I purchased this extra longer life battery to have as a backup to the battery that came with my cordless pole chain saw. I used it for a couple hours trimming up some Juniper trees. If you know anything about Juniper, they are a very hard wood. The saw and battery worked out great. I'll use this battery pack as my primary and the smaller one as the backup in case I run out of juice.
Works very well with the 11-inch electric shovel! However, I need to find a proper charger, because the little one included with the 2Ah battery set needs 10 hours to charge this one from empty.
I purchased this battery as a backup for my Sun Jo Mower. This way, when one is in use, the other is on the charger to be ready. I am very pleased that this second battery lasts longer than the one that came with the mower, and charges quickly.
