K2-KBT2 battery

The battery in my K2, KBT2 does not charge any more.
With 13,5 volts at J3 socket, I measure this same 13,5 v on the
terminals of the battery, but it does not charge.
The battery is 6 years old. Could it be kaput?

Re: K2-KBT2 battery

Those gel cell batteries do have a lifetime, and I would think 6 years
of life for one is good. Time for a new one.

If you got six years out of a lead acid battery, you are doing good. Batteries Plus has a replacement with slightly less capacity for just over $19. It is 2.2AH rather than 2.9AH.

To your question, yes, est kaput!

My documentation specifies the following battery:

http://www.power-sonic.com/images/powersonic/sla_batteries/ps_psg_series/12volt/PS-1229_10_Dec_15.pdf

which is according to the manufacturer is a 2.9AH SLA (sealed lead acid) battery. I know my kit was assembled in 2010. Not sure when it was purchased as I am the second owner. Maybe at some later date Elecraft has switched to a Gel Cell.

I replace my battery with an equivalent with slightly less ampere hours (2.2AH) as it was locally available (Batteries Plus) and the cost was nominal at $19.26.

Re: K2-KBT2 battery

Jim,

In the common lexicon, a gel cell is the same as an SLA battery.

My KBT2 failed as well many years ago. Rather than replace it, I bought 2 x 1.5A 11.1 V battery pack from batteryspace.com. Now they they have higher capacities. Much lighter and it seems to last forever. I charge it through a separate jack at 12.8V.

K2-KBT2 battery

In reply to this post by Jim Rogers, W4ATK

Hello Gentleman,

The battery technology for Li-Po is very mature. If you wish, please consider a
Li-Po battery pack at 3.3Ahr capacity. Light weight and more power but of
course, you have to select good quality one with protective circuit PCB.

cheers,

Johnny VR2XMC

Re: K2-KBT2 battery

Johnny, LIPOs have a tendency to burst into flame if not treated with great care. I always carried my RC lipos in a metal container after having one burst into flame. Scary!

I know some are using Lipos and they are a option, so please do not send me hate mail if you have gone that route. :-))

Yes, James. I always insist on good quality battery and use intelligent chargers.
