Varta G7 Dynamic SLI · Car battery 95Ah 830A

Allow 15-30 minutes and a 10 mm spanner. If the car keeps its battery in the boot or under a seat, it can take up to twice as long. Before you start, check the car handbook: the manufacturer's procedure always comes first. Our full step-by-step guide is on the blog. The right order: engine off and key out; disconnect the negative (−) first, then the positive (+); release the hold-down clamp, lift out the old battery and seat the new one in the same position (positive on the right), keeping the polarity; reconnect the positive (+) first and the negative (−) last.

Estimated lifespan of the Varta G7: 4 to 6 years in regular car use without Start-Stop. Treat it as an approximate guide, as every case is different. 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 car and Start-Stop also count.

Its dimensions are 306×173×225 mm, also written 306x173x225 mm; the height already includes the terminals. Check the room available in your car, because a single millimetre too much can stop the clamp from closing.

The G7 has the positive on the right: that is its polarity. It must match your current battery: reversed polarity means lengthening cables or reconfiguring the system, with a risk of short circuit. Face the battery with its terminals nearest you and see which side the positive post (+, red ring) is on.

Parts catalogues list it under ETN 595 404 083 (in full, 5954040833132); the manufacturer's reference is G7 and its EAN-13 is 4016987167700. It belongs to the Varta Dynamic SLI range. Any of the three works for getting a quote or comparing prices without mix-ups.

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)). Always cross-check with what the car manufacturer states in the owner's handbook. The compatibility list for the G7 runs to 723 verified vehicle versions.

Not just any technology will do: an EFB cannot be replaced with a conventional battery in Start-Stop cars. The "Equivalents" section further down lists the recommended alternatives. Interchangeable means the same dimensions, same polarity, same Ah and same CCA; for the G7, 95 Ah (830 A cranking).

A technology step up: EFB for cars with basic Start-Stop, in the same tray as the G7. Compared with the G7 it has 30 A of cold cranking less. It costs 8,90 € more. Pays off in cars with lots of stops and starts; for normal use without Start-Stop, the G7 is enough.

Same case and same fitting as the G7, from Tudor. Compared with the G7 it has 70 A of cold cranking less. It costs 3,80 € more. If you want to save or the G7 is out of stock, it is the safe alternative: same dimensions, same polarity and official warranty.
