r-tec Battery Kit is the backup power module ensuring operation continuity of automation products during power outages. Comes as a 24 V lead-acid battery + charger board combination; works integrated with the standard battery terminals of G24, R2, GIGA Sedo control boards. Standard accessory for sites where uninterrupted operation is critical such as hospital, mall, airport, secured estate.
In which scenarios is it mandatory?
| Site type | Battery requirement |
|---|---|
| Hospital automatic door | Mandatory — uninterrupted patient entry |
| Airport transit | Mandatory — passenger safety |
| Barrier (logistics 7/24) | Mandatory — terminal flow |
| Villa garden (remote) | Recommended — night outage entry |
| Mall shop door | Recommended — backup during business hours |
| Industrial sectional | Optional |
| Office internal door | Optional |
7 Ah vs 12 Ah — capacity selection
Battery capacity is proportional to the connected motor + cycle count:
| Motor | 7 Ah battery cycle | 12 Ah battery cycle |
|---|---|---|
| COUPER 24 / 85 W | 50-80 | 100-150 |
| PRINCE 24 / 150 W | 30-50 | 60-90 |
| KING 524F sliding | 30-50 | 60-80 |
| Barrier (190 W) | 20-30 | 40-50 |
| Automatic door (100 W) | 80-120 | 150-200 |
→ 7 Ah sufficient for standard residence; 12 Ah mandatory for industrial / 7-24 operation.
Automatic switchover — uninterrupted
The battery kit works in the logic of uninterruptible power supply (UPS):
- Mains normal → board continuously trickle-charges the battery
- At moment of mains outage → board automatically switches to battery supply (< 50 ms delay)
- Door operates uninterrupted → user does not notice outage
- Mains restored → board returns to charging mode
→ Door owner/operator does not even notice the outage — critical operation continues.
Battery life and replacement
Standard lead-acid battery (VRLA AGM) life is 3-5 years (200-300 cycles annual average). End-of-life indicators:
- Battery voltage drops — 22-23 V instead of 24 V when full
- Cycle count decreases — 10-15 cycles instead of 30-50 during outage
- Charge time extends — 16 hours instead of 8 hours
- LED persistent charging — “Weak battery” warning
→ When indicators are seen, time for renewal; aging battery also strains board charge circuit.
Field discipline
- Battery location — Next to control board, in a place with air circulation; hot environment shortens battery life
- Voltage test — Battery voltage measurement with multimeter once every 6 months; renew if below 22 V
- Charge circuit check — Is “charging” LED status continuously on? Continuous charging = board malfunction
- Emergency discharge test — Once a year mains turned off and battery cycle count measured (test cycle)
- Storage temperature — Backup battery stock kept in 0 – +25 °C environment
- Environmental waste — Old battery is not standard disposal, delivered to lead-acid waste centre (legally mandatory)
- Periodic maintenance — Annual general battery + charge board + connection check
Frequently Asked Questions
Below we've compiled the most common questions and answers regarding this product.
-
How many cycles does the gate keep running during an outage?
It depends on battery capacity and the motor: the 7 Ah option carries 30 to 50 cycles and the 12 Ah option 50 to 150. The width of those ranges comes from motor type, as a motor carrying a heavy leaf draws more energy per cycle. The system is built on 24 V DC with two 12 V VRLA AGM batteries, and charging current is managed automatically between 0.5 and 1 A. Overcharge, deep discharge and short circuit protection are standard. At facilities where an outage may last a long time, it is sound practice to plan the 12 Ah option together with a manual release route.
-
How often should the battery be replaced?
In standard use the life is 3 to 5 years. A lead-acid battery loses capacity without visible warning: everything looks normal right up to the outage, and then the expected number of cycles does not materialise. The battery is therefore replaced on a schedule rather than on failure, and the installation date should be written on the enclosure. Temperature affects life directly; the operating range is -10 to +50 °C, and a battery in an enclosure exposed to sun tires sooner. The most reliable check is to simulate an outage at annual maintenance and measure the real cycle count.
