NiMH Battery Technology

Information

Listen LA-362 NiMH batteries are industrial grade and provide constant current to Listen products. These batteries provide 2100 milliamp hours (mAh) of storage capacity. When used with Listen supplied batteries, Listen products should provide the following operational time after batteries are fully charged:

Receivers: 15 hours

Transmitters: 8 hours

Listen recommends that new batteries be put through two-charge cycles prior to use.

Nickel Metal Hydride (NiMH) batteries have no memory effect, so each charge offers full recharge capacity.

NiMH batteries can be repeatedly charged to full capacity from any level of capacity. NiMH batteries typically maintain optimal performance for 500 to 700 charge cycles. Listen recommends that batteries be replaced after 2 years of service or whenever the batteries no longer hold a charge.

Please note that NiMH batteries should be recharged if they have been sitting idle for more than two months, as they lose around 20-30% of their charge each month.

To avoid battery discharge while not using Listen products, it is recommended to leave units in a powered case, as the maintenance charge will ensure the batteries remain at full charge. Make sure the case lid remains open or removed. The charging process generates heat and ventilation is required.
