Bauer 20V 5.0Ah Replacement Battery vs Bauer 20V 6.0Ah Li-Ion Battery

Buy the 6.0Ah Bauer pack if you want the simplest, most predictable fit and runtime on Bauer 20V tools. The 5000mAh 1701C-B is a third-party replacement that cross-references several OEM part numbers and claims 100Wh, but its own listing shows a 1.5Ah spec line and a buyer report of a terminal that did not match stock. Prices were not provided for either pack, so compare them on Dela.ai before deciding.

What reviewers say

Bauer 20V 5.0Ah Replacement Battery

Buyers mostly report the pack works as advertised, with extra battery life and steady performance after charging. The main fit complaint is a terminal that differed from the stock battery on one application.

What people mention

FitMixedMost say it slides in and locks with a firm click, but one buyer had to bend a lead because the positive terminal differed from stock.
RuntimePraisedBuyers report extra battery life and steady voltage under drilling and cutting loads.
BuildPraisedThe BMS held its overcurrent threshold through repeated motor-start inrush in bench testing.
CompatibilityPraised

Questions and answers

Which pack runs longer, the 5000mAh or the 6.0Ah?: On paper the Bauer 6.0Ah pack holds more charge than the 5000mAh pack. The 1701C-B listing also shows a 1.5Ah line, so its real capacity is uncertain until you check the label.
Will the 1701C-B fit my Bauer drill?: It is cross-referenced to Bauer 20V part numbers 1701C-B, 1702C-B, 1907C-B and 1908C-B and is sold for the drill/driver and sander. One buyer reported the positive terminal differed from stock and the lead had to be bent, so check fit before relying on it.
Is the genuine Bauer pack worth the extra?: If the 6.0Ah pack costs more, you get a stock connector and a single clear 6Ah rating. The 1701C-B only makes sense if it is clearly cheaper and you accept the fit risk.
Which is better for a chainsaw or blower?: Both are sold for Bauer 20V tools including saws and blowers. The 6.0Ah pack has the higher stated capacity, which matters most on high-draw tools like a chainsaw.
Does the 1701C-B need a break-in procedure?: The seller recommends running the tool at half load for two cycles before full torque so the BMS sets its overcurrent thresholds. That advice is specific to this replacement pack, not the Bauer 6.0Ah.
