![]() The solar light batteries in my garden are dead. Upon replacing them, I realized they were the old Ni-Cd rechargeable batteries.
I have heard that these batteries are not so good for the environment because they contain toxic chemicals (see Wikipedia). I would like to use Ni-MH batteries instead. Would this be recommended or will slowly charging these batteries using solar panels shorten its life span? |

![]() They will work great. Nimh batteries typically have 50 per cent more capacity vs nicd in the same size and do not build up memory as bad as nicd batteries.

![]() They both accept the overcharging abuse of long sunny days with no charge control equally well. If you were charging them at a high rate with a NiCd charger, they have the potential to overcharge at a high rate, generate a bunch of heat and usually fail quickly. With a slow charge from a solar panel, it's a non-issue.
