You need a 12v battery in the system to even out the voltage fluctuations. The charger wont work without this. A 60W solar pannel is a lot to charge a small batteries. 5 to 10W would be enough.
With 60W and a 12v gel cell battery you have plenty of energy to run lights radio instruments etc if you want.
What are the best type of rechargeable batteries to use on board in the tropics?

Thank you.
Sanyo Eneloop are the best rechargeable batteries. They have a low self discharge rate and long life. There are many very poor quality rechargeable batteries that give many people the impression that they are not worthwhile. The quality products are vastly superior and only slightly more expensive.

Lotech, I'd vote for just buying a small solar battery charger for them.
Most of the solar battery chargers are poor with little regulation and very slow charging times. Useful if you are in the middle of nowhere and want to top up your camera batteries and a compact low weight charger is important, but not a good option for rechargeable on a regular basis.
A solar panel 12v battery and regulator is a much better, but bulkier and more expensive option.

The manufacturers only offer discharge rate info for the ideal temperature of 60 degree F.
The good quality LSD rechargeable batteries, such as Enoloop are still OK after 6-9 months at real world temperatures. Rechargeable batteries benefit from some use and if the batteries in a particular device, do to need to be replaced more often than every 6months or so you are probably better using non rechargeable alkaline or lithium batteries.
