Panasonic LC-P Series VRLA Cross-Reference: CHISEN 6-GFM Replacement Dimensions

What actually closed, and what it means for spares

The Shenyang plant produced the full LC standby float range. Its closure does not affect Panasonic’s automotive or two-wheeler business — it affects exactly the batteries used in float standby applications: telecom DC power, small UPS, switchgear, and substation auxiliary supplies.

For a maintenance buyer, the practical consequence is simple: every LC-series battery you can still buy is stock from a closed factory. Lead time stretches, allocation tightens, and price rises as remaining inventory is drawn down. A part number that was routine five years ago is now a sourcing problem.

The dimension reference below lets you qualify an alternative in ten minutes rather than ten weeks.

Dimension-level cross-reference: LC-P → 6-GFM

All measurements are millimetres, L × W × H / total height. Capacities are at 20-hour rate unless noted.

How to read “drop-in” versus “near-fit”: drop-in means every dimension is within 3 mm, so the battery sits on the existing tray, uses the existing terminal clearance, and needs no bracket work. Near-fit means length or width is within 5–15 mm — usually fine, but confirm your shelf depth and any cable gland clearance before committing.

Terminals match across this range. Both use the same M5, M6 and M8 internal-thread terminals in the corresponding sizes, so the cable lugs stay as they are.

High-power LC-PH: the same footprint, higher discharge

The LC-PH series is the 12-minute-rate high-power branch of the same range. It shares the LC-P dimensions, so the physical fit is identical — the difference is discharge performance under short high-current load.

If your load is genuinely short-duration high current — generator starting, large inverter ride-through, telecom DC boost — ask us for the 15-minute discharge curve rather than relying on the Ah figure alone. A 65 Ah cell can be built for either 200 W or 45 W at 15 minutes, and those are not the same battery.

What has no one-for-one equivalent

Two parts of the LC range do not map onto a standard 12V tray, and we would rather say so than sell you a part that will not fit.

LC-MH and LC-QA, 205 Ah and above. These 15-year and 17-year designs run up to 950 Ah. Our 12V VRLA range tops out at 250 Ah, so from 300 Ah upward the correct answer is a 2V cell configuration — either our 2V GFM tubular range (2V 80–3000 Ah) or 2V OPzV depending on whether the duty is float-critical or cycle-critical. In a 12V string, six 2V cells replace one 12V unit, and the footprint becomes a rack question rather than a tray question.

FXH/FTN-style narrow rack cells. Yuasa and Panasonic both sell 100 mm-thick rack-mount formats (278×103×197, 508×106×236). These are a different mechanical product, not a different size of ours. If your cabinets are built around that format, the realistic options are a custom build or a cabinet redesign.

For LC-MH and LC-QA duty specifically, ask about our GFMJ gel series rather than the AGM GFM. Gel chemistry carries better float life and better tolerance of deep discharge, which is exactly what those 15-year and 17-year duty profiles are specified for.

Frequently asked questions

Are CHISEN 6-GFM batteries really dimension-compatible with Panasonic LC-P? For the 17–65 Ah range, yes — the physical dimensions match within 3 mm and the terminals are the same type. For 100–220 Ah, the match is within 5–15 mm, which usually works but should be checked against your tray and cable clearance.

What happens to my existing wiring and tray? Nothing changes for the 17–65 Ah range. The tray, the terminal clearance and the cable lugs are all unchanged. Above 100 Ah, check total height on the 100D and 120B footprints because the cabinet depth differs from the Panasonic original.

Can I mix Panasonic and CHISEN batteries in one string? We do not recommend mixing brands within a single series. Cells from different manufacturers can differ in internal resistance and self-discharge current, and a mixed string ages unevenly. Replace the full string, or at minimum the full bank that discharges together.

What certifications do the replacements carry? Our VRLA range is tested to IEC 60896-21 and IEC 60896-22, and we hold CE, UL, ISO 9001 and ISO 14001. Test reports and declarations are supplied with the shipment documentation, which is what most supplier-audit checklists ask for.

How do I confirm the 15-minute discharge rating before ordering? Send us the model number and the load you actually need to deliver. We will return the discharge curve from our own test data, not a catalogue figure, so you can compare it against what your application needs.

What is the lead time for a first trial order? Sample quantities of any model in the tables above ship by express courier. Volume orders depend on the size — message us the model and annual quantity and you will get a firm answer the same working day.

Talk to an engineer, not a catalogue

If you have a Panasonic part number you are trying to replace, send it over. We will come back with the matching CHISEN model, the full datasheet, the discharge curves and a firm FOB price — normally within one working day.

CHISEN Battery builds across eight production bases with 70 million kVAh of annual capacity, so we can hold stock against your forecast rather than build to order.

If you prefer to talk first, WhatsApp is the fastest route.
