Varta Solar Ready2Use AA - 1.2V / 800mAh rechargeable battery (VAR56736B2) for solar garden lights

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 glance

• Optimised 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 application

The solar series is the perfect replacement for inferior original batteries outdoors:

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

Assembly & care instructions

• Choose correct capacity
  • Many 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 contacts
  • As solar lights are exposed to the elements, you should briefly clean the contacts in the device when changing batteries to minimise contact resistance.
• Winter storage
  • If you store your solar lights during winter, remove the batteries and store them in a cool, dry place to prevent deep discharge.

FAQs about the VARTA Solar Ready2Use AA

Can I also use these batteries in standard AA devices?

Yes.

• They work in any device that requires AA batteries. 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.
