## Description

## Where the Long U1-36HE fits

The Long U1-36HE is a deep-cycle battery for electric wheelchairs: sealed, maintenance-free and built to discharge and recharge every day without losing capacity. It is fitted as a 12 V pair and takes hundreds of daily cycles, something a starter battery could not handle.
The U1-36HE belongs to the Long U1 Series range. [More Long batteries](https://bateriasonline.es/en/long-batteries)

## Equivalents and alternatives to the Long U1-36HE

As the U1-36HE is an AGM battery, we only list other AGM batteries with its dimensions and polarity: neither an EFB nor a conventional battery can replace it.

| Model | Technology | Capacity | Dimensions (mm) |
|---|---|---|---|
| MK Battery MU-1 SLD M-2 | AGM | 35 Ah | 197 × 131 × 180 |
| Kronobat ES34-12 | AGM | 34 Ah | 197 × 131 × 180 |
| MK Battery ES33-12 | AGM | 35 Ah | 196.1 × 130 × 180.1 |
| MK Battery MU-1 SLD M | AGM | 35 Ah | 196.1 × 130 × 180.1 |
| Ritar RA12-33 | AGM | 35 Ah | 195 × 130 × 180 |

## Long U1-36HE vs U1-34H, U1-36NE and U1-34HN: which one to choose?

The real differences between the U1-36HE and the closest Long models:

| Model | Capacity | Dimensions (mm) | Weight |
|---|---|---|---|
| Long U1-36HE (this one) | 36 Ah | 197 × 131 × 180 | 11 kg |
| Long U1-34H | 34 Ah | 197 × 131 × 180 | 10.5 kg |
| Long U1-36NE | 36 Ah | 197 × 131 × 168 | 11 kg |
| Long U1-34HN | 34 Ah | 197 × 131 × 168 | 10.5 kg |
| Long U1-34HE | 34 Ah | 197 × 131 × 180 | 10.3 kg |

- Long U1-34H: 2 Ah less, the same dimensions.
- Long U1-36NE: the same capacity, a different height (168 mm instead of 180 mm). It is the option if your battery tray cannot take the 180 mm height of the U1-36HE.
- Long U1-34HN: 2 Ah less, a different height (168 mm instead of 180 mm). It is the option if your battery tray cannot take the 180 mm height of the U1-36HE.
- Long U1-34HE: 2 Ah less, the same dimensions.

## AGM technology in the U1-36HE

The U1-36HE 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.

## What to look at before buying the U1-36HE

- The U1-36HE needs 197 × 131 × 180 mm of space: measure it with the hold-down clamp in place.
- With 36 Ah, the U1-36HE replaces an original battery of that capacity or slightly less.
