Varta NiMH Longlife Battery 56703 – Reliable energy in a 2-pack blister pack

The Varta NiMH Longlife batteries (model 56703) in AAA format (Micro) are the ideal solution for devices with constant but relatively low energy requirements. As part of the "Ready2Use" series from Varta, they combine the advantages of disposable batteries with the sustainability and cost-effectiveness of rechargeable batteries.

These rechargeable batteries are characterised by particularly low self-discharge, which means they are immediately ready for use even after months of storage. With a capacity of 800 mAh they offer solid performance for everyday household use.

Highlights at a glance

• Ready2Use technology: The batteries are pre-charged and can be used immediately after unpacking.
• Extremely low self-discharge: Retain up to 80% of their capacity after 12 months of storage (without intermediate charging).
• Longevity: Rechargeable hundreds of times, which is not only easy on your wallet, but also on the environment.
• No memory effect: The batteries can be recharged at any time, regardless of the current state of charge.
• High compatibility: Fit in any standard NiMH battery charger and in any device that requires AAA/micro batteries.

Typical areas of application

The "Longlife" series is particularly optimised for "low-drain" devices in which batteries are often left for a long period of time:

• Remote controls & controllers
  • Constant performance for TV remotes or smart home hubs.
• Wall clocks & alarm clocks
  • Long operating times without the need to constantly change batteries.
• Cordless phones (DECT)
  • Ideally suited as a replacement battery for handsets that are regularly left in the charging station.
• Computer accessories
  • Reliable power for wireless mice and keyboards.

Assembly & care instructions

• First charge
  • Although they are pre-charged, NiMH batteries usually only reach their full capacity after the first three to five charging and discharging cycles.
• Avoid deep discharge
  • Do not store the batteries discharged for years. Regular use or a quick recharge every 12 months will significantly extend their lifespan.
• The right charger
  • Use a modern charger with single slot monitoring and automatic shut-off (Minus-Delta-U) to prevent the cells from overheating.

FAQs about the Varta NiMH Longlife battery

Do these rechargeable batteries replace normal 1.5V batteries?

Yes. Although rechargeable batteries have a nominal voltage of 1.2V, their discharge curve is flatter than that of 1.5V alkaline batteries. They work flawlessly in almost all electronic devices and often last longer than conventional batteries.

Can I use these batteries in my DECT phone?

Yes, ideally. The capacity of 800 mAh corresponds exactly to the standard of many cordless phones. Just ensure that your phone requires AAA rechargeable batteries.

How do I dispose of the batteries at the end of their service life?

Via collection boxes in shops. Batteries must never be disposed of in household waste. Use the green collection boxes provided in shops (supermarkets, DIY stores) for proper disposal.
