Best Power-to-Weight Ratios (Batteries) for Various Tools

Good morning everyone. It's time for me to get serious about what to put on my Christmas list this year, and it is to replace all of my corded and gas outdoor tools with battery powered. I originally was looking at Ryobi but then saw the Ego line and although the price point is higher, the reviews appear to put the Ego line at a level where I'd be comfortable buying their tools to last me many years to come, whereas the Ryobi is cheaper because they're made cheaper.

Anywho, I am looking at the below list of tools. I'm all about big batteries. Yea they're more expensive but each one should be able to last me through an entire job for one specific tool and then some. The problem I foresee is the weight of the bigger batteries upsetting the factory BALANCE of the tool. It's one thing on the snow blower and lawn mower but on string trimmers and hedge trimmers, I don't want a big counterweight behind my hands and constantly needing to strain my wrist to tilt the tool down. I'd like to know in your experience what the best battery size per tool is so that I can properly choose whether to purchase the bare tool or the full kit with battery. Thanks!

You'll be better off $ wise buying the tools bundled with the batteries. They are also balanced weight wise with the one they come with. If you get the three tools you'll have three interchangeable battery's, they charge fast and I don't think you'll ever run out of power with three 2.5 ah batteries and chargers if it just one person using the tools at a time.

On the other hand from my comment to Adrian, I could leave a 2.5 battery in each of my three tools and probably get more than one session out of each. Plus I think the mower comes with the big battery so if I ever got rid of my gas mower and picked up the Ego version, that'd be my cheaper way of obtaining the big battery.

Like HA, I buy the "full kit" for my 15" trimmer and back pack blower (a better deal).  For my trimmer, I have a 2.0 Ah battery and that works perfectly for my yard - never need to swap out the battery for another, as one full charge does the job.  As for my back pack blower, the 7.5 Ah kit was not available at the time, so I have the 5.0 Ah battery.  For this kit, I would prefer the 7.5 Ah battery instead - for longer run time of course.

I only use a 7.5 Ahr battery in my string trimmer, mower and blower. I haven't noticed a weight imbalance in the trimmer or blower, but I also haven't compared them side by side with my 2.5 or 2.0 Ahr batteries.

I use a single 7.5 Ahr battery to mow, then trim then blow my front and back yards and I usually get 2 to three uses out of a single charge. So I mow every week, but only charge every 2 weeks. I have a typical 1/4 acre lot, so not real big, but pretty typical size I think.

Adrian, would you mind swapping to the 2.5 and even just holding the trimmer and swinging it around how you normally would? I prefer your method of using a single 7.5 to handle every task without needing a charge. I've got a gas mower for now, so would only be hedging, trimming, and finally blowing to finish the day and a single 7.5 battery would prob do the job. But again I was concerned with the weight of such a battery on something like the trimmer and hedge trimmer. Overall I'd save $170 by purchasing the bare tools vs tools with the 2.5 batteries and chargers, and could then buy a single rapid charger and put the other $70 toward a 5 or 7.5 battery.

The rapid charger is nice but not a necessity.

I have the 530cfm blower and have used it with both the 2.5Ahr battery as well as the 5.0 and 7.5Ahr.  Yes it is slightly heavier but not to a point of being unmanageable.  You don't notice any difference when you hit the turbo button on the top.

As for the trimmer. if you are in the USA, they did have an offer to get a free strap with your purchase, and the shoulder strap would offset any weight balance difference.

If I were you, I would buy the kit for at least one if not two of your tools.  Look at the price break between the tool only and the kit.  Here in Canada the cost of the 15" trimmer kit was $30 more than the trimmer alone.  For that price you might as well get the battery.   I do like the 5.0 and 7.5 batteries for the length of charge, but for myself, with the blower, I don't run it at full power all the time.  mostly it's at 50-75% and I can do both my front and back yard cleanup and still have power left over even on the 2.5Ahr battery.

Took me a while, but I got it done. The string trimmer and blower both feel quite a bit lighter with the lighter 2.5 Ahr battery. I didn't really notice the weight balance as much as the heavier assemblies just made me feel more tired. They feel closer to the weight of gas equivalents, although I no longer own any gas lawn tools to compare them with side-by-side. And I did have a heavier 4-stroke trimmer for the ease of gas filling and starting.

I'll probably still use the 7.5 Ahr battery in both of them because I prefer the convenience of only charging 1 battery (even though I have 5 battery chargers, 2 of them fast chargers).

I have a small yard (for now) and have only ever really used the smaller batteries on the small handheld tools. So far so good, and I would always argue that the smaller tools will always feel lighter and easier to handle with the smaller lighter battery packs.

Putting a heavier battery pack on the handheld tools will always be a matter of personal preference. It will also depend on the length of the job and the user's physical strength.

There's always something to be said for redundancy as well. While we never plan on having something go wrong with our tools, should a battery or charger ever fail it it's nice to have a backup.

As others have mentioned, the kits with battery and charger are often a pretty good deal compared to the bare tool price and batteries purchased separately. With that in mind as well as the redundancy issue I mentioned above, it would be nice to have at least one spare battery and one spare charger.

And even though the 7.5Ah battery is the most awesome thing ever to hit power tools, ever, like ever, in the rare case you do run out of power a few minutes before you're done the job a small battery could stand in and get the job done. :-)

1) the high current draw tools like the chains saw and blower will benefit from the 5.0 AH over the 2.X AH.

2) the 15" trimmer with the 5.0 AH battery does not balance well (at least for me)

3) you can usually get the full kit for less than $100 more over the bare tool; I would always recommend that route.

4) if you ever want to sell a tool, buying the complete set will be much easier to sell (or give away) over a bare tool.

A guy on craigslist here recently sold a 2.0 AH and charger for $90.

I've got spreadsheets for dayssssss. Nothing really knowledgeable about this one, other than comparing bare tool and kit costs. The hedge trimmer has an $81.70 difference, the 15" string trimmer only a $29.96 difference, and the leaf blower a $58.74 difference. Obviously then it's a no brainer to buy the string trimmer kit since a 2.5AH battery and charger are $219.98 by themselves. The leaf blower kit makes sense too but as the point was made that it'd be good to have at minimum (2) batteries hanging around, those will be the two kits I buy. Save $80 on the hedge trimmer and put that toward the $219.99 5.0AH battery, making it more like $138. BOOM!

Your point on high current draw tools work better with larger batteries is good but then the kit that comes with them give a larger battery anyway.  I guess you can point to the 14" chainsaw kit but why someone would want that i don't know considering that the price spread is not much more than the 16" unit.  And what I find a kicker is that they sell the 14" chain and bar for far more than the 16" so it's as if they are trying to convince everyone to go towards 16" anyways.

Sorry, I'm not good with words, can I see this in spreadsheet form?
