It uses F4 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. ### What the Sonnenschein GF12063YO is for The Sonnenschein GF12063YO is designed for power wheelchairs, mobility scooters and light electric vehicles. Wheelchairs and scooters normally use two identical batteries in series: replace them together. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 25 kg and F4 terminals. ### Technology inside the Sonnenschein GF12063YO The GF12063YO is one of the Sonnenschein references for this type of use; it shares the same manufacturing and quality-control criteria as the rest of the brand's catalogue. 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. ### Why choose Sonnenschein batteries Sonnenschein batteries with dryfit® technology have equipped power wheelchairs, cleaning machines and industrial vehicles for decades thanks to their reliability and cycle life. All the Sonnenschein batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty. ### Warranty and coverage The Sonnenschein GF12063YO comes with the **manufacturer's official warranty** against manufacturing defects. If it fails through a defect within the warranty period, we replace it at no cost to you. ### How to make it last longer Recharge the wheelchair or scooter after each use and do not leave it discharged for days: lead sulphates and loses capacity. Use the original charger or one compatible with the battery technology (AGM/GEL) and always replace both batteries in the set together. ### When you get it and how to return it Orders placed **before 6:00 pm** with the battery in stock ship the same day.

Yes: in the GF12063YO the electrolyte is gelled. It is a sealed lead-acid GEL battery. Deep discharges are its strong point, so it suits cyclic use: solar, motorhomes, electric wheelchairs or motorcycles. Charge it only with a GEL-specific smart charger; its voltage limit is below that of an AGM. ### What are the dimensions of the Sonnenschein GF12063YO battery? Its dimensions are 260×171×210 mm, also written 260x171x210 mm; the height already includes the terminals. Check the room available in your device, because a single millimetre too much can stop the clamp from closing. ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team — automotive battery specialists since 2012. → https://baterias.com/gb/technical-team --- *baterias.com — Automotive batteries · 2026-11-07*
