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 31.07 kg. ### Dimensions, polarity and mounting It has external dimensions of 328 Γ— 171 Γ— 247 mm and weighs 31.07 kg. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery. ### Deka: the maker behind the 8G30H Deka (East Penn Manufacturing) is the largest single-site lead battery manufacturer in the United States, with full control of the process from lead recycling to the finished battery. All the Deka batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty. ### Technology inside the Deka 8G30H The 8G30H is one of the Deka 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. ### Care and maintenance GEL batteries need lower charging voltages: always use a charger with a GEL mode so as not to damage the electrolyte. 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 Deka 8G30H 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 Same-day dispatch from our warehouse for in-stock orders placed **before [[ks:cutoff]]**: 24-48 working hours in mainland Spain and Portugal, 3 to 5 days in the islands and the rest of Europe. Returns are accepted for **[[ks:return_days]] days** if the battery has not been used (free collection on the Iberian mainland). You will receive tracking by email. ## Frequently asked questions ### Is the 8G30H model a gel battery? Where is it used? Yes, this model is a GEL battery: sealed lead-acid where the electrolyte is in gel form. It tolerates deep discharges very well and is ideal for cyclic use (solar, motorhomes, electric wheelchairs, motorcycles). Requires a GEL-specific smart charger β€” max charge voltage ~14.1 V (vs 14.4-14.7 V for AGM). Lifespan 6-10 years. ### How do I know if the 8G30H model fits my device? Three ways: 1) enter your number plate in the finder (DGT/DVLA/KBA auto-detect your model and engine); 2) check the "Compatible vehicles" tab on this page, where we list every vehicle verified by our technical team for the 8G30H; 3) if you cannot find your model, message us on WhatsApp with brand, model, engine and year β€” we reply during business hours (Mon–Fri 10:00–13:30 and 16:40–18:00 (Spanish time, CET)). ### How do I change this battery step by step? In most devices it fits in 15-30 minutes with a 10 mm wrench; if the battery is under the seat or in the boot the time can double. See the step-by-step guide on this page. Quick summary: 1) switch off the engine and remove the key; 2) locate the original battery (engine bay, boot or under seat); 3) disconnect the negative (βˆ’) terminal first, then the positive (+); 4) loosen the hold-down clamp and remove the old battery; 5) fit the new one in the same orientation β€” match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (βˆ’). On devices with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile. ### What warranty does the Deka 8G30H battery have? The official manufacturer warranty is 1 year and covers manufacturing defects. It applies to defects such as damaged cells, internal short-circuits or abnormal capacity loss. Wear from misuse (prolonged overcharging, wrong charger or faulty alternator) is not covered. If the battery fails, we replace it at no cost after a technical inspection. ### How long does Deka 8G30H delivery take? In mainland Spain and Portugal it arrives in 24 h if you order before 6:00 pm and the battery is in stock β€” it leaves the same day and arrives the next business day. Afternoon or weekend orders ship the next business day. For Balearics, Canaries and other EU destinations, allow 2-5 days. Shipping cost is calculated in the cart based on destination and service (standard, express, cash on delivery). Tracking number is sent by email + SMS as soon as the parcel ships. ### Can I return the Deka 8G30H battery if it doesn't fit or doesn't work? Yes. You have 14 days from delivery to return it. In mainland Spain and Portugal returns are FREE β€” we cover the return shipping cost via prepaid label. In other EU countries the return shipping cost is the customer's. It must arrive in its original packaging with no signs of installation. If it was defective, the warranty covers replacement even after the 14-day period. ### Where can I buy this battery with full warranty? At baterias.com β€” authorised distributor with real stock, Express 24h delivery in mainland Spain and Portugal if you order before 6:00 pm, and full manufacturer warranty. Shipping cost is calculated in the cart based on destination and chosen service (standard, express, cash on delivery). Secure payment by card, Bizum, PayPal or bank transfer. If you choose at-home installation, our technician will take the used battery and dispose of it through an authorised collection point. ### How many years does this battery last? Expected lifespan of the Deka 8G30H is 6 to 10 years in cyclic use (marine, caravan, solar) with controlled discharges. In cold regions it drops slightly due to cold-start stress; in very hot regions it also drops because of electrolyte evaporation. To extend its life: avoid deep discharges (headlights on with engine off), have the alternator checked yearly, and keep the battery clean and properly secured. ### What are the dimensions of the Deka 8G30H battery? Dimensions (length Γ— width Γ— height) are 328Γ—171Γ—248 mm β€” also written as 328x171x248 mm β€” following the European DIN standard. Always measure the space in your device before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals. ### How much does the Deka 8G30H battery weigh? It weighs 31,1 kg. Most of the weight is lead. If you plan to fit it yourself, use gloves and a carrying strap (AGM batteries are slightly heavier than conventional due to the absorbent glass-mat fibre). ### Which batteries are equivalent to the Deka 8G30H? Directly interchangeable batteries (same dimensions, same polarity, same Ah and CCA) are the OEM equivalents from leading brands: Bosch, Tudor, Exide and, depending on the model, Banner or Yuasa. Exact equivalence depends on technology β€” an EFB cannot be replaced with a conventional battery in Start-Stop devices. See the "Equivalents" section to view recommended options at the same performance level. ### Which is better: Deka 8G30H or an alternative from another brand? This battery and its equivalents from Bosch, Tudor or Exide are technically comparable: same dimensions, same voltage and same capacity. The differences are warranty (Varta and Bosch: 2 years; Tudor and Exide: 2 years on the equivalent line), manufacturing plant (Varta and Bosch share origin in the Clarios Group; Tudor and Exide belong to Exide Technologies) and price. For private use any of these brands will give 4-6 years of life. Compare them in the "Equivalents" section. ### What do users say about the Deka 8G30H battery?
