/ Battery powered chainsaw #511
Lithium ion batteries should be good for at least 1000 charge cycles. If you have a business and charge the battery daily, you should be good for at least 4 years. If you are a homeowner and charge less frequently, they may be time limited but should be good for at least 10 years.
I'd be really surprised if Harbor Freight has any standardization on whose cells they're using, in building their battery packs. The ones you opened happened to be Toshiba, likely because Toshiba was the company with an overrun that month. I'd expect it's probably a different manufacturer with each purchasing cycle, driven by pricing, when it comes to any bargain-basement supplier like Harbor Freight.I will say that Harbor Freight sells only rechargeable battery packs that are produced with quality cells and I know because I look. They use Toshiba cells...
Remember, that is his PERSONAL experience and may not reflect the actual end use longevity which is entirely dependent on how you use them and what they are used in.I might get some LabTEC Lithium Batteies who Farm Project guy tested and found to the best of aftermarket batteries..
