I think your on a roll! An alternative to Lithium that the weights are so close is Odyssey Extremes. I bought all mine from BatteryMart. Each time I compare size / service ratings the Extremes are so close it has not been worth the change. Odyssey batteries have been installed in my shop to my customers who would buy them for over 10 years without a single return.
Here is the link to the PC925 specs. I fish all day in tide current with 2 of these and the charger cuts off in 4 hours of recharging.
