Bought my second of these in order to euthanize the first after nearly eight years of faithful service. My load testing was starting to indicate that the previous battery was finally deteriorating. Kudos to Aircraft Spruce for their inventory management in not allowing these things to get old in their warehouse. The battery they shipped indicated that it had been manufactured just three months prior.

Battery arrived in 2 days, was well packaged. It was 6 months old so checked the voltage as per the included instructions which indicated 25.45 volts. Instructions said to charge it if below 25.5 volts so did so. Installed perfectly in C172N. Keeping a peep charger on it as per Concord recommendations. Have high expectations that it will last more than 3 years like the previous Gill.

First one lasted 8+ years so replaced with another identical model. They live on a BatteryMinder/desulfator when not in flight or on a trip. Excellent product.

The RG24-15M has a vent.

Should be an RG24-11 or RG24-11M if you require the manifold.

200 CCA.

Q: What is the difference between the RG24-15 and the RG24-16?
