## Description

## The Trojan SAES 12 135 at a glance

The Trojan SAES 12 135 is a deep-cycle battery for off-grid solar systems: it stores the day's energy for use at night and withstands years of charge and discharge cycles. Its capacity is rated at 20 hours (C20); at slower discharge rates the usable capacity is higher.
The SAES 12 135 belongs to the Trojan TROJAN Solar AES range. [More Trojan batteries](https://bateriasonline.es/en/trojan-batteries)

## AGM technology in the SAES 12 135

The SAES 12 135 is AGM: the electrolyte is absorbed in glass fibre mats, so it is sealed and spill-proof. It withstands many more cycles than a conventional lead battery, at the cost of being more sensitive to overcharging.

## Frequently asked questions about the Trojan SAES 12 135

### SAES 12 135 or SAGM 12 135: which one suits me?

Compared with the SAES 12 135, the Trojan SAGM 12 135 has 1 Ah more. With 135 Ah, the SAGM 12 135 runs longer between charges than the SAES 12 135 (134 Ah). Both measure 329 × 179 × 278 mm, so they fit the same tray.

### How much does the Trojan SAES 12 135 weigh?

39 kg, with 134 Ah of capacity. For reference, the Trojan SAGM 12 135 (135 Ah) weighs 38 kg.

### Which battery is equivalent to the Trojan SAES 12 135?

Only other AGM batteries with its dimensions and polarity: Trojan SAGM 12 135 and Trojan T1275-AGM. Neither an EFB nor a conventional battery replaces the SAES 12 135.

### Which charger does the Trojan SAES 12 135 need?

A charger with an AGM mode that limits voltage to about 14.4-14.7 V. Never an old unregulated charger: overcharging dries out an AGM beyond repair.
