When covert military devices are required to operate for extended periods the 160Ah version of the M1 battery (CS0033) is the ideal trade-off between energy, size and weight. Measuring 255x231x75mm and weighing <6.7Kg the CS0033 provides outstanding energy density thanks to its Lithium Thionyl Chloride cell chemistry.

The hard-cased CS0033 features an integrated 1metre long cable which is terminated in a standard Amphenol connector meaning that battery and device can be conveniently and covertly located according to operational requirements.

The CS0033 carries NSN 6135-99-617-2805 and fully complies with MOD Defence Standard 61-21 Supplement 049
