apm alternative on amd64, to check battery level

[Mayuresh <mayuresh%acm.org@localhost>]

I recently switched from 7.0 i386 to amd64.

#uname -a
NetBSD laptop 7.0 NetBSD 7.0 (MYKERNEL) #0: Wed Nov  4 20:53:55 IST 2015
root@laptop:/usr/src/sys/arch/amd64/compile/MYKERNEL amd64 x86_64 Intel
686-class NetBSD


I used to use apm command to check battery level of laptop.

Now apm says:

#apm 
apm: cannot contact APM daemon and cannot open /dev/apm: Device not
configured


Following page gives an impression that there won't be apm on amd64:

However following page doesn't describe alternatives like powerd

What command / tool can I use on amd64 to know the battery level?
