- Very long runtime on high-draw tools
Questions and answers
- Which lasts longer on a circular saw?
- The 12 Ah. At the same draw it holds roughly 2.4 times the charge of the 5.0 Ah, so expect about 2.4 times the cuts per charge.
- Is the 12 Ah too heavy for a drill?
- It is 3.36 lb versus 1.5 lb, so it makes a compact drill nose-heavy. For overhead or one-handed work the 5.0 Ah is the better pick.
- Is the 5.0 Ah worth it at $74.99?
- That is the eBay listing price as of October 31, 2026. It is a fair price for a 5.0 Ah pack with a fuel gauge, but compare it against the 12 Ah's price per amp-hour before buying.
- Do both fit the same tools?
- Yes. Both are Hercules 20V lithium-ion packs and work with all Hercules 20V cordless tools.
- Which should I buy first?
- Start with the 12 Ah if your main tools are saws or grinders. Start with the 5.0 Ah if you mostly use drills and drivers.
