Prices have got to a stage that one 9v NiMH rechargeable battery is within a few bucks of a 9v Lithium battery.
Is it now a case of six of one and half a dozen of the other, to support rechargeable batteries in certain situations?
I'm talking about backup batteries for the call-points I produce.
Usually, I use a NiMH 9v battery, which is trickle-charged over time to keep it ready for use.
Trickle-charging for years on end will eventually kill the battery, so should I just now be using 9v Lithium batteries do you think?
Lithium batteries can't be recharged, but they have an exceptional shelf life, so they will last for about the same time as a NiMH battery being trickle-charged for years if you see what I am getting at.
