Megger 1002-552 Spare Li-ion Battery Pack, 10.8 V 5.2 Ah

Megger 1002-552 Overview

A 5 kV or 10 kV insulation tester whose battery no longer holds a charge ends up tied to a wall socket. The Megger 1002-552 is the factory spare pack that restores battery operation: a 10.8 V, 5.2 Ah, 56.16 Wh Li-ion pack that, according to the S1 /2 datasheet, meets IEC 62133-2:2017. Megger’s user guides say the pack should be replaced when it no longer holds a charge and that only Megger battery packs must be used.

Who the Megger 1002-552 is for

Owners of these Megger insulation testers, all of which list the 1002-552 as their spare Li-ion pack:

• Expert Megger S1-568/2, S1-1068/2 and S1-1568/2 (S1 /2 datasheet and user guide)
• Megger MIT515, MIT525, MIT1025 and MIT1525 (MIT515/525/1025/1525 user guide, accessories for all models)

The S1-1568/2 and MIT1525 each use two packs, and Megger’s instructions say both packs must always be replaced together.

Megger 1002-552 Key Features

What the 1002-552 brings back to your tester:

• Megger-specified pack: the user guides state that non-Megger packs may affect product safety performance
• Rated 10.8 V, 5.2 Ah, 56.16 Wh Li-ion; the S1 /2 datasheet states compliance with IEC 62133-2:2017
• Megger quotes a typical 6 h per charge for the 5 kV models (S1-568/2, MIT515, MIT525) and 4.5 h for the 10 kV models (S1-1068/2, MIT1025), both measured with continuous testing into a 100 MΩ load
• Charge time of 2.5 hours from deep discharge and 2 hours from normal discharge, charged inside the instrument from AC power
• On the S1 /2 testers, a 30-minute quick charge gives about 1 hour of operation at 5 kV into 100 MΩ

Megger 1002-552 Fitting and Battery Care

Megger’s S1 /2 and MIT user guides describe the job and the care routine:

• Switch the tester off and disconnect the AC supply, test leads and all other equipment before opening the case; never run the tester with the case open
• The pack sits under a grey moulded cover held by four screws, inside the lower case
• Charge only between 0 °C and 40 °C ambient; a full charge takes up to 2½ hours, and the S1 /2 guide advises 3 hours for the first charge
• Charge at least once a year, preferably once a quarter, and store the tester somewhere cool and dry, avoiding sub-zero storage

Megger 1002-552 FAQ

Questions owners ask before ordering the 1002-552:

• Does it fit the MIT515/2, MIT525/2 or MIT1025/2? We do not claim that. Megger’s MIT515/2, MIT525/2, MIT1015, MIT1025/2 and MIT1525/2 user guide lists a different spare battery, part number 1008-002, so the 1002-552 is not the listed part for the /2 range. Send us your tester’s model and serial number and we will confirm the right part with Megger.
• How many packs does my tester need? One for the S1-568/2, S1-1068/2, MIT515, MIT525 and MIT1025; two for the S1-1568/2 and MIT1525, replaced as a pair.
• How do I know the pack needs replacing? Megger says the Li-ion pack should be replaced when it no longer holds a charge.
• Can I charge the pack outside the tester? Megger’s documents describe charging in the instrument by connecting AC power to the IEC socket; they do not describe a separate charger.
