Tudor TE1853 Strong Pro · Truck battery 185Ah 1100A EFB

Yes: the TE1853 (185 Ah) is an EFB, an evolution of the flooded lead-acid battery with additives that strengthen the plates. It withstands more cycles than a conventional battery but fewer than an AGM, and it is fitted to trucks with basic Start-Stop, without regenerative braking. It is more affordable than an equivalent AGM.

Yes: being EFB, the Tudor TE1853 is designed for Start-Stop trucks. EFB batteries cover basic Start-Stop (no regenerative braking). Basic Start-Stop: EFB. Start-Stop with regenerative braking: AGM, which withstands more cycles. Check the handbook for the technology the truck manufacturer requires. Once fitted it is ready to go; registering it via OBD, advisable on most modern models, lets the alternator charge with the optimum profile.

Most lorries, buses and tractors run on 24 V with two 12 V batteries connected in series. Always replace both at the same time and with the same model: if one is new and the other old, they become unbalanced and both last less.

As a guide, you can expect the Tudor TE1853 to last 5 to 7 years in lorry use, even with high power draw while parked, although the real figure may be higher or lower. Actual lifespan varies with climate (cold starts, heat evaporating the electrolyte), with usage and short journeys, with the condition of the alternator and charging system, with power draw while parked and with maintenance; the type of truck and Start-Stop also count.

Its dimensions are 513×223×223 mm, also written 513x223x223 mm; the height already includes the terminals. Check the room available in your truck, because a single millimetre too much can stop the clamp from closing.

On the Tudor TE1853, the polarity is positive on the left. To check, stand the battery in front of you with the terminals nearest you: the positive (+) is the one with the red ring. A change of polarity from the original means longer cables or a reconfigured system and can cause a short circuit: check it before ordering.

The quickest way is to enter your number plate in the finder: DGT/DVLA/KBA detect model and engine. You can also look at the "Compatible vehicles" tab, verified by our technical team, or send us make, model, engine and year on WhatsApp; we answer during business hours (Mon–Fri 10:00–13:30 and 16:30–18:00 (Spanish time, CET)). According to our data, 141 verified vehicle versions are compatible with the TE1853. Always cross-check with what the truck manufacturer states in the owner's handbook.

Not just any technology will do: an EFB cannot be replaced with a conventional battery in Start-Stop trucks. The "Equivalents" section further down lists the recommended alternatives. Interchangeable means the same dimensions, same polarity, same Ah and same CCA; for the TE1853, 185 Ah (1100 A cranking).

Rule of thumb: truck with an EFB from new, EFB (AGM is an optional, marginal upgrade); truck with an AGM from new, AGM. It is still flooded lead-acid, but an EFB reinforces the plates with carbon and polyethylene and uses thicker grids. That gives it more cycles than a conventional battery and deeper discharge tolerance, though less than an AGM. Many basic Start-Stop systems (no regenerative braking) come with it from the factory, such as Renault Energy TCe, Peugeot/Citroën PureTech, Fiat MultiAir, Hyundai/Kia ISG and Ford EcoBoost.

The alternator detects the new battery and adapts the charge automatically, so on most trucks it is not compulsory. Even so, it is advisable to register it via OBD so charging is optimum from the first minute and the battery lasts longer, particularly on BMW, Mercedes, Audi, Volvo or Land Rover, with more sophisticated BMS. Any workshop with an OBD scanner does it in a few minutes; DIY, with VCDS or Carista (VAG group), Bimmercode (BMW) or iCarsoft. Even if you do not register the Tudor TE1853, the truck will start correctly; the profile adjusts within a few days.
