2V1000Ah solar energy battery

1.BATTERY PROPERTIES

Maintenance free

As it is value-regulated .sealed and glass mat is utilized .acid is trapped inside . so refilling is not needed and is leak proof.

NO Memory Effect

Some batteries say nickel –cadmium batteries.will become conditioned to provide less power after repetitious short usage /discharge .

No memory effect 

Some batteries .say nickel –cadmium batteries will become conditioned to provide less power offer repetitious short usage /discharge

Low self discharge

The self –discharge rate for HENDA SLA . battery is about 2-3% per month at room .temperature compared with 20-30% for other common battery systems .

Longer service life

Utilized thick and massive calcium grate ensure that HENDA SLA battery has a longer service life over 15years .

High discharge rate .

Since the internal resistance is low .the battery can provide high rate of discharge

Wide operation temperature range

HENDA sla battery capacity is rated at 20°C , and will operate from 15°C (5f)+50°(C (122F)when it is fully charged Ambient temperature is 20°C.service life will be more efficient under 15’C to 25”C .

29years history Battery manufacturer 

Lead (material)- Lead Plate - Battery Case all from our producing .
