Leoch PLX12-600FT Pure Lead High Rate Battery
Leoch PLX12-600FT Pure Lead High Rate Battery
Leoch PLX12-600FT Battery - 12V 150Ah Pure Lead High Rate AGM, Front Terminal
Warranty
What Stays the Same Across the Front-Terminal 150 Ah Slot
- 150 Ah - the listed capacity of the PLX12-600FT and the published 10-hour capacity of the current PLX12-620FT(A).
- 620 watts per cell at 15 minutes - the rating Leoch publishes for the PLX12-620FT(A) to 1.67 volts per cell; the PLX12-600FT listing carried a 1,400 amp maximum discharge figure and no 15-minute rating.
- Front terminals in a 125 mm wide case - four blocks across a 23-inch shelf with the posts facing the aisle, the layout the FT suffix exists for.
- About 105 to 107 lbs per block - 104.7 lbs as listed for the PLX12-600FT, 48.5 kg (106.9 lbs) published for the PLX12-620FT(A).
- M8 as listed, M6 standard on the current part - the PLX12-620FT(A) ships with an M6 insert and M8 as an option, so the terminal hardware is specified on the quote.

Where This Battery Is Used
- Telecom power plants on 23-inch racks - the -48 volt strings where a 22-inch front-terminal block is the standard shelf fill and access from the aisle is the reason for the format.
- Outdoor and unconditioned cabinets - cell sites and remote huts, where the PLX range's -40°C to 65°C discharge rating is the trait that matters most.
- Rack-mount UPS battery cabinets - modular UPS systems built around the 559 by 125 mm front-terminal footprint that Leoch shares across the PLX12-450FT(A) to PLX12-730FT.

Frequently Asked Questions
What warranty applies, and is the 15-year figure part of it?
The warranty is Leoch's 60 months, full replacement, on the PLX line, and it applies whether the block that ships is labeled PLX12-600FT or PLX12-620FT(A). The 15 years is design life, Leoch's estimate of float service at 25°C from the PLX range summary, and it is not a replacement commitment. The quote names the shipping part number and the warranty document that governs it, and the term is confirmed in writing there.
Is the PLX12-600FT still made?
Leoch's current published PLX range does not list it. The range summary dated December 2025 shows the front-terminal blocks as PLX12-260FT(A), 400FT(A), 450FT(A), 620FT(A), 700FT(A) and 730FT, and the 150 Ah position in the 559 by 125 mm case is the PLX12-620FT(A). This page keeps the PLX12-600FT part number because plants were built on it and buyers search for it; whether a block labeled PLX12-600FT can still be sourced, or the PLX12-620FT(A) ships in its place, is settled on the quote with availability checked on the day.
If the PLX12-620FT(A) ships instead, what changes on the shelf?
Very little physically. The case is 559 by 125 by 277 mm, which is the same footprint and within a fraction of an inch of the listed height, and the weight goes from about 104.7 to 106.9 lbs. The rating is published as 620 watts per cell over 15 minutes; the PLX12-600FT listing never carried a 15-minute figure to compare against. The terminal is the item to check: the current part comes with an M6 insert as standard and M8 as an option, and the listing for the PLX12-600FT shows M8. State the hardware your connectors need and the quote specifies it.
Can I put one new block into a string of older PLX12-600FT?
Not without a review. A new block in an aged string ages to the string, and in a series string the weakest block sets the runtime, so the replacement rarely delivers what its own datasheet says. If one block has failed early inside the warranty period, the claim path is the right route. If the string is several years old, the honest answer is usually to plan the whole string and keep the good survivors as spares. A specialist can look at the string's float readings and the install date and tell you which case you are in before anything is ordered.
Send the quantity, your delivery ZIP and a photo of one block's label. A specialist checks what can be sourced under that number, confirms the PLX12-620FT(A) fit if that is what ships, and quotes the set with lead time and freight in writing.
