Solar battery Trojan L16-AGM AGM Reliant 370Ah 6V
For off-grid photovoltaic installations and storage systems, the Trojan L16-AGM from the AGM Reliant range stores 370 Ah with AGM technology through daily charge and discharge cycles. It measures 296 × 176 × 417 mm, the format sought by anyone replacing a 370 Ah battery in off-grid PV systems.
- Long life on float and moderate cycling.
- Good tolerance to extreme temperatures.
- Optimised for daily charge and discharge cycles.
- AGM technology: absorbed electrolyte, no spills, can be mounted at an angle.
What the Trojan L16-AGM is for
Designed for off-grid photovoltaic installations and storage systems, the Trojan L16-AGM tolerates extreme temperatures and long periods of low activity. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 52 kg and 5 6 15 terminals.
Dimensions, polarity and mounting
The Trojan L16-AGM is made in the 296 × 176 × 417 mm format and weighs 52 kg. It uses 5 6 15 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.
Why choose Trojan batteries
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.
The Trojan L16-AGM: AGM Reliant range and AGM technology
Within the Trojan catalogue, the AGM Reliant series groups the references designed for this use. The L16-AGM is the 370 Ah model of that family, with the same performance as its siblings in other sizes.
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.
Usage and maintenance tips
Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. Size the installation so as not to discharge the battery more than 50% daily and set the controller to the battery technology.
Warranty and coverage
The Trojan L16-AGM 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 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.

Is the Trojan L16-AGM an AGM battery and what are the benefits of AGM?
Yes. The L16-AGM from Trojan 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 is the Trojan L16-AGM 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 L16-AGM battery last?
Expected lifespan of the Trojan L16-AGM 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 measurements of the L16-AGM model?
Dimensions (length × width × height) are 296×176×417 mm — also written as 296x176x417 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 L16-AGM?
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.
