Section 15 - Care and Maintenance
15.1 Battery Care
The RD1500 uses a 9-Amp-hour, 12-Volt sealed lead acid battery. It is fused with a 10 Amp fuse to
protect it from short circuit damage.
The battery unit should run the RD1500 continuously for 6 hours before recharging is necessary. If long
days of data surveying are typical, a second battery may be useful.
The battery is strapped onto the cart base and is normally recharged without removing it from the cart.
However, the battery can be easily removed for maintenance or for recharging, if required.
If batteries are maintained in a charged condition they will give long life and reliable service. Improper use
and lack of maintenance will greatly reduce their life.
Sealed lead acid batteries should NEVER be left in a discharged condition for any period of time. Charge
the batteries as soon as possible after use.
Charge the battery at room temperature whenever possible.
The RD1500 has a voltage monitoring circuit that will turn off the unit when the input voltage drops below
10.8 volts.
If a battery has been deeply discharged or left in a discharged condition for some period of time it may not
accept charge immediately when it is connected to the charger (the fast charge light will not illuminate). If
the fast charge light does not come on within 6 hours the battery should be considered damaged and
should be discarded.
Do not assume that a battery that is still charging after 8 hours is nearing the end of its charge cycle.
Typical charging time for an empty battery is 12-14 hours from the start of fast charge.
Ensure that the batteries are fully charged before storing. If practical, store the batteries in a cool place.

electrolyte may freeze and possibly split the case.
15.2 Cable Care
1) The cable connectors as well as the connectors on the GPR Sensor and Display
Unit need to kept clean and free of dust and moisture. Use a brush or air spray to
clean dust, lint and other foreign particles from these connectors.
2) When the system is not being used, make sure the connections are protected to
prevent dust and moisture from collecting inside. If the connectors are exposed,
cover them with some sort of dust cap.
3) Cables are designed to be as tough as practical.
4) Careless and/or improper use of cables, such as making them carry loads that they
are not designed for, can cause internal damage.
