The battery fits in the caboose cab. When the battery runs down I remove the cab, remove the + and - wires and plug the battery into the charger. The battery used to be enough for about 1 1/2 circuit around the 600’ of main. Now it is only good for half a trip so I need a new battery.
What is a good option for this? I have looked at other tool batteries since they seem to have a longer life with some reaching 9.0 mAh. I have a basic charger for both nicd and Lipo batteries.
I’m hesitant to take one of these batteries apart like so many do, to attach power leads and a jack for recharging but I can follow a diagram if someone can steer me to one.
Of course the cost is a factor so I need to keep this under $50 if possible.
Any ideas for me?
