Rechargeable battery 1.2V 900mAh Ni-MH AAA

Rechargeable battery 1.2V 900mAh Ni-MH AAA

Ni-MH 1.2V 900mAh AAA. Dimensions: 10 × 44 mm. Rechargeable cell for replacing a battery with matching voltage, chemistry and dimensions. Cell size and contact configuration are just as important as capacity when choosing a replacement.

What to check before buying

Compare the dimensions with the original battery and check the available space, polarity and contacts. A size designation helps identify a cell but does not guarantee compatibility with a particular device.

Check the contact shape and termination against the device battery compartment. If the assembly requires tabs, select a version explicitly supplied with them.

Replacement cells and battery-pack assembly

Suitable as a replacement or as part of a battery assembly only when the equipment design supports these specifications. Pack repairs must preserve the cell layout and count, insulation and original connections. Assembly should be carried out by qualified personnel.

Charging and safe use

Use only a charger or charging circuit suitable for the battery chemistry and configuration. Ni-MH and Ni-Cd are not automatically interchangeable. This is not a 3.6V or 3.7V lithium cell or a 1.5V alkaline battery.

Avoid short circuits and reversed polarity. Do not solder directly onto the cell body. When repairing packs, do not mix battery chemistries or combine new and used cells.

Buy the right replacement

Check the current price and availability on this product page. For selection assistance, send the original battery reference, dimensions and a photograph of its connections. Choose by specification rather than appearance alone.

Frequently asked questions

Is a 1.2V rating enough to ensure compatibility?

No. Chemistry, dimensions, contacts and the charging and discharge conditions supported by the equipment must also match.

Does more mAh mean more power?

mAh measures capacity, not maximum discharge current. Higher capacity does not guarantee compatibility, greater power or a specific runtime.

Is this a complete battery pack?

This page describes the listed cell, not a custom-assembled multi-cell pack. Check the stated product presentation before ordering.
