KL Observer
If your old battery, device compartment or manual says CR1220, choose another CR1220 whenever possible. This is a stock-check and call-ahead guide, not a live inventory directory: photograph the old cell, verify its code and terminal format, check HomePro’s online listing, and confirm branch-level availability before setting out. If no practical HomePro outlet can confirm stock, CHAN LOCKSMITH SDN BHD in Puchong is a regional Klang Valley lead to call before travelling.
The short answer: match CR1220 exactly
Matching the exact code avoids relying on a similar-looking coin cell that may differ in thickness, chemistry, voltage, terminal arrangement or discharge behaviour.
A standard CR1220 is a 3V non-rechargeable lithium-manganese-dioxide coin cell measuring 12.5 mm in diameter and 2.0 mm high. Maxell identifies CR1220 as a distinct model and places primary CR cells and rechargeable ML cells in separate battery categories in its product-data directory.
Check these details before buying:
- Printed code: CR1220
- Nominal voltage: 3V
- Dimensions: approximately 12.5 mm × 2.0 mm
- Chemistry: primary lithium manganese dioxide
- Polarity: the replacement must sit in the specified direction
- Terminal format: loose, tabbed and solder-mounted cells are not automatically interchangeable
- Device instructions: the manual or battery-compartment marking takes priority
DL1220 and ECR1220 are commercially cited brand cross-references for CR1220, but that does not make them universally approved for every device. Compare the package specifications with the old cell and follow the device manufacturer’s instructions (commercial CR1220 cross-reference comparison).
Before leaving your hotel or home, photograph the old battery’s printed face, its position in the holder and any compartment markings. Those images give a seller more reliable information than a description of the device from memory.
Use this compatibility check before you buy
This table is a quick filter, not a substitute for the device manual.
| Code | Key difference | Buying decision |
|---|---|---|
| CR1220 | Exact primary-cell code and intended specification | Preferred choice |
| DL1220 | Commercial brand cross-reference | Confirm package and device specifications |
| ECR1220 | Commercial brand cross-reference | Confirm package and device specifications |
| BR1220 | Different chemistry and potentially different discharge behaviour | Use only if the device maker permits it |
| CR1216 | Thinner than CR1220 | Not a default substitute |
| CR1225 | Thicker than CR1220 | Not a default substitute |
| ML1220 | Rechargeable ML-series cell | Do not substitute unless explicitly supported |
| LIR1220 | Rechargeable cell with different electrical characteristics | Do not substitute unless explicitly supported |
CR1216 is 1.6 mm thick, CR1220 is 2.0 mm and CR1225 is 2.5 mm. Rechargeable LIR1220 cells can also have different electrical characteristics from a primary CR1220. These differences make code and device-specific confirmation more reliable than matching on appearance alone (CR1220 replacement comparison).
Do not force a battery into a holder or compress the cover to close it. A thinner cell may sit too loosely for reliable contact, while a thicker one may not seat correctly.
Start with HomePro’s exact-code listing and stock check
HomePro lists a GP lithium coin battery with the exact CR1220 code under SKU 1064602. The product page provides a “Check stock” function and an add-to-cart option. The captured listing displayed RM3.50, but that is not a guaranteed current checkout or outlet price. Check the live HomePro GP CR1220 product listing before planning your day.
The listing does not identify a particular Kuala Lumpur outlet with stock. Treat it as a way to begin an outlet search rather than confirmation that the closest branch has the battery.
Before changing your route, establish:
- Which outlet has the exact CR1220
- Whether the stock indication is current
- The current price
- Whether collection or advance ordering is required
- When the order will be ready
Use Puchong as a call-ahead Klang Valley fallback
CHAN LOCKSMITH SDN BHD lists an exact-code MAXELL CR1220 marked 3V and publishes the contact number 012-505 9319. Its product page directs customers to call for details but does not establish current branch-level stock, price, opening hours or collection arrangements (MAXELL CR1220 product listing).
The business publishes these Puchong addresses on its first-party site:
- Main address: Lot 5-1, Blok 1, Sierra Fresco, Jalan Sierra 10/1, Bandar 16 Sierra, 47120 Puchong, Selangor
- Bandar Kinrara branch: Lot G-33, Giant Hypermarket Bandar Kinrara, Jalan BK 5A/1, 47100 Puchong, Selangor
- Bandar Bukit Puchong branch: Tesco Bandar Bukit Puchong OL-G2A, Jalan BP 7/1, Bandar Bukit Puchong, 47120 Puchong, Selangor
These are Puchong, Selangor locations, not central Kuala Lumpur outlets. Treat them as regional Klang Valley leads and verify the exact branch and collection arrangements through the CHAN LOCKSMITH website before making the journey.
Check fit and polarity before closing the device
Follow the device manual where available. Otherwise, keep the replacement process controlled:
- Power the device off before opening it.
- Photograph the old cell in place, including which side faces upward.
- Remove it without bending the holder or attached terminals.
- Check that the package and replacement cell display the expected code and voltage.
- Install the new cell in the same polarity orientation as the old one.
- Stop if it sits unevenly, moves loosely or prevents the cover from closing.
- Test the device before completing final reassembly.
