## Description

## The Ritar HR12-104W at a glance

The Ritar HR12-104W is a high-rate battery for UPS: optimised to deliver a lot of power for a few minutes, the typical regime of a mains outage. Its key figure is watts per cell over 15 minutes, not amp-hours.
The HR12-104W belongs to the Ritar RITAR HR range. [See all Ritar batteries](https://bateriasonline.es/en/ritar-batteries)

## What it means that the HR12-104W is AGM

The HR12-104W 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.

## Ritar HR12-104W vs HR12-96W and HR12-125W

The real differences between the HR12-104W and the closest Ritar models:

| Model | Capacity | Dimensions (mm) | Weight |
