Does the 110Ah leisure battery require venting?
Some leisure batteries have air vent holes at each end near the top edge. These release hydrogen gas build up during recharge. The 110Ah battery does not seem to have these built in. However, the printed instruction leaflet stuck to the case describes the need to vent at least one hole and plug any others with a welch plug. This seems contradictory - is there a need to vent it for safety and if so how?
