HOPPECKE grid Xtreme VR 121500 FT Battery

Name: HOPPECKE grid Xtreme VR 121500 FT Battery | Seven Star LLC
Brand: HOPPECKE
SKU: grid Xtreme VR 121500 FT

grid | Xtreme VR 121500 FT is the 12 V front-terminal block of the HOPPECKE grid | Xtreme VR green series, a pure lead AGM battery with an ABS-PC case. The green series data sheet lists 150 Ah at C10, 154 Ah at C8 and a footprint of 563 x 110 mm with 307 mm height, weighing about 48.7 kg.

A front-terminal pure lead block for cabinets with front access only

FT means real front terminals: cables and links are fitted on the front face, no extra connectors are needed, and the 110 mm width keeps the footprint narrow. The data sheet stresses ease of installation and maintenance. The 121500 FT is the middle size of the six FT types, between 121000 FT (94 Ah) and 122000 FT (196 Ah).

The green series flyer sets it beside the standard (pure) Xtreme VR and shows what changes: a front-terminal-only design, a narrower temperature window and a shorter life at 30 °C. Both use thin-plate pure lead technology with ESS electrolyte-stratification protection for frequent cycling.

Features stated in the green series data sheet

Pure lead grid electrodes (99.98 percent purity) with microporous glass fibre separators and ESS technology.
Operating range -35 °C to +50 °C, 15 years design life, Very Long Life class (over 12 years) per Eurobat Guide 2015.
Designed to be compliant with IEC 60896-21/22; UL recognized; UL94 V-0 halogen-free ABS-PC case.
Storage time up to 2 years; no refilling of distilled water; classified non-spillable and non-hazardous for ADR/RID, IMDG and IATA transport.

Selecting between the green series FT types and the top-terminal blocks

The same data sheet lists FT types 121000 FT 19 inch (94 Ah, 404 x 110 x 264 mm), 121000 FT 23 inch (103 Ah), 121500 FT (150 Ah), 121700 FT (165 Ah), 121900 FT (185 Ah, 563 x 125 x 307 mm) and 122000 FT (196 Ah, 60.0 kg), plus top-terminal blocks 122900 to 126000 (86 to 176 Ah).

Compare the C1 and C3 figures when the string must hold a load for minutes only. Where the room is hot or runtime must last, the standard series offers the wider range, so confirm the exact code and terminal version before ordering.

Installation and charging points from the manual

Check open-circuit voltage before connection: 12.78 V to 13.08 V per block at 20 °C, with no more than 0.05 V between blocks. Tighten terminal screws to 15 Nm plus or minus 1 Nm and use isolated connectors.

Float at 2.30 V per cell plus or minus 1 percent. New systems show wider voltage spreads that normally settle after about 6 months of standby parallel operation, so an equalizing charge is not the first response. Commissioning uses at most 2.4 V per cell and 20 A per 100 Ah.

Where front-terminal AGM blocks fit in the Gulf

The product page lists UPS and data centre, fossil power plants, telecommunication, oil and gas, emergency lighting and railway infrastructure among grid applications. General engineering note: in Gulf telecom shelters and compact UPS cabinets, front access matters wherever cabinet rows leave no top or rear access.

Frequently asked questions

What does FT mean in 121500 FT?

FT stands for front terminals: the poles are on the front face so connections need no additional connectors.

What capacity does 121500 FT have?

The green series data sheet gives 150 Ah at C10 and 154 Ah at C8, with 140 Ah at C3 and 118 Ah at C1.

How wide is the operating range?

-35 °C to +50 °C for the green series, narrower than -40 °C to +55 °C for the standard pure series.

What float voltage should be set?

2.3 volts per cell at 20 °C, plus or minus 1 percent, and 2.288 volts at 25 °C.
