Direct replacement for Dell PERC controllers

This lithium battery replaces the original cache backup unit in Dell PERC H710 and H710P controllers used in PowerEdge R620 and T420 servers. It matches the factory part numbers including 07VJMH, 70K80, 070K80, 37CT1, H132V, 7VJMH and T40JJ. The pack restores write-back cache protection during unexpected power loss.

Compact lithium cell with safety certifications

The single-cell pack measures 46.12 by 36.2 by 5.14 millimetres and weighs 42.8 grams, fitting the controller's existing battery slot without modification. Built-in circuitry provides overcharge, over-discharge, over-voltage and short-circuit protection. The cell carries ISO9001, RoHS, CE, UN38.3 and MSDS certifications for safe handling and transport.

Ready-to-install backup power

Supplied as a one-pack unit, the battery requires no additional cables, brackets or configuration software. Installation consists of removing the depleted cell and inserting this replacement, after which the controller automatically recognises the restored backup capacity. Buyers needing multi-pack kits or higher-capacity alternatives will need a different product.

Questions about this item

What battery voltage and capacity does the Estry replacement supply for the PERC H710 controller?

The pack delivers 3.7 V and 850 mAh, matching the original specifications for the PERC H710 and H710P controllers.

Will the 46.12 mm by 36.2 mm by 5.14 mm battery fit inside a PowerEdge R620 or T420 chassis?

Yes, those dimensions and the 42.8 g weight are identical to the Dell 07VJMH and 70K80 modules, so it seats correctly in the RAID controller slot.

How is the battery installed and which orientation mistake should be avoided?

Power down the server, open the chassis, unplug the old module from the PERC H710 or H710P board, then press the new pack in with the connector key aligned — reversing the polarity will prevent the controller from recognising the battery.
