Got a solar powered garden light with white Led lights with single AA rechargeable 800mAh,1.2v battery. Will be using indoors where there is not enough light to recharge battery so I want to add an external power supply. I want to use a switched battery holder containing 2 AA 1.5 batteries. I will disable the solar charging circuit so it does not try to charge batteries when I have the lights turned on during daytime. Then I will wire the external battery supply in parallel with the original single battery holder so the power will be supplied to the LED lights through the circuit board. My concern is increasing the supply voltage from 1.2 to 3v. I do not have the technical specs for the lights but have read that white LED's typically take 3+ forward volts. My lights have four wires going to each one so I assume they are wired in parallel. do I have enough information to be confident the higher supply voltage will not damage the lights? Thanks.
