Purchased a BPS Xps 4/4 8amp charger yesterday along with two stowaway 27- 105amp hour 182reserve capacity .. plug both batteries up last at around 6pm. Woke up at 430 to go fish and the charger was still going .. I got close to the batts and could hear bubbling .. took em off charger and went fishing... I used one battery and it lasted me from 630-noon trolling the whole time .. when I got back to the ramp it still has 1/3 charge.. I checked before I trolled across the lake (177acres) and it had 2/3 charge so I'm assuming it was a high 1/3 left. After all that my question is.. is that a normal charge time for a first charge or do I need to return the charger or batteries??? The batteries were cool to touch as well.thanks guys
