Tabla de tamaños de grupos de baterías BCI (Grupo 24, 27, 31, etc.)

.”BCI Battery Group Size” refers to the Battery Council International (BCI) standard for categorizing automotive batteries based on their physical dimensions, terminal placement, and voltage. BCI group sizes are used to ensure compatibility between batteries and vehicles. Each group size corresponds to a specific set of dimensions and terminal configurations, allowing consumers to select the appropriate battery for their vehicle. Common group sizes include Group 24, Group 35, Group 49, etc.

Understanding Battery Group Size Chart

Understanding the Chart: The Battery Group Size Chart standardizes batteries based on dimensions, including length, width, height, and polarity. Each number corresponds to different size sets, with larger numbers indicating bigger batteries.
Choosing the Right Size: Consult your owner’s manual or reliable online sources to identify the correct size for your devices.
Impact of Incorrect Sizes: Choosing the wrong size can lead to problems. Small batteries may not provide sufficient power, while large ones could damage wiring.

When replacing an old battery with a new one, make sure the new battery is the same type as the old one or it’s confirmed to be a direct replacement. Also, check that the new battery has the same or better electrical capabilities.

Baterías pequeñas de ciclo profundo/de uso general de 12 V

Las baterías pequeñas de ciclo profundo/de uso general de 12 V son en su mayoría baterías selladas de plomo-ácido (SLA) o de fosfato de hierro y litio (LiFePO4), que normalmente se utilizan en dispositivos UPS, alarmas, juguetes, sillas de ruedas y similares.

Los modelos más populares son baterías con capacidades más pequeñas, normalmente de hasta 30-35 Ah, donde entran en juego las baterías estándar del grupo U1 y U1R.

Si está buscando baterías de ciclo profundo/de uso general aún más grandes, considere uno de los grupos de baterías más grandes, como los grupos 24, 27, 31, etc.

¿Qué sucede si uso una batería de tamaño de grupo incorrecto?

El uso de una batería de tamaño de grupo incorrecto para su vehículo puede provocar varios problemas:

Problemas de instalación : Las baterías vienen en diferentes tamaños y formas. El uso de una batería con el tamaño de grupo incorrecto puede no encajar correctamente en el compartimiento de la batería de su vehículo. Esto puede provocar daños físicos a la batería, al vehículo o a ambos.
Compatibilidad eléctrica : Las baterías están diseñadas para proporcionar un voltaje y una capacidad específicos adecuados para el sistema eléctrico del vehículo. El uso de una batería con especificaciones incorrectas puede provocar problemas eléctricos como carga insuficiente o sobrecarga, lo que puede dañar componentes electrónicos sensibles como el alternador o el sistema del vehículo. sistemas informáticos.
