Questions & Answers

It says it takes 180 minutes to charge. Is that true?

It says it takes 180 minutes to charge. Is that true?
Asked by: Carl
I just wanted to make one little correction here. Amps are current flow i.e. one coulomb of charge per second. Volts is a measure of electrical pressure i.e. how much force is moving an electron from one place to another. An amp hour is how many amps a battery can deliver for one hour with no loss of amperage or voltage. So in theory these could deliver Nine amps of current at 18 volts for one hour before the voltage (electrical pressure) or Amperage (Rate of electron flow) dropped. It's pretty much the most accurate way to gauge a battery for overall capacity but actual capacity varies based on how its used try to draw more than 9 amps and you'll get far less than an hour. Use less than 9 amps and you'll probably actually get much more than 9 amps out of the battery.

What is the difference between the 6.0AH and the 4.0AH??? Thank you.

Asked by: RR
I’m a 60+ female, not at all knowledgeable about lawn tools and such but I can tell you this. The 6Ah battery has more power and lasts so much longer than the 4Ah battery. I can easily handle it even though it is slightly heavier than the 4Ah plus the 2 pack batteries cost only $20 more than a single battery. It’s an unbelievable deal.

I have a charger, does the 9 ah require an upgraded charging unit?

Asked by: M1
Im charging 2, 4 & 9 Ah batts in several chargers - the p117 and a couple of the small chargers tgat usually come with the tools. They all work just fine - if the charger is designed for the 18v ONE+ system it should be fine.

do these require an upgrade to the green charger.

I have the green charger for the small lithium batteries. Do these larger batteries need a specific charger?
Asked by: stl2fun
The lithium batteries DO require the correct type of charger made for lithium batteries. All of my chargers that are of different designs and sizes, but are made for lithium batteries, will charge any of my batteries. This includes 1.5 ah all the way to 6 ah.....but it does take longer to fully charge the larger ah batteries.
