panels and frequent, shallow charging cycles.These batteries feature an optimised capacity of 800 mAh, which is perfectly matched to the energy intake of standard solar lights. Thanks to the "Ready2Use" technology, they are immediately ready for use and offer extremely high cycle stability for a long outdoor lifespan.Highlights at a glanceOptimised for solar charging: Specially designed to efficiently absorb energy even at very low currents (little sunshine).Ready2Use technology: The batteries are already pre-charged and can be inserted into the light straight away.High cycle stability: Developed for daily charging and discharging over many years.Sustainable & economical: Replaces hundreds of disposable batteries and, thanks to rechargeability, is environmentally friendly.Low self-discharge: Retains energy much better than conventional NiMH batteries during longer periods of bad weather.No memory effect: The batteries can be recharged at any time without permanently lowering their capacity.Areas of applicationThe solar series is the perfect replacement for inferior original batteries outdoors:Solar garden lightsReplaces old batteries in path lights, solar spots, and decorative outdoor lights.Solar string lightsReliable energy source for LED string lights on balconies or in the garden.Low-current devicesAlso suitable for other devices with low energy demand, such as remote controls or wall clocks.Assembly & care instructionsChoose correct capacityMany solar lights cannot fully charge batteries with very high capacity (e.g. 2600 mAh). The 800 mAh of these VARTA batteries ensures the solar cell can actually fully charge the battery during the day.Cleaning the contactsAs solar lights are exposed to the elements, you should briefly clean the contacts in the device when changing batteries to minimise contact resistance.Winter storageIf you store your solar lights during winter, remove the batteries and store them in a cool, dry place to prevent deep discharge.

However, their strengths (the optimisation for weak charging currents) are especially evident in solar applications.Why do these batteries have a lower mAh than other AA batteries?This is a technical advantage for solar lights.Most solar panels in garden lights are too weak to fully charge a 2500 mAh battery in one day. A battery that is constantly only partially charged wears out more quickly. 800 mAh is the "golden mean" to provide light for an entire night and to be reliably fully recharged during the day.How long do these batteries last outdoors?Several years.Depending on the quality of the solar light and location, these special batteries last significantly longer than standard NiMH cells as they cope better with irregular charging cycles.

Main applications are cordless phones (DECT), mobile data collection devices, medical monitors and other professional handheld devices. It is usually used in multi-cell packs (e.g. with 2.4V or 3.6V).How is this NiMH cell charged?NiMH cells are typically charged with a constant current. Charging must be done using suitable charging electronics, which monitor the charging process and terminate it safely by methods such as -deltaV (voltage drop) or temperature monitoring to prevent overcharging.What does "assembly" mean?Since this is a single industrial cell, it is generally not used directly. During assembly, several cells are combined into a battery pack with the desired voltage and capacity (e.g. by welding), provided with protective insulation, and fitted with the appropriate connection cables and plugs.How should this battery cell be disposed of?Batteries must not be disposed of with household waste. As an industrial battery, it is subject to the regulations of the Batteries Act. Please take the used battery cell to the designated industrial or municipal return points to ensure proper and environmentally friendly recycling.

"Upright" means that the cell is mounted vertically on the PCB. "KM" often stands for contact material, in this case the solder pins. "-/++" describes the arrangement of the poles, and "8mm" is the typical distance between the two solder pins, which allows integration into an existing circuit board layout.What are the advantages of upright mounting?Upright (vertical) mounting minimises the required footprint on the circuit board compared to horizontal mounting. This is a decisive advantage in very compact devices where every millimetre counts.Is this cell suitable for charging with external chargers?No, this assembled industrial cell is designed for permanent installation and charging via a defined charging circuit within a device. It is not intended for handling by end-users or for use in standard chargers.For which soldering methods is this assembled cell suitable?The cell with solder pins is suitable for hand and wave soldering. Use in the reflow soldering process is only possible under strictly controlled temperature conditions, as high temperatures can damage the cell. Please follow the manufacturer's processing instructions.How must this battery cell be disposed of?Rechargeable batteries must not be disposed of in household waste. As an industrial battery, it is subject to the regulations of the Battery Act. Please hand over the used rechargeable cell to the industrial or municipal collection points provided for this purpose to ensure appropriate and environmentally friendly recycling.
