The cycle life of DJ500 battery (2V500Ah) at 80% discharge depth is more than 1200 times:

Each Reese cell provides a specified capacity rating at full load.

After high current discharge, the battery pole should not be fused, and its appearance should not be abnormal.

Reishi battery has strong overcharge capacity and overcharge life. After continuous charging with 0.3I10 current for 16h, the appearance should be free from deformation and seepage. Overcharge life should not be less than 210D.

Richard battery at -30℃ and 65℃ sealing agent should not crack and overflow.

The Reese battery shall be suitable for access to on-line status detection devices.

Richard battery structure should ensure that during the service life, shall not leak electrolyte.

Reishi battery automatic discharge rate is not more than 3% per month (20℃).

The acid fog proof performance of the reishi battery should meet the requirement that the battery is continuously recharged with 0.2I10 current for 4h after being fully charged, and the PH value is neutral.

The cycle life of 80% discharge depth of Reese battery is more than 1200 times.
