The Trojan SIND 04 1685 with conventional lead-acid technology stores 1,293 Ah at 4 V for off-grid photovoltaic installations and storage systems. It replaces the original battery without adaptation in off-grid PV systems with a 567 × 261 × 610 mm format: same 1,293 Ah capacity.
- Good tolerance to extreme temperatures.
- Long life on float and moderate cycling.
- Conventional lead-acid: the most proven and economical technology.
- Optimised for daily charge and discharge cycles.
What the Trojan SIND 04 1685 is for
Designed for off-grid photovoltaic installations and storage systems, the Trojan SIND 04 1685 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 167 kg.
Dimensions, polarity and mounting
The Trojan SIND 04 1685 is made in the 567 × 261 × 610 mm format and weighs 167 kg. For a direct replacement, the current battery tray must accept these dimensions and the same terminal layout; otherwise adapters will be needed or the hold-down will change.
The Trojan SIND 04 1685: Industrial Energia Renovable - Smart Car range and conventional lead-acid technology
The Industrial Energia Renovable - Smart Car is the Trojan range the SIND 04 1685 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.
The conventional lead-acid battery remains the most widespread technology thanks to its balance of capacity, cranking current and price. Well maintained and kept charged, it offers years of reliable service in vehicles without Start-Stop.
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. We guarantee that every Trojan arrives new, charged and with the manufacturer's full warranty.
Manufacturer's warranty
The Trojan SIND 04 1685 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
In the darker months, check the voltage periodically and avoid full discharges. Size the installation so as not to discharge the battery more than 50% daily and set the controller to the battery technology.
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
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 Trojan SIND 04 1685 battery last?
Expected lifespan of the Trojan SIND 04 1685 is 4 to 6 years in regular device use without 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 Trojan SIND 04 1685 battery?
Dimensions (length × width × height) are 567×261×610 mm — also written as 567x261x610 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 SIND 04 1685?
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.
