Deep-cycle means a different plate, not a bigger number · review
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.
The bottom line The best-documented AGM here for a battery that will spend time idle: a self-discharge rate, a temperature range at both ends, and full physical details. It publishes no charging voltage, which is the number a charger needs.
A 100 Ah sealed AGM leisure battery, specified for standby as much as for cycling.
Self-discharge under 3 % a month. On a battery that spends the winter in a shed or a boat, that figure decides how often it must be checked and whether it survives until spring. Lead-acid left discharged sulphates, and the damage is not undone by charging it later.
600 cycles at 50 % discharge. That pairing is the conventional lead-acid arrangement: roughly half the rated capacity is the everyday working range, and the cycle count assumes it. Reading 100 Ah as 100 Ah of usable energy is the commonest error on this shelf.
330 × 172 × 217 mm, 22.5 kg, M8 terminals, described as shock and vibration resistant. Everything the tray and the hold-down need.
No charging voltage, and no absorption or float figures. Those are the settings a multi-stage charger has to be given, and this listing leaves them to the charger’s defaults.

Because a lead-acid battery left to discharge sulphates, and sulphation is not reversible by ordinary charging. Under 3 % a month tells you roughly how often a battery in storage needs attention — which is the question that decides whether it survives a winter unused.
That the count assumes half the capacity is used each time. Going deeper reduces it. It also means only about half of the 100 Ah is intended for everyday use, which is the conventional working depth for this construction.
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.
