Battery Care/Long Term Storage, Li-Ion Batteries

Section 7 - Battery Care/Long Term Storage

Battery Care

To ensure the long life and safe handling of the Li-Ion battery within the BTR-24 and TR-24 please following the following precautions:

1.Store the TR-24s and BTR-24 in a clean, cool, dry location away from heat.

2.Do not store for extended periods of time in direct sunlight.

3.Do not disassemble the battery packs within the TR-24 or BTR-24.

4.Do not apply solder directly to the pack.

5.Do not puncture/crush or subject the TR-24 or BTR-24 to excessive impact.

6.Dispose of unit in proper recycling location for a device with a Li-Ion battery.

Long Term Storage

“Long term storage” of the system is defined as no use of the system for 1 month or longer. Due to the internal Li-Ion batteries of the TR-24 and BTR-24, care should be taken in long term storage. Use the following steps to ensure the best performance of the system after it comes out of storage.

1.After the last event:

•If the TR-24 or BTR-24 batteries were used for four hours or less then do not recharge the internal TR-24 or BTR-24 batteries. (Please see the discussion of “Li-Ion batteries” in the follow part of this section as to why)

•If the TR-24 or BTR-24 batteries were used for more then four hours then recharge the internal TR-24 or BTR-24 batteries for two hours then take them off charge (Please see the discussion of Li-Ion batteries in the follow part of this section as to why)

2.Store the TR-24s and BTR-24 in a clean, cool, dry location away from heat. The temperature of the storage location should not rise above room temperature. The recommended temperature range of the storage location is 32 - 77° F (0 – 25° C).

3.Every 6 months charge the BTR-24 and TR-24 for three hours then take off charge. Do not fully charge. This prevents the battery from over discharging and helps maintain the battery’s performance.

Li-Ion Batteries

The Li-Ion batteries used in the TR-24 and BTR-24 are excellent batteries for portable, indoor/outdoor applications. They have a high energy density (energy per weight) compare to other rechargeable battery technologies (NiCd, NiMH, Alkaline, Gel Cells), are low maintenance, and offer superior performance at low temperatures.

For best performance after long-term storage, Telex recommends the batteries be charged to 30% - 50% of capacity before being placed in storage. This is the typical battery capacity left after 4 – 6 hours of full duplex use. Li-Ion batteries retain nearly all their capacity if stored for long term in dry, cool temperatures with only 30% to 50% charge. They can lose up to 20% capacity if stored for long term right after being fully charged.
