6*V* Voltage
210*Ah* Capacity
36*kg* Weight

For off-grid photovoltaic installations and storage systems, the **Trojan TE35-GEL** stores **210 Ah** with GEL technology through daily charge and discharge cycles. Its 245 × 191 × 271 mm make it the exact replacement for the 210 Ah battery fitted as standard to many off-grid PV systems.
- Compatible with common MPPT and PWM controllers.
- Maintenance-free in off-grid installations.
- Low self-discharge during the darker months.
- GEL: excellent resistance to deep discharge and long cycle life.

### What the Trojan TE35-GEL is for

The Trojan TE35-GEL is designed for off-grid photovoltaic installations and storage systems. Size the capacity so as not to discharge more than 50% daily and you will greatly extend its life. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 36 kg and 8 terminals.

### Technology inside the Trojan TE35-GEL

The TE35-GEL is one of the Trojan references for this type of use; it shares the same manufacturing and quality-control criteria as the rest of the brand's catalogue.
A GEL battery is the choice when cycle resistance and safety matter most: no gases, no liquid and thousands of partial discharges in its lifetime.

### Size, terminals and hold-down of the Trojan TE35-GEL

It has external dimensions of 245 × 191 × 271 mm and weighs 36 kg. It uses 8 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.

### What Trojan does differently

Founded in 1925 in California, Trojan invented the golf cart battery and remains the standard in deep-discharge applications that demand thousands of cycles. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.

### Care and maintenance

Size the installation so as not to discharge the battery more than 50% daily and set the controller to the battery technology. In the darker months, check the voltage periodically and avoid full discharges.

### Manufacturer's warranty

The Trojan TE35-GEL 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.

### When you get it and how to return it

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 the Trojan TE35-GEL a GEL battery? What is GEL used for?

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 — max charge voltage ~14.1 V (vs 14.4-14.7 V for AGM). Lifespan 6-10 years.

### How is the Trojan TE35-GEL battery installed in the vehicle?

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 our blog. 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 Trojan TE35-GEL battery last?

Expected lifespan of the Trojan TE35-GEL 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 Trojan TE35-GEL battery?

Dimensions (length × width × height) are 245×191×271 mm — also written as 245x191x271 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 Trojan TE35-GEL?

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.
