cant remember who asked about battery chargers but the one I have tells me what percent is left in the battery.
The make is RING and its an RSC 2 - 16 Amp SMART Charger16
You can select a 2, 4, 8, or 16Amp charge level and it also has a "Battery Recondition" facility which you can choose or if it needs it , it will do it automatically.
I put it on at 4 - 8 amps and if you're not sure before you switch the charger on there's a button to press that tells you what percent the battery has left in it - BRILLIANT !!
I bought it from a Sureparts depot and cost only £63.00 last year
