- Long WP7-12(28W)T: 2 Ah less, the same dimensions.
- Long WP12B-4: 0.5 Ah more, a different height (130 mm instead of 106 mm). It only fits if there is room for 130 mm of height.
- Long WP7B-4: 2.5 Ah less, a different height (93 mm instead of 106 mm). It is the option if your battery tray cannot take the 106 mm height of the WP1236WT.
- Long WP1234W: 0.5 Ah less, a different case (151 × 65 × 102 mm).

## AGM technology in the WP1236WT

Inside, the WP1236WT has glass fibre separators (AGM) that hold the electrolyte. The WP1236WT needs a charger with an AGM mode that does not exceed 14.7 V.

## Before ordering the WP1236WT, check this

- The WP1236WT needs 151 × 65 × 106 mm of space: measure it with the hold-down clamp in place.
- With 9 Ah, the WP1236WT replaces an original battery of that capacity or slightly less.
