Deep-cycle means a different plate, not a bigger number · review
A 12 V 140 Ah AGM leisure battery quoted at 850 A to EN, described as gas-tight and suitable for indoor use, with a deep-discharge protection named.
The bottom line A 140 Ah AGM whose listing leads with a cranking figure and a unit error, and whose useful content is the gas-tight construction and the polarity. The cycle-life claim compares itself to something it never names.
A 140 Ah AGM sold for motorhomes and movers, with a sheet that needs reading carefully.
850 A to EN is a cold cranking rating: what the battery delivers for seconds at low temperature. It describes starting, not cycling, and this is a battery sold as a solar and leisure battery. The figure is real; it is simply answering a different question.
The fourth bullet gives 353 × 175 × 190 and writes cm. Millimetres are meant — the figures match every other 140 Ah battery on this shelf. It is worth naming because a dimension is the one specification people copy into a tray measurement without re-reading.
Glass fibre mats binding the electrolyte, gas-tight, and the second bullet draws the consequence: suitable for indoor use. That is the practical reason AGM exists in a motorhome, and stating it plainly is useful.
Four times the cycle life. Of what, measured how, to what remaining capacity — none of it is named. No cycle count appears anywhere on the page.

| Capacity | 140 Ah at 12 V, fourth bullet |
|---|---|
| Discharge rate | 850 A to EN, fourth bullet — a cranking figure rather than a cycling one |
| Construction | AGM with glass fibre mats, gas-tight and described as suitable indoors, second bullet |
| Depth of discharge | Absent as a percentage; deep-discharge protection is named in the third bullet |
| Cycle life | Absent as a count — the third bullet claims four times the cycle life of a comparable battery without naming either figure |
| Charging voltage | Nowhere in the listing |
| Terminals | Positive on the right, fourth bullet; no post type or diameter is given |
| Dimensions | Published as 353 × 175 × 190, with the unit written as cm in the listing where mm is meant |
| Amazon reference | B0C28MH4L2 (same reference on 5 Amazon marketplaces) |
| EAN | 5905699500037 |
A cold cranking rating measured to a European standard — how much current the battery delivers briefly at low temperature. It describes starting ability rather than cycling endurance, and on a battery sold as a leisure battery it is an odd headline.
The figures are right and the unit is not: 353 × 175 × 190 in centimetres would be a battery three and a half metres long. Millimetres are meant, and they match the other 140 Ah batteries on this shelf. The error is in the listing, and this page reports it rather than silently correcting it.
