Replacement solar panel for outdoor light question

I have a shed light that takes 3 x 1.5v (4.5v total) rechargeable batteries which are recharged by a small solar panel
The solar panel has gone faulty
I have a spare working solar panel that used to be used to recharge a 6v solar powered light (product used a 6v lead acid battery)
Would this 6v solar panel damage the 4.5v shed light if I connected it up ?
IIRC I know that usually supplying excess voltage is a bad idea but as its only recharging the batteries I was wondering if theres a chance it would be OK
Also could I add a resistor into the circuit to reduce the voltage ? ( my knowledge of electronics is quite limited )

I doubt it would make any difference, just checked my laptop battery is 10.something volt and the charger output is 19v. They are usually something like that.Mr Generous - Landlord for more than 10 years. Generous? - Possibly but sarcastic more likely.0

Rechargeable batts are 1.2v not 1.5v which is why you shouldn't use them for things like wireless room statsI'm only here while I wait for Corrie to start.
You get no BS from me & if I think you are wrong I WILL tell you.0
