Even with proper storage and regular charging, rechargeable batteries eventually need to be replaced. This factory-approved 6V 5 Ah sealed lead acid battery fits in all TimeMark Gamma, Gamma NT and Beta traffic counters.
Instructions for changing the battery can be found in your counter's user manual. Manuals for all TimeMark counters can be found in our online Library (sign in required).
All batteries slowly lose their charge. To prolong the life of your battery, recharge it regularly, even when it's not being used. If the voltage drops too low for too long, it may not be possible to recharge it.
We recommend recharging counter batteries at least every 2 - 3 months or before they drop below 6.0 volts, whichever comes first. It doesn't hurt to recharge them more often, though. All of our chargers are designed to stop and hold once the battery is fully charged.
