gravity. Use a rag dipped in ammonia, or baking soda
solution.

High Rate Discharge

Whenever you have time to do so, make a 20-minute high rate discharge
test on the rebuilt battery, as described on page 266. This test will
show up any defect in the battery, such as a poorly burned joint, or a
missing separator, and will show if battery is low in capacity. If the
test gives satisfactory results, the battery is in good condition, and
ready to be put into service, after being charged again to replace the
energy used by the test.

EXIDE BATTERIES

Exide batteries may be classified according to their cover
constructions as follows:

1. Batteries with single flange covers, as shown in Figs. 15 and 238.
This class includes types DX, LX, LXR, LXRV, PHC, XC, XX, and XXV.

[Fig. 238 Exide Battery, partly disassembled]

2. Batteries with double flange covers, as shown in Fig. 242. This
class includes types MHA, KZ, KXD, LXRE, and XE. The cover
constructions are-described in Chapter 3.

All Exide batteries, except types KXD, LXRE, and XE, have burned-in
lead top connectors. All types have a removable sealing nut around
each post to make a tight joint between the post and cell cover, as
described on page 19. Formerly some Exide batteries had cell
connectors which were bolted to the cell posts, but this construction
is now obsolete. Types KXD, LXRE, and XE have cell connectors made of
flexible, lead coated copper strips.

Types DX, LX, LXR, LXRV, MHA, PHC, XC, XX, and XXV have been designed
and built to meet the requirements of starting, lighting and ignition
service for passenger automobiles and power boats.

Types KXD, LXRE, and XE have been especially developed to meet the
requirements of the starting, lighting and ignition service on motor
trucks and tractors.

Type KZ has been produced particularly for motorcycle lighting and
ignition service.

Type Numbers

The type of an Exide battery is stamped on the battery name plate.
Thus, on one of the most popular Exide batteries is marked Type
3-XC-13-1. Other Exide batteries have different numerals and letters
in their type numbers, but the numerals., and letters are always
arranged in the same order as given above. The first numeral gives the
number of cells. The letters gi
