frankS Posted March 31, 2020 Share Posted March 31, 2020 Hi all. I have a smallish battery charger that does the job most times for charging ordinary battery's , however to charge small battery for powering my NBN back up the charger doesn't appear to work. I have 2 of these battery's that I alternate between each other when needed and have another charger that charges them. The charger doesn't light up any of the charge modes and was wondering if anyone could explain to me why this is, and if there is something I am doing wrong ?. Sorry for the out of focus pictures .

dmck Posted March 31, 2020 Share Posted March 31, 2020 My first thought is the clips are not actually touching the battery terminal(s). There may be a plastic lip on the ends that keeps the metal of the clip away from the terminal. Are you saying you have a third charger that DOES charge the NBN battery(s) ?

kingie chaser Posted March 31, 2020 Share Posted March 31, 2020 (edited) Hi Frank, It looks a bit similar to my Ctek. You have power but have you tried to actually change the mode? I have to select the right mode to start charging, Eg press mode until it lights up 12v Hope that helps.

Smobaby Posted March 31, 2020 Share Posted March 31, 2020 If the battery is dead flat the newer charges won’t work they need a minimum charge to activate the charger. Try jumper leads to a good battery then connect the charger. 1 Link to comment Share on other sites More sharing options...
