The weed eater itself, 1 battery, charger and 1 spool. don’t let the battery fully discharge – for example not using or recharging it for several months.perform “full recharge cycles” – use the battery until it runs out of power and then fully recharge it (yes, the problem is you shouldn’t recharge it, if there’s still some juice left).To prevent the memory effect of NiCd batteries (you can also learn more here): How should I treat the battery to ensure maximum lifetime?Īlways store the batteries inside your house in reasonable temperatures – never leave them on direct sun or outdoors during winter! On the other hand, they are also a lot cheaper than the 36 or 40V – plus you get the possibility to use other Earthwise 18V tools (blower, pole saw, chain saw or hedge trimmer) with the same batteries. The running time is slightly lower ( 20-30 minutes per battery) and it recharges overnight – so you may need a spare battery even if your is not extra large. The CST00012 uses 18V NiCd battery system which presents several disadvantages if you compare it to the newer 36 or 40V lithium-ions. The trimmer uses autofeed to advance the line, so no bumping is required – and users report it works fine, just needs a little help from time to time. It doesn’t have enough power to cut through thick grass or tough weeds. It’s perfect for smaller or medium yards when you just need to clear areas not accessible by a mower – around trees, fences or walls. It is designed for light trimming and cleanup jobs – so don’t expect the power of modern cordless trimmers (which cost two or three times more) or even gas machines. It is very quiet, light and the balance is also nice. And also no vibrations or noise typical for gas trimmers. The CST00012 shares all the advantages of cordless weed whackers – complete freedom of movement, no worries about dragging the cord (and winding it up after trimming) or mixing fuel.
