Battery charging problem
 

As above its been on charge for 48 mins and only put 528 in ! Voltage reads 8.365 and charge rate is at 0.28 , all my other battery's have charged fine , this one doesn't want to end , is it safe to carry on charging ? Any ideas as to why its taking so long

what batterys
what type ie saddle sticks 2s 3s etc
could be one of the cells is badly out of balance.?

There 2s stick overlander sport track 5000

does your charger have facility to see what each individual cells are at?

No it doesn't , it's now been on for 80 mins put 660 in and charging at 0.26 and voltage is 8.387

sound to me like there out of balance are you balance charging them

Yes balancer on the figures seem to be going in the right direction , just so slow

It's now finished :thumbsup: s1 shows 4.200 and s2 slows 4.184 is this balanced enough ?

should be ok but would say that's why it took so long bet the were way out to start run them in your car down to 6.5 volts then try rebalance charging them
