FAQs
What type of charger do I need for these batteries?
You need a charger specifically designed for 1.2V NiMH 9V E-block rechargeable batteries.
Can I use these batteries in any device that takes a 9V battery?
These are 9V E-block type batteries. While they fit the form factor, always check your device's manual to ensure compatibility with rechargeable NiMH batteries and the 1.2V nominal voltage.
How long do these batteries typically last on a charge?
The lifespan on a charge depends heavily on the device's power consumption. The 280 mAh capacity is suitable for many high-drain applications, providing longer runtimes than standard alkaline batteries.
How many times can these batteries be recharged?
NiMH batteries generally offer a good number of recharge cycles, typically several hundred, depending on usage and charging habits.
What does 'Low Self-Discharge' mean?
It means the batteries lose their charge very slowly when not in use. They retain a significant portion of their charge for extended periods, often up to a year.
Are these batteries safe for all electronic toys?
They are safe for electronic toys that require a 9V E-block battery and are compatible with rechargeable NiMH technology. Always consult the toy's manual.
What is the warranty period for these batteries?
Information regarding warranty is not provided in the product description. Please refer to the retailer or Ansmann's official website for warranty details.
Troubleshooting
Battery not charging
Ensure the charger is compatible with 9V NiMH E-block batteries and is properly connected. Clean the battery terminals and charger contacts.
Device not powering on
Verify battery orientation (+/-). Ensure batteries are fully charged. Test with a different set of known working batteries or a multimeter to confirm voltage.
Short battery life
The device may have a very high power draw. Ensure batteries are fully charged before use. Consider if the device is compatible with the 1.2V output of NiMH batteries.
Battery leaking or damaged
Immediately remove the battery from the device and the charger. Do not attempt to use or charge a damaged battery. Dispose of it responsibly.

- Suitable for a broad range of temperatures and applications
- Can be recharged multiple times, offering long-term value
- Supports fast charging for convenience
Cons
- Requires a compatible 9V E-block charger (not included)
- May not fit all 9V devices if internal dimensions vary

Setup, Compatibility & Care
Setup: Before first use, it is recommended to fully charge these batteries using a compatible 9V NiMH battery charger. Ensure the charger is designed for 1.2V NiMH E-block batteries. Insert the batteries into your device, observing the correct polarity (+ and - terminals).
Compatibility: These batteries are specifically the 9V E-block type. They are ideal for devices that explicitly use this form factor and voltage. Always check your device's manual to confirm compatibility with rechargeable NiMH 9V batteries.
Care: To maximize lifespan, avoid exposing the batteries to extreme temperatures outside the specified -20°C to +65°C range when not in use. Store them in a cool, dry place. If storing for extended periods, a partial charge is acceptable. Do not attempt to recharge if the battery casing is damaged. Clean the battery terminals periodically with a dry cloth if they appear corroded.
