GF12051Y2 vs Sonnenschein GF12040Y
The Sonnenschein GF12051Y2 offers 56 Ah and 0 A cold cranking in a 278 × 175 × 190 mm case.

What the Sonnenschein GF12051Y2 is for
The Sonnenschein GF12051Y2 is the usual replacement in power wheelchairs, mobility scooters and light electric vehicles. Recharge after each use and avoid leaving it discharged for days. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 20.80 kg and A-Terminal terminals.
Technology inside the Sonnenschein GF12051Y2
Sonnenschein builds the GF12051Y2 to the same standards as the rest of its catalogue; what changes between references is capacity, format and terminal position.
GEL technology fixes the acid in a solid gel. That removes maintenance and leaks and gives very long cycle life, in exchange for slightly slower recharging and lower peak current than an AGM.
Dimensions, polarity and mounting
It has external dimensions of 278 × 175 × 190 mm and weighs 20.80 kg. It uses A-Terminal terminals, the system that anchors and connects it in the vehicle. For a direct replacement, the current battery tray must accept these dimensions and the same terminal layout; otherwise adapters will be needed or the hold-down will change.

At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.
How to make it last longer
Use the original charger or one compatible with the battery technology (AGM/GEL) and always replace both batteries in the set together. GEL batteries need lower charging voltages: always use a charger with a GEL mode so as not to damage the electrolyte.

Frequently asked questions
Is the GF12051Y2 model a gel battery? Where is it used?
Yes, this model is a GEL battery: sealed lead-acid with the electrolyte in gel form. It tolerates deep discharges very well and is ideal for cyclic use (solar, motorhomes, electric wheelchairs, motorcycles). It needs a GEL-specific smart charger: its maximum charge voltage is lower than that of an AGM.
What are the dimensions of the Sonnenschein GF12051Y2 battery?
Length × width × height: 278x175x190 mm (L3 case). Height is measured to the top of the terminals. Measure your device's battery tray first; if the battery exceeds it by even a millimetre, the hold-down clamp may not close.
