How long does a Black and Decker weed eater battery last?
5 – 8 hours. I was not aware of the “fast charger” – I might look into buying one. I did purchase an additional battery for backup because battery only lasts 15 – 20 minutes in my weed trimmer. 3 of 3 found this helpful.
Are Black and Decker 36V and 40V batteries interchangeable?
Yes. The Black & Decker website clearly states that all their 40V MAX products are fully compatible with the 36V lithium ion system. Additionally, all the product numbers end in 36, even for the battery and charger. That indicates that even the chargers are interchangeable.

Can I use a Black and Decker 40V battery in a 20V tool?
No, not without intervening circuitry to step down the voltage to 20 volts. You can generally use a higher capacity battery (that is one with more amp hours and thus run time) but the battery itself has to be 20 volts. Higher voltages will destroy the tool.

How long will a 20V Weed Eater last?
Seems to last on average about an hour on low. Operation on the high setting is limited to about 30-40 mins depending on use. My recommendation is if you can’t complete your trimming job with a single fully charged 5.0 Ah, then a gas trimmer should be considered instead.
