Chargers as much less efficient on modified waves than sine wave.

 

More heat produced per watt consumed so less in to the battery.

 

The AL500 is also not just a dumb charger like for your car bat.

 

I agree a small genny seems the best way. Also good for the kettle

 

My earlier calcs were based on the 300s battery.

 

Yea it would be more efficient on a pure sine wave but ~£200 more efficient? Unlikely... I would say that compared to some of the skyrc and turnigy chargers used in the model world where you can set ramp rates, cycles and a whole manner of things the stihl charger, whilst containing a microchip which can sense voltage/temp and charge rates it's still a relatively dumb charger and is on the same level as the Makita chargers which can take a fair amount of abuse and won't be effected by a slightly distorted wave. That being said, you will get more efficiency out of a pure sine but it's debatable if it's worth the cost. The battery won't see any difference on its end anyway

Quite possible true. But the 500 is not cheap, is it worth the risk? The makita type were made as building site chargers so designed for iffy supply.

I have to charge my batteries indoors during the colder months. I get the red light if I try and charge them before they have warmed up a bit.
