Pretty simple test needs a kill a watt meter and a scale and a battery chainsaw and a gasoline one. Fill the gasoline one up with bar oil and mix. Go cutting and approximate the use on the battery one with the gasoline/mix one. Refill the bar oil on the gasoline one and record the weight of mix used. Reset the kill a watt meter and record the electricity used to recharge the battery or batteries used.
It was kind of imprecise,
but I doubt I can be off by more than twice or half.
BLI300+Bli200x take 0.54 kwh or 540 watt hours input to the charger.
Two cycle chainsaw Makita 3601 used 6.5 ounces of mix in try 1 at this. Call it a cup or 1/16 of a gallon.
The two batteries weigh 7 pounds 5 ounces.
As to the cost, I studied my electric bill here in CT it seems to cost $9.62 to be hooked up or have the meter read monthly and 29.3 cents a kwh after that. Supply is only 9 cents but we have high grade new robust poles and lots of work for tree trimming contractors.
A cup of mix I put at 47 cents, $6 a gallon for REC 89 or 90 and $1.50 for the oil, $7.50 total
16 cents to recharge both batteries.
Invest $500 in Husqvarna batteries (assuming no promotion) and cut your fuel cost by about 2/3.
Maybe someone else would like to try the same basic thing. I think collecting the sawdust and weighing it would be a less error method.
117 pounds of Husqvarna batteries to do the work of a gallon of mix?
