Panasonic AAA NiMH 700 mAh 12-pack

These Panasonic HHR-70AAA cells are flat-top AAA NiMH rechargeable batteries rated at 700 mAh and 1.2 V. They suit devices that need standard AAA dimensions and a flat positive terminal. The pack contains twelve pre-charged units ready for immediate use in compatible electronics.

Flat-top terminal installation notes

Insert each cell following the device polarity markings; the flat positive end must contact the correct spring or plate. A common issue is confusing flat-top cells with button-top variants, which can prevent contact in tight compartments. Ensure the battery sleeve is intact to avoid short circuits against metal surfaces.

Check device compatibility before ordering

Verify that your equipment accepts flat-top AAA NiMH cells and operates at 1.2 V nominal voltage. Some devices require button-top terminals or alkaline voltage profiles and will not work reliably with this format. Confirm the battery compartment fits standard AAA dimensions without modification.

Questions about this item

How can I confirm the 12-pack AAA NiMH batteries are holding a full 700 mAh charge after the first charging cycle?

Charge the cells completely, then run a device until it stops; a healthy pack should deliver close to the rated 700 mAh before voltage drops below 1.2 V.

What comes in the box and do I need to buy a charger separately?

The package contains 12 flat-top AAA NiMH cells pre-charged to about 85 %; a compatible NiMH charger is not included and must be purchased separately.

Should I choose the 700 mAh flat-top version or look for a higher-capacity AAA for my high-drain device?

The 700 mAh flat-top model supports a high discharge rate and up to 1000 recharge cycles, making it suitable for high-drain use; higher-capacity AAA cells are a different product not covered here.
