​Performance & Features

​The OPJT11048 is engineered for longevity and ease of use, featuring:

• ​Quick Recharge: Recharges up to 15% faster than standard jumbo batteries thanks to a special paste formulation.

• ​Ultra-Low Maintenance: Uses a low antimony alloy which minimizes water loss; you typically only need to top up water 1–2 times a year.

• ​Spill-Proof Design: Features an innovative 6x1 layout where all inlets are on one side, combined with ceramic water level indicators for easy, mess-free maintenance.

​Recommendation

​This battery is an excellent choice if you need a reliable backup for essential appliances (like a few fans and lights) in a space where a full-sized 150Ah battery might be too bulky or unnecessary. Its fast-charging capability makes it particularly useful in areas with frequent, short power cuts.
