Deep-cycle means a different plate, not a bigger number · review
Electronicx Caravan 12 V 100 Ah AGM, 278 × 175 × 190 mm review
A 12 V 100 Ah sealed AGM leisure battery supplied filled and charged, published with terminal post diameters and polarity, and explicitly stated not to be a starter battery.
The bottom line The easiest battery here to order as a direct replacement, because it publishes the two post diameters and the polarity side. It publishes no cycle count whatsoever, which on a battery sold as deep-cycle is the omission that matters.
A 100 Ah AGM sold for caravans, with a sheet written around fitting rather than around performance.
The measurements that matter for a swap
278 × 175 × 190 mm, 21.5 kg, clamp posts at 19.5 mm positive and 17.9 mm negative, positive on the right. That is enough to check an existing tray, an existing hold-down and an existing pair of clamps without touching anything.
The line that saves a wrong order
The fifth bullet says it is not suitable as a starter battery. Two batteries in this catalogue say so and eighteen do not, and it is the confusion this shelf invites most.
The lines this listing leaves blank
Any cycle count. The third bullet claims the construction allows frequent deep discharge, and nothing anywhere says how many times or to what depth. On a deep-cycle battery, that is the specification.
Nor any charging voltage, absorption figure or float figure — the settings a multi-stage charger needs.
The line about disposal
The last bullet points at local rules for old batteries. It is a small thing and it is the only listing in this catalogue to mention disposal at all.

Questions owners ask about this one
Why publish post diameters?
Because clamp terminals come in sizes, and a clamp that does not close properly on a post is a high-resistance joint that heats under load. Publishing 19.5 mm and 17.9 mm lets an existing clamp be checked before the battery arrives.
What does “supplied filled and charged” mean?
That it arrives ready to use rather than dry. It does not mean fully charged after transit — a battery that has spent weeks in a warehouse will have self-discharged, and a first charge before installation is ordinary practice.
80 Ah at 12 V · AGM, maintenance-free · up to 55 % usable capacity · up to 700 cycles · low internal resistance · sealed and vibration-resistant
A 12 V 80 Ah AGM deep-cycle battery rated for up to 700 cycles, and the only battery in this catalogue whose listing publishes a usable capacity figure.
Best for: A van fit-out where the working capacity, rather than the rated one, is what the budget is built on.
140 Ah at 12 V · AGM with glass fibre mats · 850 A (EN) · deep-discharge protection named · positive on the right · dimensions published with a unit error in the listing
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.
Best for: A motorhome with a mover, where the high current figure is the relevant one.
100 Ah at 12 V · AGM, sealed and maintenance-free · over 600 cycles at 50 % DoD · self-discharge under 3 % a month · −20 °C to +50 °C · M8 terminals · 330 × 172 × 217 mm · 22.5 kg
A 12 V 100 Ah sealed AGM leisure battery rated for over 600 cycles at 50 % depth of discharge, with a published temperature range and a self-discharge figure.
Best for: A garden building or a standby installation where the battery sits for long periods between uses.
