This replacement battery offers 1500 mAh of capacity and uses lithium-polymer technology, designed for several Huawei routers and mobile hotspots, including the E5330, E5336, E5377, E5573, E5575, E5577C, R216 and R218 models.

Lithium-polymer batteries are a variant of lithium-ion technology. They are light and can be made in thin, flexible shapes. They can be recharged many times and lose little capacity over repeated charge cycles compared with older battery types.

The battery weighs about 30 grams and is supplied as a single unit. The 1500 mAh rating gives an indication of how long the router can run, although the actual operating time depends on usage and signal strength.
