What this battery replaces

The Batianda pp29L is a 58 Wh, six-cell lithium-ion pack built to replace Dell part numbers 312-0625, 312-0827, 312-0844, 451-10533, 0WK371, RN873, GW240, GW252, GP252, RU586, K450N and X284G. It fits Inspiron 1525, 1545 and 1440 models as well as the 526 chassis. Buyers with other Dell laptops or non-Dell systems cannot use this pack.

Thermals and power behaviour

The cell chemistry delivers 11.1 V at 5200 mAh and is rated for more than 500 recharge cycles. UL testing confirms the pack meets recognised safety standards for temperature rise and short-circuit protection during normal charge and discharge. No active cooling is required; the battery relies on the laptop’s internal airflow.

Runtime per charge

In typical use the battery powers a compatible laptop for more than three hours on a full charge. Actual duration varies with screen brightness, workload and system power settings. Users needing all-day operation away from mains power should plan for a second pack or a charger.

Questions about this item

How do I install the 6-cell 58Wh battery in my Inspiron 1545 and what step is often missed?

Power off the laptop, unplug the charger, slide the old pack out, insert the new pp29L unit until the latch clicks, then charge it fully before first use.

What maintenance will this 11.1V 5200mAh replacement need over its life?

No routine upkeep is required; after more than 500 recharge cycles the runtime will drop noticeably and the pack should be replaced.

What limit appears first during sustained heavy use of this RN873 compatible battery?

The pack delivers over three hours on a typical load; continuous high drain will hit the 58Wh capacity ceiling sooner and trigger automatic shutdown.
