Questions about this item

Does the Estry BA-400 package include any cables or tools, or is it just the battery?

The listing describes the BA-400 as a standalone replacement battery; no cables, tools or adapters are mentioned, so plan to reuse the original connector and mounting hardware from the Brother SuperPower Note.

I see several SuperPower Note models listed — PN8510MDS, PN9000GR, PN8500MDSE and others — how do I pick the right one?

Match the part number printed on your original battery to BA-400; the compatible models include PN8510MDS, PN4400, PN9000GR, PN5700DS, PN8500MDSE and PN8700MDS, so any of those will accept this pack.

What does the 1500mAh 6.0V rating actually deliver in a Brother SuperPower Note?

At 6.0 volts and 1500 milliampere-hours the pack stores roughly 9 watt-hours, giving a typical SuperPower Note several hours of run time depending on screen brightness and workload.
