I purchased this device with a new bosch agm s5A8 battery, after six months of use I once left the battery on charge for 2 months as I was leaving abroad, upon arrival I found this device inoperative and a new battery dropped to zero, and the instruction allows you to leave the charger on for a long time time to keep the battery fully charged. So I don't recommend buying this device. Fell for the price Damaged expensive battery use Winso 139700 few months |
