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 6.04 kg and F6 terminals. ### Will it fit your current battery tray? In terms of format, the Kronobat ES20-12CFT measures 181 × 76 × 167 mm (length × width × height) and weighs 6.04 kg. It uses F6 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. ### Why choose Kronobat batteries With Kronobat we offer an own-brand alternative without compromising on quality: European manufacturing, original-equipment controls and the direct backing of baterias.com for warranty and advice. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty. ### The Kronobat ES20-12CFT: AGM Deep Cycle range and AGM technology The **AGM Deep Cycle** is the Kronobat range the ES20-12CFT belongs to: it shares the same construction and quality criteria with the rest of the series, and varies in capacity and format to suit each vehicle. In an AGM battery the electrolyte is absorbed in glass-fibre separators: there is no free liquid, it cannot spill and it can be mounted at an angle. That construction lowers internal resistance, speeds up recharging and multiplies cycle life compared with a conventional battery. ### Care and maintenance 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. ### Official warranty The Kronobat ES20-12CFT 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. ### Delivery times and returns Order **before 6:00 pm** with stock available and it leaves today: mainland Spain and Portugal receive it in 24-48 working hours, the islands and the rest of the EU in 3 to 5 days. You have **14 days** to return it if it has not been installed, with free collection on the mainland, and shipment tracking by email. ## Frequently asked questions ### Is this battery AGM? What is it for? Yes, it is AGM. In an AGM battery such as the ES20-12CFT, the electrolyte is not free but absorbed in a glass-fibre mat inside a sealed lead-acid battery. Its advantages: more charge/discharge cycles than a conventional battery and better heat tolerance. ### What size is this battery? Measure your device's battery tray first; if the battery exceeds it by even a millimetre, the hold-down clamp may not close. Length × width × height: 181x76x167 mm. Height is measured to the top of the terminals. ## Equivalent batteries - [FULLRIVER HC20](https://baterias.com/gb/battery-fullriver-hc20-12v-20ah-230-cca) - [MK POWERED ES20-12C FT](https://baterias.com/gb/battery-mk-es20-12cft-agm-12v-20ah) ## 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 · 2026-11-13*
