    Modern vehicles equipped with start-stop systems place considerable cyclic demand on their batteries, requiring a power source capable of repeated deep discharge and rapid recharge cycles. The Bosch S5A11 AGM Car Battery meets this challenge directly, delivering 12V, 80Ah capacity and 800A CCA in a unit engineered specifically for start-stop and energy recovery applications. Bosch manufactures the S5A range using Absorbent Glass Mat technology, in which the electrolyte is fully absorbed into micro glass fibre mats rather than held in free liquid form. This construction eliminates acid stratification, reduces internal resistance, and enables the battery to accept high charge currents from regenerative braking systems. The result is a power source that sustains reliable cranking performance and supports the sustained electrical loads placed on the vehicle during engine-off stop phases. The S5A11 measures 315mm x- 175mm - 190mm (L x- W x- H) and weighs 22.76kg. It uses a Type 1 terminal configuration with standard polarity (terminal arrangement code 0) and is secured via B13 hold-down. It carries the BCI/DIN cross-reference designation 115AGM, making it a direct replacement for vehicles specifying that type. Always verify fitment against your vehicle manufacturer's specification before ordering. The S5A11 is one of several capacities within the Bosch S5A AGM range. Related variants include the S5A08, S5A13, and S5A15, alongside the LA008, LA009, LA010, and LA011 from the associated leisure and auxiliary range. This battery is supplied with a 3-year warranty. . The Bosch S5 A battery with AGM technology provides sufficient energy for frequent stops and starts and reliably supplies the electronic consumers during the stop phase. AGM technology (Absorbent Glass Mat): acid bound in micro glass fibre mats allows higher energy masses to pass through. Longer life and up to 4 times higher cycle stability compared to conventional starter batteries. Constant power even during short trips, stop-and-go traffic or high consumption when stationary. Excellent charge absorption and starting power with a high number of electrical consumers. Absolutely maintenance-free and leak-proof.

Frequently Asked Questions

Q1- What is the voltage and capacity of the Bosch S5A11?
ANS- The Bosch S5A11 is a 12V battery with a rated capacity of 80Ah (C20) and a Cold Cranking Amp (CCA EN) rating of 800A.

Q2- Is the Bosch S5A11 compatible with start-stop vehicles?
ANS- Yes. The S5A11 is purpose-built for vehicles fitted with start-stop systems and supports energy recovery via regenerative braking. AGM technology enables it to handle the frequent charge and discharge cycles these systems demand.

Q3- What are the physical dimensions of the S5A11?
ANS- The battery measures 315mm in length, 175mm in width, and 190mm in height including the terminals. It weighs 22.76kg.

Q4- What terminal type and polarity does the S5A11 use?
ANS- The S5A11 uses a Type 1 terminal configuration with standard polarity (polarity code 0, positive terminal on the left when viewed from the front). The hold-down type is B13.

Q5- What cross-reference number does the Bosch S5A11 correspond to?
ANS- The S5A11 cross-references to the 115AGM battery type designation. Always confirm fitment against your vehicle's handbook or manufacturer specification before purchase.

Q6- What is AGM technology and why does it matter for start-stop vehicles?
ANS- AGM stands for Absorbent Glass Mat. The electrolyte is held within glass fibre mats rather than in free liquid form, which eliminates acid stratification, lowers internal resistance, and allows the battery to accept high charge currents from regenerative braking systems. This makes AGM batteries significantly more durable under the cyclic loading of start-stop operation than conventional flooded batteries.

Q7- Can the Bosch S5A11 replace a standard lead-acid battery in a non-start-stop vehicle?
ANS- An AGM battery can function in a non-start-stop vehicle, but you should confirm that the vehicle's charging system is compatible with AGM technology. Some older vehicles may require a charging voltage adjustment. Consult your vehicle handbook or a qualified technician if in doubt.

Q8- What warranty is provided with the Bosch S5A11?
ANS- The S5A11 is backed by a 3-year warranty from the date of purchase.
