6. BATTERY CHARGING AND MAINTENANCE
BATTERY CHARGING
It is es s ent ial t hat a sui tably vent ilat ed defi ned area exis ts in each dealers hip / ret ailer for bat tery charging. Li kewis e, anarea s hould be al lot ted for s crap batt eries , and clearl y indicat ed as s uch. It is recommended t hat dealers / ret ail ers al wayshave full y charged batt eri es ready for us e. However t he bat t ery MUST BE tes ted and charged i f neces sary every mont h, andcharged aft er three months i rres pecti ve of any t es t.
• CAUTIO NS:
Bat teri es mus t be re-charged aft er a maximum of 3 mont hs st orage (s ee Storage His tory s heet i n t he New VehicleStorage Manual ).
It is very important t hat when chargi ng bat t eries us ing the t racti on charger or ot her s t and-alone chargers t hat thecharger i s s et for t he correct t ype of bat tery before chargi ng commences . If t he wrong swi tch i s s elected t he res ult woul dbe a bat tery that i s not charged full y and / or overheat ing can occur. Fol low the manufact urers operat ing ins truct ions .
Do not charge AGM bat t eries wit h vol tages over 14.8 volt s as t hi s wi ll damage the bat tery.
To bri ng a s ervi ceable but di scharged batt ery back t o a full y charged condit ion proceed as follows :
Check and i f neces s ary t op-up t he batt ery el ect rolyt e level.Charge t he batt ery us ing the Mi dtroni cs Diagnos t ic Charger (USA) or Tract ion Charger (all other market s) foll owingt he manufact urers operati ng ins t ructi ons .
• NOTE: W hen us ing the Mi dtroni cs Diagnost ic Charger, aut omati c mode mus t always be us ed. Aft er chargi ng and anal ysi s,t he charger may di s pl ay ‘Top-Off Charging’, pres s STOP t o end. Do not s top chargi ng unt il t he current falls to 5A or les s,otherwis e t he batt ery wi ll not be ful ly charged.
POST-CHARGE TEST METHODS
New Batteries, Batteries in Storage and In-Service Batteries
The purpos e of thi s tes t is to ens ure that t he chargi ng process has full y charged the bat tery.
• NOTE: IT IS RECOMMENDED THAT THIS TEST IS CO NDUCTED AT LEAST 24 HOURS AFTER THE CHARGE CY CLE ISCOMPLETED.
Page 1819 of 3229

CAUTION: DO NOT connect the tes ter t o any other circui t or chas si s point .
1. Att ach the Midtronics Test er to the bat tery.
2. Fol low the i nst ruct ions on t he tes t er t o t est the bat tery. Ens ure t he correct batt ery type and s ize i s s elect ed.
3. Perform the acti on based on the t es ter res ult s (s ee the t es ter res ult s chart i n the Vehi cl es in Servi ce s ub -s ecti on ofDetermini ng Batt ery Condit ion Secti on).
4. Ent er the readings and t es t code obtained on the In Servi ce Bat tery Report Form.

BATTERY REPLACEMENT
If it is det ermined t hat a bat tery requires repl acement, al ways refer t o t he appropri at e s ecti on of the works hop manual forins t ructi ons on removing and i nst all ing t he batt ery from t he vehi cl e.
On i n s ervice vehicles fit ted wit h a Bat tery Monit oring Sys tem (BMS), t he BMS module must be res et foll owing t heins t al lat ion of a new bat tery. The BMS module reset procedure must be performed us ing an approved diagnost ic sys tem.
CHECK/TOP-UP BATTERY ELECTROLYTE – Only Applicable to certain Flooded Typ es of Battery.
• W ARNINGS:
AGM TECHNOLOGY BATTERIES ARE FULLY SEALED FOR LIFE AND NO ATTEMPT SHOULD BE MADE TO CHECK OR TOPUP THE ELECTROLY TE LEVEL.
BEFORE CHECKING AND TOPPING-UP THE BATTERY ELECTROLY TE, REFER TO THE HEALTH AND SAFETYPRECAUTIONS SECTION.
Check t o ens ure t he batt ery is of a t ype s uit abl e for t oppi ng up. Thes e t ypes of batteri es wil l have cell pl ugs vi si ble on thet op face of the bat tery or a removable acces s panel t o all ow acces s t o t he cel ls .
On bat teries wi th a cl ear or opaque cas e and l evel marks, check the el ect rolyt e level by vis ual i nspecti on of the maxi mumlevel indicator mark on t he batt ery cas ing i ndi cat ing adequat e l evel above the bat tery separat ors .
On bat teries wi th bl ack cas es, remove the cell pl ugs or acces s panel and ens ure the el ect rol yt e l evel is level wi th theindicat or i n t he cel l hol e. A flas hl ight may be requi red to s ee t he electrolyt e level on thi s type of batt ery.
CAUTION: DO NOT overfil l.

EQUIPMENT
Approved diagnos t ic s ys tem wit h current probe or Digit al Mul ti -Met er (DVOM) wit h current probe.
METHOD OF MEASUREMENT
Using an Approved Diagnostic System
1. Swit ch off all elect rical loads and ensure t hat t he i gni ti on is off.
2. Connect the current probe t o t he approved di agnos ti c s yst em.
3. Calibrate t he probe.
4. Ins t al l a clamp around the bat tery lead/junct ion box l ead.

• NOTE: The batt ery may be t es t ed eit her on a bench or on t he vehicle.
In the cas e of on-vehicle tes ti ng, t he batt ery must be is olated from t he vehi cl e by removal of t he bat t ery negati ve(-) cable from the bat tery t ermi nal before t he measurement is t aken unl ess the vehicle has a transi t rel ay fi tt ed oris in t rans it mode.
A vehicle which has had it s batt ery charged or been dri ven in a 24 hour period before t he tes t , must have i ts s urfacecharge removed us ing one of t he fol lowi ng methods :
1. If 24 hours have pas s ed s ince the las t ti me t he engine was run or the bat tery charged, proceed t o `Part 2 - Bat teryTest '.
2. Turn on t he i gni ti on. Swi tch on t he headlamps on hi gh beam for a mini mum 3 minut es .
3. Swit ch off t he headl amps . For vehi cl es tes t ed aft er t he t rans it relay has been removed, di s connect t he batt ery byremoval of the negati ve (-) cabl e. Vehi cl es wit h a trans i t relay fit t ed or wit h a l ow current t rans port mode enabled do notneed to have t he batt ery di s connect ed.
4. W ait a maximum of 5 mi nut es before recordi ng tes t res ult s for any bat tery measurements .
Part 2 - Battery Test
• NOTE: The batt ery s urface charge mus t be removed before t his t est i n accordance with the procedure in Part 1 above.Ensure t hat t he batt ery terminal connect ors are clean. W hen connecti ng t he Midt ronics t est ing equipment , connect the REDclip to the pos it ive (+) batt ery terminal fi rs t, and t hen connect the BLACK cl ip t o t he negat ive (-) bat tery t ermi nal .
