Designed for power wheelchairs, mobility scooters and light electric vehicles, the Fullriver HC70 from the HC range offers 70 Ah of deep-cycle capacity with AGM technology. It replaces the original battery without adaptation in power wheelchairs and mobility scooters with a 351 × 167 × 179 mm format: same 70 Ah capacity.
- AGM technology: absorbed electrolyte, no spills, can be mounted at an angle.
- Designed to be discharged and recharged daily without losing capacity.
- Thousands of useful cycles over its lifetime.
- Standard replacement format for wheelchairs and scooters.
What the Fullriver HC70 is for
The Fullriver HC70 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 11.50 kg and M8 terminals.
Size, terminals and hold-down of the Fullriver HC70
It has external dimensions of 351 × 167 × 179 mm and weighs 11.50 kg. It uses M8 terminals, the system that anchors and connects it in the vehicle. Before replacing it, measure your current battery tray: if all three dimensions and the terminal positions match, the swap is direct and needs no adapters.
The Fullriver HC70: HC range and AGM technology
The HC is the Fullriver range the HC70 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.
What Fullriver does differently
With its own plants and a catalogue focused on high-performance AGM, Fullriver is a familiar brand in power wheelchairs, boats and photovoltaic systems that need thousands of cycles. We guarantee that every Fullriver arrives new, charged and with the manufacturer's full warranty.
Warranty and coverage
The Fullriver HC70 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.
Usage and maintenance tips
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
Same-day dispatch from our warehouse for in-stock orders placed before 6:00 pm: 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 14 days if the battery has not been used (free collection on the Iberian mainland). You will receive tracking by email.

How to change the battery
Guide to replace a cyclic battery (12V 4-30Ah) for UPS, mobility scooter, alarm or backup device. Estimated time 10-15 minutes. Important: discharge residual voltage before handling.
Step 1. Power off and unplug the device
Unplug the device (UPS, scooter, alarm) and leave it off for at least 30 seconds to discharge residual capacitor voltage. Work on an insulating surface.
Step 2. Locate the battery compartment
Usually under the seat (mobility scooter/wheelchair), in the rear module of the UPS, or behind a side panel with screws. Check the device manual for unusual models.
Step 3. Disconnect the negative (−) first
With insulated gloves, remove the negative (−) cable first. Some UPS have protection fuses — note their position before removing.
Step 4. Disconnect the positive (+) terminal
Repeat with the positive cable (red, marked +). Important: never let a terminal touch metal of the car while the other is still connected.
Step 5. Remove the old battery
Typical weight 1-15 kg depending on capacity. Many cyclic batteries are AGM/GEL — keep them upright. Do NOT invert the battery: even sealed, residue may exist.
Step 6. Fit the new battery
Same orientation and type (AGM, GEL or flooded). Polarity must match the device, not a chassis (this is not a car). Make sure terminals do not touch metal parts of the compartment.
Step 7. Connect the positive (+) first
On cyclic devices the order is reversed compared to cars: positive (+) first, negative (−) afterwards. Tighten without forcing — the plastic terminal housing of cyclic batteries damages easily.
Step 8. Initial charge before first use
Cyclic batteries ship at 60-80%. Before first use, connect the device charger for 8-12 hours (or use an AGM/GEL smart charger if available). This avoids short cycles and extends lifespan.
Frequently asked questions
Is the Fullriver HC70 an AGM battery and what are the benefits of AGM?
Yes. The HC70 from Fullriver uses AGM (Absorbent Glass Mat) technology: a sealed lead-acid battery where the electrolyte is absorbed in a glass-fibre mat. It withstands more charge/discharge cycles than a conventional one, handles heat better and is the required technology for devices with advanced Start-Stop and regenerative braking. Expected lifespan: 5-8 years under normal conditions.
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 (−) 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 — match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (−). On devices with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile.
How long does the Fullriver HC70 battery last?
Expected lifespan of the Fullriver HC70 is 5 to 8 years in mild-climate device use with Start-Stop. 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 Fullriver HC70 battery?
Dimensions (length × width × height) are 351×167×179 mm — also written as 351x167x179 mm — 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.
Which batteries are equivalent to the Fullriver HC70?
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 — 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.
