Entel CLB750G Primary Lithium Battery for GMDSS Radios

The Entel CLB750G Primary Lithium Battery has a fundamentally different role from the HT644 and HT649 radio units in this family: it is a reserve power source for one-time emergency use, not a standalone communications device or a rechargeable pack for daily shifts. It uses lithium-metal primary chemistry and is rated at 9 V with a capacity of 1800 mAh. That role places it in the readiness inventory for the Entel HT649 GMDSS survival craft portable radio. For a marine operations manager, the purchasing decision is therefore about matching the pack to the correct device and emergency purpose, then managing it as a dedicated response item rather than placing it into the routine charging and rotation process used for everyday radio batteries.

How the Entel CLB750G Primary Lithium Battery Is Used

The CLB750G serves battery applications for GMDSS two-way VHF radiotelephones and EPIRB equipment. Its non-rechargeable primary design gives the deployment workflow a clear boundary: assign it to emergency duty and replace it after activation instead of returning it to a charger. This distinction matters in procurement and stores management. The pack should be treated as a readiness consumable tied to a specific emergency asset, not as a substitute for a rechargeable lithium-ion battery rotated through ordinary work shifts. Recording the CLB750G model clearly on stock records and maintenance requests also reduces the chance of mixing it with other marine communications power packs.

Where It Fits in Saudi Marine Operations

This battery type fits vessel operators, port service teams, offshore support operations, and organizations responsible for survival craft communications or emergency equipment stores. During a readiness review, a safety officer can associate each pack with its assigned device, identify it as a one-time primary battery, and keep it outside the normal charging workflow. Separating daily-use power packs from emergency-only inventory makes the issue process clearer for technicians and reduces the risk of assigning the wrong type of battery to equipment reserved for a critical event.

The 9 V rating and 1800 mAh capacity provide two direct references when checking the pack against equipment requirements. Capacity alone should not decide the match: the CLB750G model, lithium-metal primary chemistry, and one-time emergency role are all part of the identification. On a site operating several marine radio models, a purchasing team can use those characteristics together to review a replacement request before the battery is released to the vessel or maintenance team.

Position within the Entel Marine Family

The CLB750G differs from the HT644 and HT649 because it is a battery pack rather than a handheld VHF radio. Its clearest intended pairing is the Entel HT649 GMDSS survival craft portable, while the compatible-model list also covers the Entel HT544, HT642, HT644, HT649, HT782, HT783, HT844, HT883, HT944, HT983, HT844IIA, and HT885IIA. That list gives inventory managers a practical basis for supporting multiple Entel units with one identified pack, while retaining model and application checks as part of the issue procedure for each asset.

Procurement and Deployment Notes

Before ordering, match the CLB750G name to the radio model on the work order and confirm that the requested item is a non-rechargeable lithium-metal primary battery. At receipt, identifying it as a one-time emergency pack and separating it administratively from rechargeable shift batteries makes its role unambiguous to technicians. This approach helps a facility manager understand that the pack supports readiness rather than routine daily power. Where a site operates several compatible models, the store request should identify the intended radio alongside CLB750G so the maintenance and operations teams can keep allocation clear.
