About Link 1000 Settings

Battery Capacity

The default setting is for a battery with a 200Ah capacity. Change this setting if your battery has a different capacity.

You can test battery capacity by following the procedure on page 42.

The most accurate way to find the capacity is to ask for the manufacturer’s 20 hour rating.

Estimated Capacities for 12 Volt Flooded Batteries

The values listed below are estimates for 12 V flooded batteries except when noted.

Battery Size	Capacity (Ah)
U1	34–40
Group 24	80
Group 27	100
Group 30	120
Group 31	95–125
4-D	140–160
8-D	200

L-16 (6 volt)	340–415

Estimated Capacities for Gel Cell Batteries

Gel cell batteries usually hold 15% fewer Ah for a given size. For example, a Group 27 gel cell stores about 85Ah.

Estimated Capacities for Multiple Batteries

Parallel Connection If you are using a single battery bank that consists of two or more batteries connected in parallel, multiply the Ah capacity of a single battery by the number of batteries used. For example, if three 12 volt Group 27 batteries are connected in parallel, use 300 Ah (100 Ah x 3) for the battery capacity.
