# BCI Group 24 battery

**What replaces a BCI Group 24: Group 24, 24-**

12 V lead-acid, 260 × 173 × 225 mm

The BCI Group 24 is a rechargeable 12 V lead-acid prismatic. The codes below are the same physical cell sold under different manufacturer names, and any of them will fit.

## Specification

- **IEC designation:** BCI Group 24
- **Nominal voltage:** 12 V
- **Chemistry:** Lead-acid
- **Size:** 260 × 173 × 225 mm
- **Rechargeable:** Yes

## Codes that mean the same battery

*Different manufacturers, one physical battery. Voltage, chemistry and dimensions all match.*

| Code | Fits? |
| --- | --- |
| Group 24 | Yes — same cell |
| 24- | Yes — same cell |

## Codes that look close but are not

| Code | Why it is not a substitute |
| --- | --- |
| Group 24F | Thirteen millimetres longer and with the terminals reversed. That is the whole difference, and it is enough that the cables will not reach on the wrong one. The F suffix is what to check, not the 24. |
| Group 27 | Nearly 50 mm longer. More capacity, and it will not sit in a group 24 tray. |

## Where it turns up

- Older Toyota, Nissan and Honda models
- Marine deep-cycle and dual-purpose service
- RV house batteries
- Larger UPS and standby banks

### Can I use a Group 24F instead of a BCI Group 24?

Thirteen millimetres longer and with the terminals reversed. That is the whole difference, and it is enough that the cables will not reach on the wrong one. The F suffix is what to check, not the 24.
