- Designed for solar systemsoptimised for daily charge/discharge cycles
- Handles extreme temperaturesin technical rooms or outdoor installs
- Minimal self-dischargewhen left idle over winter or holidays

Solar battery Trojan 6V-GEL 189Ah 6V
The 6 V, 189 Ah Trojan 6V-GEL solar battery with GEL technology is designed for off-grid photovoltaic installations and storage systems. It replaces the original battery without adaptation in off-grid PV systems with a 260 × 181 × 275 mm format: same 189 Ah capacity.
- GEL technology: gelled electrolyte, fully sealed and maintenance-free.
- Optimised for daily charge and discharge cycles.
- Good tolerance to extreme temperatures.
- Long life on float and moderate cycling.
Dimensions, polarity and mounting
It has external dimensions of 260 × 181 × 275 mm and weighs 31 kg. It uses 6 terminals, the system that anchors and connects it in the vehicle. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery.
What the Trojan 6V-GEL is for
The Trojan 6V-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 31 kg and 6 terminals.
Technology inside the Trojan 6V-GEL
Trojan builds the 6V-GEL to the same standards as the rest of its catalogue; what changes between references is capacity, format and terminal position.
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.
What Trojan does differently
Trojan Battery is the world reference in deep-cycle batteries: golf carts, cleaning machines, aerial platforms and solar systems rely on its T2 technology and longevity. All the Trojan batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.
Manufacturer's warranty
The Trojan 6V-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.
How to make it last longer
GEL batteries need lower charging voltages: always use a charger with a GEL mode so as not to damage the electrolyte. In the darker months, check the voltage periodically and avoid full discharges.
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 6V-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 do I fit the 6V-GEL model in my device?
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.
What is the service life of the 6V-GEL model?
Expected lifespan of the Trojan 6V-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 measurements of the 6V-GEL model?
Dimensions (length × width × height) are 260×181×275 mm — also written as 260x181x275 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.
What are the equivalents of the 6V-GEL model?
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.
