Applications for Delta HRL 12-12 batteries
The country of manufacture of Delta products is China. Has been working in the Russian market since 2001. Delta HRL 12-12 is a sealed lead acid battery with a capacity of 12 ah and an output voltage of 12 Volts. The main scope of the use of batteries - uninterruptible power systems, data centers, communication services.
Applied technologies and their features
For the manufacture of the Delta HRL 12-12 battery, AGM technology was used, instead of the usual liquid electrolyte, the compartments were filled with a special porous fiberglass filler, which was already saturated with electrolyte.
Thanks to the special manufacturing technology, the device received the following advantages:
- Can be placed in any position except upside down;
- the possibility of using the device in conditions of increased vibration;
- subject to operating rules, there is no gas emission and explosion hazard is excluded;
- the battery operates at low temperatures up to -30º C.
The disadvantages of the Delta HRL 12-12 battery are common to all lead-acid power supplies:
- heavy weight;
- the presence of a special charger;
- inadmissibility of storage in a discharged state;
- sensitivity to recharge;
- voltage drop in frost;
- lead oxide toxicity.

How to use a battery
The battery operating rules are developed by the manufacturer. When working with Delta HRL 12-12, the following standards must be adhered to:
- The optimum temperature in the room is 21–23 ºС.
- During operation of the device, its discharge is monitored. At values below 9.6 volts, it is necessary to put it on charge.
- The battery can be discharged with a current not exceeding the maximum permissible value specified in the technical data sheet.
- In order to prevent a decrease in the battery capacity below the nominal, charging starts when the discharge is incomplete.
How to charge a Delta HRL 12-12 battery
Charging parameters are applied to the device case:
- the maximum current when charging is 3.6 A;
- full charge time is 10 hours.
- if during charging the battery has warmed above 50 ° C, the process is stopped or switched to a gentle mode (reduce voltage).
The correct life of the battery depends on the service life during operation.

Ivan
Good quality at a reasonable price. True, there are failures, but this is more an exception than a pattern. This is not the first time I have been using Delta HRL 12-12 batteries in my business; customers are satisfied. I recommend.
Sergey
Overall a great and inexpensive product. But the labeling is not entirely clear, especially the release date. Sometimes it can cause the purchase of an old battery.
Gennady
No complaints. I have been using it for a long time. I advise friends and acquaintances. Decent quality at a nice price.
