Varta Solar Ready2Use AA - 1.2V / 800mAh rechargeable battery (VAR56736B2) f

The VARTA Solar Ready2Use AA (model VAR56736B2) batteries have been specifically developed to meet the unique requirements of solar-powered garden and outdoor lights. These devices often operate in challenging conditions: low charging currents due to small solar panels and frequent, shallow charging cycles.

These batteries feature an optimised capacity of 800 mAh, perfectly matched to the energy absorption of standard solar lights. Thanks to the "Ready2Use" technology, they are ready for immediate use and offer extremely high cycle stability for a long outdoor service life.

Highlights at a glance

• Optimised for solar charging: Specially designed to efficiently absorb energy even with very low currents (little sunlight).
• Ready2Use technology: These batteries are pre-charged and can be put directly into the light.
• High cycle stability: Designed for daily charge and discharge for years to come.
• Sustainable & economical: Replaces hundreds of disposable batteries and protects the environment thanks to their rechargeability.
• Low self-discharge: Retains energy much better than conventional NiMH batteries, even during extended periods of bad weather.
• No memory effect: The batteries can be recharged at any time without permanent capacity loss.

Areas of application

The Solar Series is the perfect replacement for low-quality original batteries in outdoor settings:

• Solar garden lights
  • Replaces old batteries in pathway lights, solar spots or decorative outdoor lights.
• Solar string lights
  • Reliable power source for LED string lights on balconies or in the garden.
• Low-power devices
  • Also suitable for other low-power devices such as remote controls or wall clocks.

Installation & maintenance instructions

• Select the correct capacity
  • Many solar lights cannot fully charge batteries with a very high capacity (e.g. 2600 mAh). The 800 mAh of these VARTA batteries ensures that the solar cell actually charges the battery completely during the day.
• Cleaning the contacts
  • As solar lights are exposed to the elements, when changing the battery quickly clean the contacts in the device to minimise contact resistance.
• Winter storage
  • If you store your solar lights in winter, remove the batteries and store them in a cool, dry place to avoid deep discharge.

FAQs about the VARTA Solar Ready2Use AA

Can I use these batteries in standard AA devices?

Yes.

• They work in any device requiring AA batteries. However, they display their strengths (designed for low charging currents) particularly in solar applications.

Why do these batteries have less mAh than other AA batteries?

That is a technical advantage for solar lights.

• Most solar panels in garden lights are too weak to fully charge a 2500 mAh battery in a day. A battery that is only ever partially charged wears out faster. 800 mAh is the "sweet spot" to provide light all night long and reliably reach a full charge during the day.

How long do these batteries last outdoors?

Several years.

• Depending on the quality of the solar light and the location, these special batteries last significantly longer than standard NiMH cells since they cope better with irregular charging cycles.
