Well we decided on the BD Ni-Cad 18 volt. But it wasn't our first choice.
The first one we tried was the Lithium-Ion Ryobi Hybrid. It's AC-DC, didn't even dawn on me that would even have been an option. The 60 minute charge time was a big plus along with the newer battery technology.
Got it to her place and setup the charger and drug out the cord to try that portion of it while we waited on the battery. It's a single string and operated like one would expect from a battery powered unit. To me it felt slightly anemic but worked well and she liked it and that's all that matters.
Once the battery was done she gave that a run. I didn't try the battery myself but she said it was the same as being on the cord.
So we thought we had a winner. Right up till she tried to remove the battery herself. She couldn't do it. Didn't have enough strength in her hands to squeeze both tabs at the same time and pull. We both agreed this was just not going to work. To bad too, it was the only fault we could find with it. Boxed it up and back to HD.
At HD I noticed all the Ryobi's were the same as to how the battery attached so the whole brand was out of the running. That left only BD and their only model in the same weight class was the Ni-Cad 18V. Older technology and a 9hr charge time, but came with 2 battery's.
And it was cheaper, so much so I also bought their lowest priced standard corded trimmer (30 bucks) and still left with change in my pocket.
Should of seen her face when I walked in with 2 trimmers on my shoulder. And also her face when she tried and succeeded in removing the battery on her own.
Losing ones interdependency has gota suck, I know I'm not going to deal with it well when my time comes.
This all went down last weekend and I talked to her yesterday. She loves it. Says battery's last about as long as she can go anyway. Alls good, everybody happy happy happy.
Thanks guys.
