Which of your 40V Kobalt lithium ion batteries is the strongest/lasts longer? It is hard to compare the 3 on your website as the "details" in the descriptions is different.

Asked by: Hugger1
 I purchased the 40V 4 am. In May/24. This lasts longer and much charges faster than the 2 amp. Perhaps the 2 amp can be used as a cheaper backup. I don’t know about the 6 amp. but suspect that it may last longer given the increased strength. The same charger can be used for all three.

I have an older Kobalt lawnmower Model KM-1640 with original battery Model KB 440-06 and charger Model KRC 60-06, could this new battery Model KB 440-03 be safely used in both, the old lawnmower and the old charger?
