GBZ
It depends on application, I would IMO suggest that is designed for same duty & of similar capacities no problem.
As I have a lot of additional lighting on my vehicle (floodlighting, beacons etc) I have used a split charge system for years. In the early days, cos of space constraints I used a gel as the "lighting" battery, though not designed for the job it lasted about 6 years.
I now use a leisure battery (nearly 9 yrs old) for same job. Loads on it can reach 15 - 20A.
