## Description

## Lemania Energy T3: compact battery tester (12V)

The Lemania Energy T3 is for anyone who wants to know quickly whether a 12V battery is healthy and whether the starting and charging system is doing its job, without fuss: it fits in your hand (80 x 80 x 22 mm) and weighs 0.2 kg.
Its only twin is the T4: same data sheet, but with a 200 cm lead instead of 100 cm. On large vehicles, or when the battery sits far away, the T4 is handier. To print the report or test 24V alternators, look at the T11.
It takes lead-acid from 100 to 2000 CCA and lithium from 20 to 1000 CCA.
