Which is better for a circular saw?

The 5.0Ah pack. A 1.5Ah pack will cut out quickly under high draw, while the 5.0Ah pack gives roughly three times the runtime per charge.

Which lasts longer over the years?

Both use DeWalt lithium-ion cells rated for about 1,000 recharges. The 5.0Ah pack does more work per cycle, so it sees fewer charge cycles for the same jobs.

Is the 5.0Ah pack worth the extra $37?

Yes for most shoppers. At $110.14 you get 10Ah total versus 3Ah for $72.99, so the 5.0Ah pack costs about $11 per amp-hour against about $24.

Will both fit my existing DeWalt 20V MAX tools and charger?

Yes. Both are 20V MAX lithium-ion packs and fit all DeWalt 20V MAX tools and chargers.

Which is better for overhead work?

The 1.5Ah pack. At roughly half the weight per battery, it causes less fatigue when you work above your head.

Do either come with a charger?

No. The 5.0Ah two-pack lists the charger as not included, and the 1.5Ah pack is batteries only.
