They are trojan 100 ah 12v batteries, they are stored in a room at 80 degree average temperature. For what I understand , the 10 watts solar panel and 4.5 A charge controller will not properly do the trickle charge process to keep these batteries in constant 100% charge. Would  a bigger panel and Charge controller devices do the trick?  The batteries will be unattended for 6 to 8 months at a time, and in use for 2 to 3 weeks when attended. please advise.
